[SOLVED] Can't boot my VM anymore: disk not found?

[sylar12]

Hi all,

After a reboot of my node, one of my VM (running Home Assistant OS) is not booting anymore. I get the error message:
BdsDxe: failed to load Boot0001 "UEFI QEMU HARDDISK QM00005 " from PciRoot (0x0) /Pci (0x7,0x0) /Sata (0x 0,0xFFFF,0x0) : Not Found

I have already found multiple posts with more or less similar error messages, all apparently related to UEFI boot, but I didn't found any clear solution so far.
To be honest, I have absolutely no hints on what's happening ...

Here is my VM configuration:

root@proks:~# qm config 101
agent: 1
bios: ovmf
boot: order=sata0
cores: 2
efidisk0: local-lvm:vm-101-disk-0,size=4M
memory: 4096
name: hassos
net0: virtio=4E:C2:33:89:DC:AA,bridge=vmbr0
numa: 0
onboot: 1
ostype: l26
sata0: local-lvm:vm-101-disk-1,size=50G
scsihw: virtio-scsi-pci
serial0: socket
smbios1: uuid=9e6ce446-6583-4109-ba0b-d53953833608
sockets: 1
usb0: host=0658:0200,usb3=1
usb1: host=1a86:7523,usb3=1
vmgenid: 601dac37-c6c6-466f-a5d3-1d5b76578a0a

I have checked that secure boot is disabled, and also checked the boot order (where the first is: sata0 (local-lvm:vm-101-disk1, size=50G))

Any help would be highly appreciated

Which version of Proxmox VE are you running? If it's pre6.2 it might be a bug. Otherwise it sounds like your partition table might have been corrupted. If you have a Backup/snapshot, try restoring. If not, you should really make backups.
You can try rewriting the partition table with so [1] but take a snapshot first and/or make a backup.

gdisk -l /dev/pve/vm-101-disk-1 to check the table

gdisk /dev/pve/vm-101-disk-1
w

to make a new table.

Again, make a backup before running these commands.

Hi @noel.

I'm using Proxmox 7.3-6.
I did find the same solution a few hours after my initial message and I can confirm these simple commands solve the boot issue.
It seems this is a bug already reported here, at least as far as I understand the underlying problem.

Anyway, thank you very much for your answer!
