@Britec09
Convert GPT to MBR without losing data reverse process pls........
@@sreeshtn5545 it can't be done. It actually warns you that the process is not reversible

@@GRsBlueBiHan thank you bro for information.
@@sreeshtn5545 I don't think there's a tool for that. You need to always back up your data
I have been struggling to find out what was stopping me changing to windows 11 and this was it. Brilliantly explained. Thank you
Would like to mention that your video reminds me of a young Michael Caine.. (also incredibly well done, maybe the best I ever watched.) Now speaking as a PC tech of 30 years, I was doubtful this technique would work on my target machine. In my situation, it failed before the horse even left the starting gate. The target system is a 9th gen i3 with a Samsung 970 Pro 512g NVMe drive, no DVD, and just the simple MBR partitions, for which I added an extra D drive partition (long ago) so I could back up C to D with Macrium and have all the docs/downloads/videos/etc folders isolated safely on D. This technique is a life saver. Regardless, when I ran MBR2GPT to verify...the system insisted there was no drive 0. To make sure I was not losing my mind, I ran DISK PART and LIST to confirm that the 512 GB drive was indeed drive 0. My thoughts are that your methods may not work on an NVMe drive, due to the unique way the drive is primed for booting. Your thoughts on this would be appreciated, but it looks like all the machines I have built for the bond trading group whose machines I service, will need a total wipe out to get GPT and Win 11.
Flipping amazing. I went through all kinds of hell contacting Asus (mobo), Samsung (SSD) and MS (OS) and no-one would give me a straight answer. This was the solution!! THANK YOU!! 🙂
Such a massively helpful tutorial which seems like such an easy task. Had a nightmare with this for a while being forced to boot in CSM for months, thank you
I'm in same boat lol
Thank you. I have been upgrading older MBT systems with new motherboards that only support EUFI and spent days reinstalling windows and program files. I can't believe this 2 minute fix not only exists, but was already located in my Windows directory. I watched a dozen YT videos telling me that this could not be done without having to re-format drives... WOW!
Hours of research and you just completely helped me out within 5 minutes. Thank you!
THANKS, I was actually struggling to update my Windows 10 pc to Windows 11, and this video helped. I went through a lot of troubles not knowing this easy step.
My motherboard is a ASROCK b450M STEEL LEGEND, and once you turn on secure boot, it will loop back to the bios. Turns out what I needed to do is to convert it to GPT first and its all done.
Thanks for making this video. This will truly help me convert a hard drive from MBR to GPT with ease.
I cant like this video more. After dozens and dozens of forum post, Micro$oft SOPs, and googling nothing was working to convert my SSD till I found your video...thank you so much for this quick and simple guide. Much appreciated.
Watched Oct 19th 2022. This works. You may have to check your manufacturer for UEFI change instructions. Need this for Resize Bar.
I want to do this voor resize bar/SAM, what do I need to look out for before following this video?
You saved my life. 10 hours of dealing with this yesterday to no avail. This is THE tutorial video to watch if your windows 11 check finds that you cannot upgrade and has a boot issue. Took me hours to diagnose that my SSD that had windows 10 installed was the issue. You’re a life, and headache, saver! Cheers
Thank you so much! I have been trying to understand why my secure boot is unsupported for hours and came across your video. It instantly worked. Very good at explaining!
Oh, thx man) I couldn't start SAM with 5600x and 6600xt, I was ready to reinstall windows, but then I found this video, thanks a lot bro)
Unfortunately you showed only the trivial part of the conversion, that means when everything on the MBR partition is ok. The interesting part comes, when the validation reports errors. Hope you bring this up in a later video. (restoring WinRE paths etc. if you know what I mean)
That's what it is showing me. What does this mean?
@@AppySaid What exactly does it show you?
@@lonzodaman Disk layout validation failed for disk 1
@@AppySaid If the disk is already GPT you get this error. Make sure, if the disk layout is MBR or GPT.
@@lonzodaman Hello i have the same problem as lonzo. i have this:Disk layout validation failed for disk 3 (disk 3 is my os) How can i pass this step?
I actually blundered into this fantastic tutorial 3 months too late. My gaming PC died and due to other issues I wound up with a "refurbished" Dell Optima 9010 that was setup to run in "Legacy" mode. It has Win 10, a SSD and an HDD (2 tb) so I decided to use it for gaming.....
When I installed a video card is when the problem was apparent.
I did manage to convert it, but I did it the hard way, and made another partition in the SSD "C:" drive. After changing the boot sequence to UEFI I was able use this PC for gaming.
