Windows 11 guest hanging in UEFI on Linux host

Post by Gunther »

I reinstalled VirtualBox from former 6.x to 7.0.6 with existing Windows 11 guest system.

Windows 11 guest is running as long as EFI is disabled.
If I activate EFI, the boot process ends up in "UEFI Interactive Shell v2.2" prompt. Entering "exit" puts it back to firmware setup.

What needs to be altered to get the boot process running?

Regards,
Gunther

As well as enabling EFI in the VM settings, you must also convert the disk format of your VM from MBR to use the GPT partitioning scheme. A google search of 'windows convert MBR to UEFI' will bring up a large number of links for you to follow.

I think Convert MBR to GPT without data loss looks pretty good.

I would suggest that before trying this you make a full copy of your VM folder while the VM is not running so that you can recover in the case of failure.
