Полный бред, если windows установлена на legacy, значит диск размечен как mbr, а из этого следует что если включить UEFI, то windows просто не запустится, потому что для UEFI нужен GPT диск
I really appreciate you taking the time to post this video. Worked like a champ! It blows my mind this isn't part of the standard Windows 11 upgrade process.
3:05 help, it show "ERROR: MBR2GPT can only be used from the Windows Preinstallation Environment. Use /allowFullOS to override." after i type that first command and "Disk layout validation failed for disk 0" for the second command
@@abosam1362You made sure to do the command line bit in the video? Very important, I did that then switched my BIOS over to UEFI mode and then it appeared.
I usually dont comment on videos so use this as a gleam of hope in case you r not sure about trying it. Was assuming i needed to reinstall Windows and this worked perfectly 10/10. Keep the good work buddy, really appreciate
i think i made something wrong... my pc wont open cuz i have only screen with message "No bootable devices--strike f1 to retry boot, f2 for setup utility press f5 to run onboard diagnostics" i have an dell pc, please someone help
hi, thanks for the video. I have question, under disk mgmt for the C drive, I have "system reserved" partition (system, active, primary partition) and C: (boot, page files, crash dump, primary partition). are both of these ok for me to run the convert command? thanks again!
he said that we gotta make sure that theres no logical partition so it wouldnt interrupt the conversion since a logical partition is a another destination of storage in one drive i used chatgpt for help and i can do this without any problems or worries only worry is if my data might get deleted (you prob gave up on this or took a risk)
Hello ...my hard drive is in the gpt format and i can use uefi normally ..but for some reason when i disable legacy and turn on uefi only ...the uefi bios seems laggy and somehow different than the normal legacy bios .. and also I can't see the manufacturer logo ( in my case hp ) when my pc boots up ..do you have any explanation?
@@elijaharthur8040The maximum number of partitions you can create in MBR mode is only 4. If you want to get fix of the error you will have to delete 1 partition (not recommended).
The only one video that helps me, thanks u so much!
Glad it helped!
Brooo my pc says " reboot and select proper boot devie or insert boot media in selected boot device and press a key" and i cant turn mo pc on. How can i fix this???😭😭😭

Welcome 👍
freaking valorant got me here. this game wants me to do everything from un-legacy my bios mode to give away my firstborn just to play the damn game.
did it work?
Did it work? Same issue here
Faild for disk 0
Not work
Works great you just need to make sure tht the Systempartition uses all available space on the disk and that there's no unused space
Very useful, it save me from formatting my Win 11. The step provided are very simple to follow. Thank you.
Glad to hear that
@@asatechnical Should i convert other disks to uefi via this way? Will it work?
Really worked! Thanks too much bro . Beyler bayanlar pc yi uefi yapıp açamıyorsanız uygulayın bunu gerçekten işe yarıyor.
I tried but windows eeased.
Should i convert other disks to uefi via this way? Will it work?
My PC automatically resets to Legacy from UEFI after each power cuts (No power backup). Any way to fix permanantely to UEFI mode? Thanks in advance.
You are literally a god bro ❤none videos and tricks worked but this one did i love u bro may god bless u ❤❤❤❤
Glad it helped, have a good day
BTW I'm Human🙏
@@asatechnical love u bro 🫂but I need a little help of urs I don't want to use windows and thinking to use some other os now can u give me a guide for that like for prime os or any other which is on ur channel ❤🩹
🎉at first my boot mode was legacy but after trying this method I was switched to UEFI successfully
After 2 months of suffering finally i can now boot my pc thanks alot
how did you do it if you cannot boot it
Have one problem my Pasword does not work when im trying to go in Ofline Cmd
by backup data do you mean backup only from c drive or all drives
In bios settings, I can't find [boot mode: lagecy]
you need to find CSM, there it will be
There is no CSM 😢
@suhanisingh4899 I know the solution
Just buy a new pc
I do it, and it's work it
what if the pc just resets when i try to do the command prompt then what?
this doesnt work on a single drive with no empty partition. this is the SAME as formatting the os from win 10 why

Why you come here to comment without watching the whole video!
@@asatechnical Потому что после выполнения первого шага, windows не запустится. Поэтому нет смысла в дальнейших действиях.
i can't see the disk 1, i only see is CD-ROM 0 and it has nothing
troubleshoot automatically goes to advance option and only shows startup settings
I really appreciate you taking the time to post this video. Worked like a champ! It blows my mind this isn't part of the standard Windows 11 upgrade process.
what if winre needs to be disabled and enabled?
3:05 help, it show "ERROR: MBR2GPT can only be used from the Windows Preinstallation Environment. Use /allowFullOS to override." after i type that first command and "Disk layout validation failed for disk 0" for the second command
Problem is you typed wrong command 😅 1st:- mbr2gpt /validate /disk:0 /allowfullos
2nd:-mbr2gpt /convert /disk:0
Legend! Worked for me, was worried as heck that my PC wouldn't boot soon as I switched my BIOS over to UEFI mode but all is good, thanks my man! :)

No
Works great! 🙏 thank you
Glad it helped!
bhai i have windows 10 motherboard is Asus h310m e r2.0 bios mode shows legacy i want to update it to windows 11 what should i do?
Do you check if your PC's bios supports UEFI firmware?
If not supported, watch our video on how to install Windows 11 on an unsupported PC!
@@asatechnical there is uefi only option in boot mode but my bios is not updated the bios version is of 2019 and the latest bios is of 2022
Try to update the BIOS first and then perform the upgrade procedure!
@@asatechnical same method as yours?
Yes, you can try this method if your PC does support UEFI, and don't forget to take backup of your important data.
Worked, thank you!
Glad it helped
thanks for the help, that was too eaasy

What key did u say 2:07
Sift
I show me failed validation
Check the hard disk layout! Your hard disk should have three partitions to convert
@@asatechnicalhas 4, would love to know how to make it unallocated to fix validation failed
@@elijaharthur8040The maximum number of partitions you can create in MBR mode is only 4. If you want to get fix of the error you will have to delete 1 partition (not recommended).
You need three partitions or less i think
Thank you so much, You saved me.
Glad I could help!
Windows 11 doesn't support mbr partition.
This video is not true
You are dumb
