Error /boot/ USB installation Proxmox 9.1

[uniketou]

Hello all,

I've build a brand new server and I want to install Proxmox 9.1.

I've prepared the USB stick but I got the error below : error : file '/boot/' not found



=> ISO Checksum is OK (downloaded twice)
=> USB configured with : Rufus (dd mode) or Etcher : same issue
=> tested with PROXMOX 9.0 : same issue
=> tested 2 USB stick : same issue
=> tested on different USB port : same issue
=> Secure Boot disabled

Installation is done via IPMI (no monitor connected).

Motherboard : AsRock Rack ROMED8-2T
RAM : 128Go ECC
CPU : EPYC 7713
Graphic : AMD RX 9700XT


Have you any idea ?


Below some BIOS screen :

- 3 SSDs



- 2 Nvme :



- IOMMU Enabled :



- Boot menu (tried with 2 differents USB stick)

I think i got this message too when installing PVE 9.1 but after a second the Grub Boot screen showed up anyway. You could try nomodeset or hook up a display to your GPU or remove the GPU, install PVE and then reinstall the GPU. Not sure if IPMI works correctly when a discrete GPU is installed. Maybe the PVE installer outputs to the GPU instead of the integrated IPMI GPU?

For nomodeset ; how to set it ? because I don't have access to proxmox (even the menu for the install is not displayed).

Or I'll test to connect a monitor on the GPU to see what happen.

Thanks !

Maybe there is a bios option to disable the dedicated GPU for now? Reenable when pve is installed. Or something that lets you select the primary GPU?
