after import .ova files in VMM back: Booting from Hard Disk...

[eddy007]

Hello dear forum members,

after a long search in the net, I have unfortunately not found a solution to my problem.
I very much hope that someone can give me a helping hand or suggest a solution.

I am using a DS920 + with version DSM 6.2_below I bought new 4x 4 TB disks.
First, I backed up my NAS using Hyper Backup. When backing up I saw that my VMs were not there in the VMM.
I then exported the VM's all individually in the VMM to an external USB HD as an .OVA file.
After importing the OVAs, many of my virtual servers no longer start.
Only this black window appears with the message “Booting from Hard Disk. . . ".

I don't understand why only 2 servers start: a VM Windows 2019 Server and a Linux Debian Server.
Not all others (Debian / Mint), only with the message “Booting from Hard Disk. . . ".

The compatibility mode for the CPU was switched on, but did not lead to success.
And the BIOS setting in the VM: UEFI also didn't work.

Maybe someone has an idea what it could be? I'm really desperate .....
Thank you & best regards

Guessing you have tried these options already?

As well as made sure that the boot from is set to virtual disk?
