corrupted Virtual Machine

[mlopezbialet]

Due to a power problem, the proxmox server was shut down by surprise.

After restarting it, all the virtual machines worked ok, except one with Ubuntu.
This starts in a loop, not knowing the content of the hard drive. the format of the disk is raw, and I have not been able to repair it.

I ask you to tell me how I could do it, since the 4 backups don't work either, I don't know why.
backups are vmz.zst files.

From already thank you very much

Hello
Maybe you can load a .iso of a live CD/DVD whose purpose is repairing and boot on it instead of your hard disk.

Once your VM started with this LiveCD you can use tools to repair corrupted boot record or partition setup.

Thanks for your answer.
I already used an .ISO, but I couldn't recover the partition information. The LiveCD recognizes a partition, but cannot find the data within the partition.
Do you have any idea how to recover the data? the 4 backups that I have, are with the same problem.
Thank you..!!
