Dell PowerEdge R440 install fails: no ISO found

[gurubert]

Hi,

when booting the PVE 7.1 ISO from an USB stick the ISO cannot be found:



In the end it bails out with the error: no device with valid ISO found, please check your installation medium.

This is already the second USB stick tried.

A Debian 11 installation on the same machine works without issues.

hi,

how did you write the ISO to the usb?

can you tell us about your hardware?

if for some reason it doesn't work but debian does, then you can also install on top of that [0]

We did install Proxmox on top of Debian 11 and then rewrote the USB stick with dd from there.

On the next machine it worked flawlessly.

I have no idea how it failed the first time.

different hardware or the same?

how did you write the usb the first time?

That was on the same hardware. How the USB stick was written in the first time is beyond my knowledge as it was prepared by my customer before the workshop started.

The error was just odd that it was able to boot but then not find the rest of the ISO. Strange things happen.
