Hello,

I made a change to the hardware settings of a windows VM which has iGPU passthrough and which I am using concurrently as my desktop and my proxmox server won't boot.
I am getting the dev/mapper/pve-root stuck screen.

I am thinking that maybe I can reverse out the setting in the .conf file by mounting the entire proxmox nvme root disk.

I have tried to put the whole nvme onto a 2nd slot of another Proxmox server. I can see the NVME partitions 1,2,3. But when I mount it in the shell it just say it is an EFI partition.
Is there a way 1) basically get the promox to boot into some sort of safe environment 2) I can access the /etc/pve something directory by mount the correct partition to edit the conf file of that Windows VM?

Thank you so much. Please please help!
 
Yes thanks for the confirmation. I managed to boot in a proxmox rescue environment and yes that directory is completely empty. So I am stuck.
Is there a way to boot back into the proxmox? I am desperate.

But since can edit the root directory. Maybe I can disable all the VMs? Currently the Window VM is set to start upon boot (and thus it boots into Windows I can get the HDMI output and use the kb and mouse as a desktop).

OK I solved it by googling a bit. Somehow even though the screen isn't booting into Windows, Proxmox did boot up. I managed to get to the web interface and disable the device in the Windows VM hardware settings. Now back to normal.

That was so lucky.