Very clear, very concise, I certainly wish I had seen this before I went through all the hell I went through....
Great video as always! I've got a question: is it possible to follow your video if I have two partitions? One for Windows and another for programs, games, etc. Thank you!!
Absolutely awesome!! I've been looking at this video for a while now lol and nervous to do this, BUT this worked flawlessly, and I have ALL my data! Folks looking to do this just make sure that your motherboard supports UEFI. Now I can update to Windows 11 at some point.Thank you so much Sir!
You are a life saver man, saved me a lot of time. From Philliipines 2024
Absolutely Mega!!!!!!!!!!!!!!!!! Followed instructions step by step and was able to upgrade to Windows 11. Been trying on and off for 18 months. Thought id come to the end but then found this video. Many thanks!!👍
My mind is blown that it was this simple. The Microsoft website was saying I would have to completely wipe my drive! I did this on my lunch break. Finally upgrading to Windows 11.
Britec, awesome as always. I need to do this so i can enable AMD’s smart access memory function. researched all day until i found this video. I’ll perform this as soon as I get home.
You sir, are a legend. This is a brilliant piece of info, shame on all those companies charging money for a tool to do this.
Really the best Tutorial for converting a disk from MBR to GPT. Since I was following your instruction exactly step by step, I made the same error as you did. But then it worked out perfectly. Thanks a lot.
I converted with partition assistant it worked well
THIS IS THE ONLY TUTORIAL THAT HELPED. EVEN MICROSOFT COULDN’T HELP ME.
Excellent stuff 👍🏼. Worked a treat! I was considering buying software for this. Thanks to this video I was able to do the conversion in a very simple way with no poblems whatsoever.
100/10 amazing video thank you so much ive been trying to enable resizable bar for months and this finally helped me do it. Wonderful video super clear and straight to the point.
Thanks for the video it helped me get my Windows11 up and running. Thanks again and good work.
Thank you sir, it's really work ❤
Very useful to get resizable bar working, thanks so much!
It took me a loooong time to figure out that MBR the problem. Your video is AWESOME!
Thanks for this tutorial. I needed to go to GPT as the penultimate step for my pc on the journey to Windows 11. I had spent a few hours on other tutorial methods but none had worked and was beginning to think I would have to shell out for a new pc. I was surprised it could be so easy.
I still have to replace the CPU with one on the MS list and maybe some ram but that will be far cheaper than a new one.
Fantastic tutorial. No ads and all business. Thank you.
Just wanted to say a big thank you this worked for me.
WHERE HAS THIS BEEN ALL MY LIFE???? Thanks a lot for this.
You are a genius. I cannot thank you enough, this was very simple to follow your instructions. The hardest part was hitting the ENTER key to convert it. I am very squeamish about making changes that cannot be undone as well as changing my BIOS configuration but everything worked out perfect. Thanks again!
This was Awesome! Thank you I keep trying different ways to upgrade to windows 11 and this was the key!
THANKS A LOOT !!!
Never new that I have MBR instead of GPT and I struggle to fix it but in vain... until I saw this video.
Now I can update to Win. 11
So let me get this straight. If I do this and I don't have UEFI (unlikely, but still) at next reboot my system is dead.... right? And since the conversion process is not reversible, as far as I know, I would have to reinstall windows to get my personal data back, or call a friend. Don't you think this tutorial should have started with a warning check of some kind for UEFI option in BIOS?
you got it why bother with widows at all
@@jtzoonie2552 hey, why not be a little more constructive with your reply? Not helpful at all. I agree with @GRsBlue BiHan, with the OP stating some "warning check" for those of us who didn't know.
ikr??
No. You should be able to backup your Boot drive prior to conversion using software that allows you to recover your system by running recovery software from a USB boot drive (eg: EaseUS Todo Backup), convert back to MBR, then restore your partition.
Yeh, maybe add a check at the beginning to make sure BIOS supports UEFI. Mine tells me on boot up.
THIS video THIS is the one I needed.
I was struggling with this for 7 hours straight and you fixxed it for me, thanks a lot 🙌🏽
Thank you so much my guy! I finally got my Asus TUF X570 Pro (WiFi) to upgrade to Windows 11 (issues with Secure Boot) after a lot of back and forth with Asus Support and you made it happen for me. You’re the Best!
Microsoft is lucky to have Britec on their side. I went to a number of sites. Last night PC health check said I was ok to get W11 (but not yet - I guess Microsoft had to sleep on it). This morning I got the ok. (subscribed and thanked).
