Proxmox 6.1 No cdrom found w/ USB but previously successful

[cr0n_dist0rti0n]

Created the install USB on Ubuntu 18.04LTS with DD instructions on: https://pve.proxmox.com/wiki/Prepare_Installation_Media

Booting on:

Asus Z9PA-D8 with dual Xeon E5-2670
32GB Ram
10 HDDs connected

The interesting bit is I just installed Proxmox and it was totally fine. Booted fine and started working with it. Then I rebooted my server and I got the following message:

Cannot process volume group pve
Volume group "pve" not found
Gave up waiting for root file system devices.
- Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/pve-root does not exist. Dropping to a shell!


BusyBox v1.30.1 (Debian 1:1.30.1-4) built-in shell (ash)
Enter 'help' for a list of built-in commands

(initramfs)

I researched this and could not find a solution. So frustrated I was like "I'll just reinstall". Then I went to boot from the exact same USB drive that i had installed with and received the following error:

Proxmox startup

This message was from booting into "debug mode". Exasperated i tried a new flash drive and DD'd it. So I have tried two separate flash-drives with the exact same result.

The interesting bit is the drive is mounted on all boots with both flash-drives. Please see attached picture. I have gone through a lot of the forums but have not found a solution which work. I have been running FreeNAS for a number of years but was thinking about moving to Proxmox and virtualizing FreeNAS as I would like virtualize and see how that goes; sadly not so well yet.

I am perplexed how the first run Proxmox did everything perfectly and now for some reason its not. I would still very much like to try out Proxmox and see if its something i would like to deploy on a larger scale. Hope there are some ideas.

Hi,

this problem are BIOS/UEFI related.
You can try the following things.
1.) Try to update the Bios firmware.
2.) increase the "rootdelay=" to 5sec. This can be set on the Linux boot parameter. in Grub menu, you can press e
3.) install Proxmox on top of Debian 10.[a]
4.) wait for the new Proxmox 6.1-2.iso
