windows inaccessible boot device

  • If your guest is Windows, you additionally have to execute the following commands. This example assumes that your imported virtual machine has the ID 130.

    • Use UEFI instead of BIOS for the virtual machine.
    qm set 130 --bios ovmf
    • Windows requires additional drivers to use SCSI. Therefore, use IDE instead for the moment.
    sed -i 's/scsi/sata/g' /etc/pve/qemu-server/130.conf

    This gives you a first working version. You can then improve your experience by installing additional drivers as explained in Windows 10 guest best practices.




  • 1 . Use temporary devices for NIC and SCSI. I have used E1000 and Megaraid SAS, in other cases SATA disks
  • 2. install virtio drivers
  • 3. add an additional disk with virtio SCSI - this was necessary to load / install the drivers
  • 4. after that disk is recognized / installed: shutdown the OS an reconfigure to the Virtio SCSI controller and disks.

  • In meinem Fall, musste ich das Gerät aber wieder auf BIOS umstellen, PXE boottete nicht



  • GGf den SCSI-Controller manuell entfernen
  • a) detach drive
  • b) attceh -> choose ide
