[@Francoisdp82]

[@JudeAdigwu-k7m]

i have been wasting my whole afternoon and i almost gave up until i found this. Thanks man

[@The_Waraba]

Your video was a time saver! Thank you.
Same issue on Hyper-V running on Windows Server 2022.

[@rmo9808]

And 2019

[@roseannemaepunzalan6697]

Oh my.. I wasted too much time trying other steps, this is amazing, finally save me 😊😊😊 thank you so much

[@JackLucky777]

Thank you for your video. I spends three hours to solve this problem until watching your video.
There are two key points I have organized.
First, if you using a Generation 2 VM, having to add a TPM option, and if not, showing the error that windows' system do not suit basic needs.
Second, while your boot windows system, you need to continuously press any button on the keyboard immediately within one second before showing any words on the screen, otherwise the system must be wrong.
Overall, these are my experience at this time.
I hope everyone can be solved, good luck!🥰

[@michaeligbuan2781]

Thank you for the video, wasted hours trying other fix, before finally getting this fix.

[@Espi68One]

Thanks for the Great Vid, building a Virtual Lab for CySA and had been fighting this for about an hour.

[@seadmiljkovic3870]

Danke!

[@OnlineComputerTips]

Thanks for the tip!

[@gopartay]

Many thanks. If only Microsoft was smart enough to address this in thefirst place.

[@roysparky1858]

it's 2024 and it still works! thank you so much!! ❤❤❤❤❤

[@nathanwesterman6158]

I have literally wasted half a day on this. Thanks for saving my afternoon!

[@rmo9808]

2 HOURS! It took until I found this. I'm trying stuff out before a new job and I usually use virtualbox or proxmox. This is why I hate Microsoft.

[@headlesmouse]

As everyone else has said. Wasted hours upon hours and recreated VM's about 10 times. Can't believe how easy of a fix this is. To answer your question - YES it does happen on Windows Server, too. I am running HyperV on Win Srv '22

[@kienleong3631]

Thank you! Gratifying to find a simple fix.

[@olumbaizunna9948]

Thank you very much. I have spent almost 6 hours on this before seen your video. Thank you

[@CurlyPotatooo]

Quick guide and solution. Saved us a lot of time, thanks!

[@KennySVG]

You can also hit Action --> Reset at the top menu and press the key quickly then. That worked for me.

[@sm.saadarefin2879]

After boot from cd message I got this error-
"A media driver your computer needs is missing.This could be a DVD,USB or Hard Disk driver.............."
Is there any solution for this error?

[@Kirbyphone]

That is crazy... I legit spent 5 hours trying to find solutions and editing many Windows settings... Turns out I just needed to hold space bar

[@pascal9782]

God bless I found your video! :)) appreciate it

[@ishanvats6289]

It's still there, on Win 11 pro. Thanks a ton for the hack!

[@ificouldsee]

OMG! Simply hold space button down before pressing start. Also, going under action and selecting restart helps. Holding space button then pressing start did it for me.

[@kizmoko1739]

OMG that's just it. So simple. Thank you very much!

[@mluszczynski]

This fix didn't work for me. I made the change in settings just like you did. I then went to hold down the space bar before starting the vm. The space bar happen to start the vm. Then I received the same message again. I am using Hyper-V on WIn10 Pro Version 22H2.

[@RonaldValade]

I wish this worked for me. It seems to boot up WAY too fast to even recognize my keystroke...

[@RonaldValade]

Well, I kludged it. I had to add half a dozen SCSI DVD drives with mounted ISOs to slow it down enough. What an odd bug...

[@MonicaSalas-kc9ke]

You sir are a legend

[@professorx3510]

Love you bro😭😭😂

[@AltaiiSinan]

The "real" solution is that you have to use delayed start so you can have time to press a key. Here is a solution for you having bootloader failed issues
Steps to Enable Boot Delay in Hyper-V:
Open Hyper-V Manager:
Launch Hyper-V Manager from your system.
Access VM Settings:
Right-click the desired VM and select Settings.
Configure Automatic Start Action:
Navigate to the Automatic Start Action section.
Set a startup delay (e.g., 5-10 seconds).
This creates a brief pause during the VM's startup process, giving you enough time to interact.
Restart the VM:
Start the VM, and during the boot delay, press the required key (e.g., F12) to access the boot menu or interact with the setup. (in my case i installed windows server 2025 with hyper-v and tried to install vm with windows server 2025)
