Issue installing PBS on Hyper-V "No device with valid ISO found"

[florianlkm]

Hello,

I am trying to install PBS on a Hyper-V virtual machine.I can successfully boot from the ISO, but then I encounter the following error: "no device with valid ISO found".

Here are the details of my configuration:

• VM Generation: Generation 2
• Storage: DVD drive attached to a SCSI controller
• ISO Integrity: I have verified the hash of the ISO; it is not corrupted.
• ISO Location: Stored on the Hyper-V local storage.

I also tried with a Generation 1 VM; the installer proceeds further, but I eventually run into the following error:

Did you try using the TUI installer instead of the GUI installer? Also, as a workaround you can install on top of Debian Trixie as described in https://pbs.proxmox.com/docs/installation.html#install-proxmox-backup-server-on-debian

Yes, I tried in TUI mode, same issue. I'm going to try installing on top of Debian

I got this problem as well - could be a hinder to anyone using Hyper-V. installing from Debian seems like a decent workaround..

I hope this is "flagged" as a bug with the maintainers as not having your .iso supported by a major virtualization platform could hurt adoption.