Mate you are literally a lifesaver!! Thank you so so so much. I’ve been trying to solve this problem for two days 🙏🙏🙏
This video helped. I can now use resizable bar on my 3080TI. Thanks. For some reason, i installed windows 10 in legacy mode, but thank god i didn't have to reformat to switch to uefi.
Cool to see u back Brian. i hope ur ok
90% better
@@Britec09 cool beens. and u have great pc videos / they have helped alot. i actually had A problem with my dad's computer the OS would not go in on a particular hard drive so apparently there must be a virus or something out there that can convert GPT to MBR because I think I got a virus it actually converted to car drive back to MBR and I had to use Aomi partition manager to convert cause I didn't have these commands that you have
@@Britec09 where is 10%
Great instructs on how to convert your MBR? to GPT?, except what they are & why we even need to do it?
Which is better GPT or MBR?
GPT is better if you are planning to create more than 4 partitions. We have said an MBR disk can hold 4 primary partitions at most while a GPT disk supports up to 128 primary partitions in Windows, so you can choose GPT if you want more partitions.
Is GPT faster than MBR?
The final result, Compared with booting from MBR disk, it's faster and more stable to boot Windows from GPT disk so that your computer performance could be improved, which is largely due to the design of UEFI.
Is MBR or GPT better for gaming?
For gaming you will be fine with either MBR or GPT (though I personally would go with GPT). Basically speaking it is only in situation when you would like to have a partition bigger than 2TB, or when you would like to have more than four primary partitions, that you need to use GPT.
All the best, Leo. :)
@@invidios My system (asrock450m pro4 motherboard) fails the win11 test without conversion to gpt. Something about secure boot. So I converted.
@@lsimpson50 Yeah, i know. (sadly) Slowly, "they" forced us to upgrade components "for these" times. :D Every WINDOWS version has weakness and strongs. Btw, two of my PC's cannot accept Win 11.(tested with PC Health Check -> "This PC can't run Windows 11" :P Goldies but too oldies :)))
p.s. Minimum system requirements: UEFI, Secure Boot capable.
@@lsimpson50 why update to win11, there is no new software there, it is just some design improvement.
Thanks a lot! I was at a loss but this totally solved it. The post validation failed for some reason (no typo or wrong disk) but nevertheless it works and enabled secure boot. 👍
Thank you so much for clear and fast guide! My drive is now converted without Windows reinstall.
This is the best and clearest video on converting MBR2GPT!. Great work!
sup! I don't sub to anyone for specific reasons, but you have really good stuff my guy. I have seen several of your video's and they are always spot on! Respect! I found you this time because I needed help.. don't tell anyone... for the life of me I could not remember how to convert without losing data and you came through with a solid video.. Take care my man, you have the support.
Thank you for posting the video. As suspected, the process is simple. I just needed the right steps to follow.
This video is exactly what I was looking for, it was clear and easy to follow. Thank you!!
The best video out there on how to convert from mbr to gpt. Thanks!
It worked and no data loss. Thanx!
I could not ever thank you enough for the help you have given "me" with your videos. Thank you again.
Thanx... didn't knew this....you saved me making bootable usb for mbr partition every time i came across old MBR system.
Thanks! CMD is intimidating to many and probably get turned away, but everyone should be watching this video.
It worked. Now i have the windows 11 installed. Thanks dude.
Thank you very much! This worked perfectly for me. I made a backup of my documents and drivers just in case, and I was sweating with fear before I press the command lines, but I am glad it worked. Now I have a GPT drive. Thanks a lot! New sub!
Did it erase all of your data ?
Anyone getting this (and have a solution):
On the validation step, I get this message:
Cannot find OS partition(s) for disk O
Disk 0 is my 'C' drive where I have Windows
Me too buddy. Dont know how to solve
helpa me
Great tutorial - easy-to-follow instructions! Exactly the fix I was looking for!
Amazing! I havent been able to but enable Secure Boot because of that.
Any ideas what do next? Mine says Disk layout validation failed for disk 2
Why can't Microsoft simply add an option in the Windows 11 installer to automatically do this conversion?
One word of caution should be given to old timers like me that have older systems that have ONLY BIOS and NOT UEFI.....DON'T DO IT or you will NO LONGER be able to access your hard disk!! Be sure your system actually has UEFI capability before you convert as I saw the warning when you converted that the process IS NOT REVERSIBLE!! 😨😬
Nice video, by the way! 👍👍
bro which motherboard do you have ??
