I have a colleague with an EFI Qubes 4.0 installation on a ThinkPad with a mainboard failure. The SATA SSD is working fine but his encrypted external disk used for his backups is corrupted & so has no backups. I have tried booting it another older ThinkPad (T450s) but it is not capable of booting Qubes 4 on EFI & I don’t have any other laptops with SATA drive ports, only NVMe.
Is there any method to either manually transfer the existing VMs or .imgs to another Qubes installation or better still - manually make a Qubes backup of the existing VMs to restore via Qubes Backup on another installation? I have my own working Qubes installation - but it is Qubes 4.1 & other Fedora laptops - & can attach the SSD externally to them.
