Issue with Windows Server Recovery on Hyper-V using UrBackup

Restore
1

Hello, I am using the recovery ISO urbackup_restore_2.4.2.

I have image backups of 11 Windows Servers and periodically perform validation tests for these backups by restoring them via a virtual machine in Hyper-V.

This month, via UrBackup, it installed and recovered all the machines; however, two of them open the Windows repair screen, and even after performing repairs via SFC, chkdsk, using a bootable USB drive, and even recovering UEFI or BIOS for these machines, they still do not boot correctly. It is possible to access them via file normally, but not a full recovery of the virtual machine in the VM.

In the UrBackup restore logs, there are no anomalies or restoration problems.

One of the machines is a Windows Server 2012 R2 with a 2TB disk and CSM/BIOS boot technology.
The other is a Windows Server 2019 with a 1TB disk and UEFI boot technology.

Do you have any suggestions on how to debug what is causing the two machines to go to the Windows restoration screen?

Do you need any more data to help debug the problem? Thank you in advance.

I also remembered to say that these machines previously went up normally in other backups, however in the most recent and in the oldest ones (available in the restore) they no longer work.
As what worked was left behind because of the backup limit, I can no longer use it to validate if the problem also occurs.

I hope this information is useful. Thank you.

Does anyone know anything that could help me?
