[SOLVED] Making Windows To Go bootable with Ventoy

[meilon]

@meilon: I haven't tested any of it but you pointed at the problem yourself -- Windows will not boot off an exFAT partition, which Ventoy uses by default.

You need to manually format the first partition of your USB drive as NTFS after installing Ventoy for Windows to boot.

Thank you both! I read in the forum post linked in the issue the very important line (thanks to Google Translate): VHD(X) boot currently only supports dual NTFS or dual exFAT combinations, and does not support outer NTFS+in exFAT or outer exFAT+in NTFS combination.

Now after formatting the Ventoy partition as NTFS at least the system tries to boot from vhdx, but sadly, I can't get any configuration of vhd/vhdx, mbr/gpt and dynamic/fixed to boot completely in either legacy or uefi mode. It always fails after getting devices ready with "Windows could not update the computer's boot configuration. Installation cannot proceed.". Any ideas on that?
