Arch Linux ISO boots via BIOS, fails to boot via EFI

[mpb]

On an Intel NUC, I can use Ventoy in BIOS mode to boot the Arch Linux installation ISO.

If, on the same Intel NUC, I use Ventoy and EFI mode, the boot will fail.

The failure messages is:

Waiting 30 seconds for device /dev/disk/by-label/ARCH_202010 ...
ERROR: '/dev/disk/by-label/ARCH_202010' device did not show up after 30 seconds.

I then get an emergency shell, and I can see the following devices in /dev/disk/by-label:  Recovery and VTOYEFI

Recovery is probably Windows 10 on another disk.

If, instead, I boot via BIOS, the following disks exist in /dev/disk/by-label:
ARCH_202010, Recovery, and VTOYEFI.  ARCH_202010 is a symlink to /dev/dm-0.

Attached are screenshots of (1) the EFI error message, and (2) ls -l /dev/disk/by-label after a successful BIOS boot.

I don't know if it would make a difference, but the partition that holds all my ISO files is formatted with ext4.

In the shell, please run cat /ventoy/log

It's a bug and has been fixed and will be ok in the next release.

Please try Ventoy-1.0.23
