[SOLVED] Physical2Virtual: Windows Server 2012 R2 UEFI/GPT on PVE 7


Mar 25, 2021
Dear Proxmox Community,

last night I had to migrate a Physical Windows Server 2012 R2 x64 UEFI/GPT Server to Proxmxo VE 7 (for a customer, we already use Proxmox VE Enterprise).
I tried many different things but in the end the virtual Windows did not start.

Here's what I tried
  1. Installed Proxmox VE 7 on new Server (Community Repo for the customer for starters)
  2. Shut down Windows Server 2012 R2
  3. Boot Windows Server via CloneZilla
  4. Created VM in Proxmox VE 7
  5. Cloned 2 Disks (300 GB + 1TB) to new Server via CloneZilla
  6. Tried to boot new Server -> Failed
When starting the server you can see the "Windows is Loading"-Circle at the bottom (see Screenshot of Boot).
It also states the following:

BdsDxe: failed to load Boot0001 "UEFI QEMU DVD-ROM QM00005 " from PciRoot (0x0) /Pci (0x7, 0x0)/Sata(0x0,0xFFFF,0x0): Not Found
BdsDxe: loading Boot0004 "Microsoft/Boot" from HD(2,GPT,54B26639-AEFF-46A3-9BF0-CF0DDF98EE93,0xAF800,0x32000)/\EFI\Microsoft\Boot\bootmgfw.efi
BdsDxe: starting Boot0004 "Microsoft/Boot" from HD(2,GPT,54B26639-AEFF-46A3-9BF0-CF0DDF98EE93,0xAF800,0x32000)/\EFI\Microsoft\Boot\bootmgfw.efi

As far as I understand this, it means "Booting from DVD not successfull" (that's ok, virtio Drivers ISO is in there).
2nd and 3rd row seems to say "Found Windows UEFI Bootloader, Booting ...", is that right?

Problem being, after this and the circle at the bottom spinning for a litte while, Windows does not Boot but I get a Blue Screen (looks a little like the new Windows 10 BSOD, but it's gone too fast to read it).
Afterwards, Windows boots into Recovery mode (automatically, no ISO inserted, so the disks are recognized as the recovery mode is on the "hidden" first partition).

In Recovery Mode I tried using "automatic startup repair" (doesn't work).
Then I tried the commandline in recovery mode to see if there's something wrong with the disks/partitions, but DISKPART does not see any disks (list disk is empty and list vol only shows the DVD).

I also tried cloning the disks via Microsofts disk2vhd, but that cloned image just booted directly into UEFI shell.

There are only 2 things I could think off the top of my head to try:
  • VMware standalone converter
  • Boot from Windows 2012 R2 ISO and try to restore from Backup (USB Disk Baremetal Backup created via Windows Server Backup)
Windows Server 2012 VM Config
Please disregard the scsi2, that's the disk2vhd image I tried to boot afterwards.

I hope one of you can point me in the right direction, as I really do not understand why Windows does not boot, even though recovery mode boots (from the disk which DISKPART does not even see).

Thank you very much for your time and help.

Best regards,

Dear Proxmox Community,

I deleted the VM yesterday, created a new one and booted from Windows 2012 R2 x64 ISO to restore the latest Windows Backup.
This worked and the VM is now up and running!

For the restore to work, I had to change the Disks to IDE.
Even when installing the correct drivers (with virtio-iso) inside the Windows 2012 R2 ISO Recovery Mode, it did not see any disks.

For anyone interested, here is the new VM config:
agent: 0
bios: ovmf
boot: order=ide2;ide0
cores: 8
efidisk0: local-lvm:vm-100-disk-1,size=4M

ide1: local-lvm:vm-100-disk-2,discard=on,size=1T,ssd=1
ide2: none,media=cdrom
ide3: local:iso/virtio-win-0.1.185.iso,media=cdrom,size=402812K