@@creeperawwman271 I actually have an old ASUS P6T Deluxe V2 as one of my main boards. It's an oldie but goodie! I also have numerous retro machines besides as well! I also use an ASUS GTX 780 ti with the P6T board, another oldie but goodie. I may also use a Sapphire Nitro+ RX 580 with an older Dell Precision T1600 soon. The only thing with that one is is that it does not fit in the case so I got a PCIe adapter cable to use it outside of the case. Also waiting on some even older GPUs' (HD 7770 & 7750) that I bought to arrive for some older (2009 or so) machines. We old (AND poor!) dudes take what we can get! Be well!! 👍👍😀😀
Thank you a lot, You made this so clear and simple. I love you!
Not seen anyone with this issue but here is how I fixed it:
If you load your pc and it says "no operating system found" or something along those lines, then all you have to do is go in bios and it might ask you to press f1 to setup, then you can just go to boot>secure boot>uefi and then exit and save and it should be all good
Thank you so much man! Your teaching are so straightfoward!
worked great for me during prep for W11
on my pc it works like a charm without having to lose any data. thank you!
This worked for me, going from Windows 10 to 11. I had to disable the CSM in the BIOS to take out the Legacy Boot Mode (Z370P Motherboard).
I had a feeling this video would be coming soon
lol you know me to well.
You are an absolute lifesaver, thank you so much for this easy to follow guide!
will not work for my disk, i converted with aomei then
Finally! I converted my OS disk from MBR to UEFI! my heart never beats so hard and fast while doing it lmao now my problem is how to do the same to my MBR HDD
Great tool for System Engineers. Thanks
happy days simple concise instructions on something that was driving me crazy cheers
Such a useful video, really clear, and solved the problem easily. Thank you!
Thank you so much!!! This worked absolutely perfect! Now I can enable Resizable bar!!!
What a lifesaver seriously detailed and precise thank you so much
After searching and watching few videos without successful. This video REAL super helpful, clear explanation and l managed to convert to GPT from my D.I.Y computer Window 10(only a less year old P.C). That the only thing left to setup. Thank You so much 💓.
Thank you so much man this actually helped heaps
can you help me with a question, can I move the os to ssd but leave the data on hdd?
it's been months but yes, I've moved my os to my new ssd and kept old files from my hdd. It was a hefty process though
Hello, I am trying to do this but it keeps telling me "Cannot find room for the EFI system partition conversion failed" please tell me how to fix this I don't know whats going on, thank you!
hey did you find a solution yet?
thank you thank you thank you!!! I watched 7000 videos before yours, and it worked with you :)
This worked great thanks. All I needed, now I can upgrade and microsoft can quit bugging me about win 10 support being removed!
I converted with aomei partition assistant because diskpart is not working for system disk
Isn’t it not free ? I tried and I needed to pay because the demo wouldn’t do the conversion.
It's always been free though and without mbr2gpt!
Open CMD with admin privileges
> Disk part
>List disk
>Select disk X
>Clean (or don't clean if OS drive)
>Convert to GPT
>Exit
remember coming across this MBR GPT with SSD Drives when changing old HD to SSD
Yeah, I had to clone an old HD to an SSD and had a considerable amount of trouble with it insisting on using GPT. I had to use EaseUS Partition Master to get the thing to clone the original MBR to the new SSD as a MBR. The system wouldn't boot to the clone unless I did that. Everyone expects you to have new systems that are going to be GPT based.
I always get "Disk Layout Validation Failed for disk 1" which is may C: drive. A samsung SSD
same but its disk 0 for me
What did you do?
@@faizanshaikh7024 reinstalled windows and converted disk while installing windows that helped me.
Thank you for this video, short and directly on point :) It worked great for me.
Britec09, you are a genius and so utterly helpful. Thank you for all your informative tutorials - you're a God send.
You solved the problem for me as well, I absolutely love your how to videos
NO BS, this guy is awesome!! worked for me
Wow this is all I needed, I'll let you know if it works after I reboot lol. Thank you so MUCH you saved me so much stress and agony.
Thanks, I tried for weeks to find out why I couldn't switch from mbr to gpt, bcos I never had a partition, or it couldn't be found, I stumbles accross something I tried, which fixed it, and I had to rebuild my BCD file, after I rebuilt that, I tried to convert to gpt, and it worked first time, thanks for this video too.
Thanks mate! After spending some time figuring this out, i finally found your amazing explanation video. Cheers
I'm glad the video helped. Don't forget to hit the subscribe button
So I converted the disk and plan to move the os to ssd so I can boot from it and save other data on hdd, I cloned successfully with partition assistant.
Great video! Easy to understand directions! Thank you!
