Hi,
I'd like to share what happened to me today, hoping that it will save others some sweat.

I installed Proxmox VE from the latest ISO (currently 9.0-1) after booting it through Ventoy.
The installed system could not boot; I got a purple screen with the following message:

KERNEL PANIC!
Please reboot your computer.
VFS: unable to mount root fs on unknown-block(0,0)

I finally found the root issue: the installer carried over to the installed system a kernel parameter that was clearly injected by Ventoy working in GRUB mode:

linux /boot/vmlinuz-6.14.8-2-pve root=/dev/mapper/pve-root ro rdinit=/vtoy/vtoy quiet

the rdinit=/vtoy/vtoy parameter was clearly the culprit.

I actually found some reference to this issue, along with a resolution, on other threads. But I decided to post this anyway.
I'm not 100% sure, but if I got everything right, this may be an installer issue that may be addressed.

Happy hacking, -a
