When I start the VM I get errors:
Code: Select all
BdsDxe: failed to load Boot001 "UEFI VBOX CD-ROM VB1-1a2b3c4d " from PciBoot (0x0)/Pci (0xD, 0x0) /Sata (0x1,0xFFFF,0x0) Not Found
BdsDxe: failed to load Boot002 "UEFI VBOX HARDDISK VB414d6f67-39ddec9b " from PciBoot (0x0)/Pci (0xD,0x0)/Sata(0x0,0xFFF,0x0) : Not Found
BdsDxe: No bootable option or device ws found.
BdsDxe: Press any key to endre the Boot Manager Menu.
Note that this is NOT a new attempt to install a Windows VM. This VM has been running for quite a while. I've just now updated the Linux host for UEFI. The Windows VM has been running with a CSM/MBR Linux host all this time and I am trying to now get the Windows VM to boot UEFI. If I turn off the TPM and UEFI settings for the VM it boots per usual.
How do I get the Windows VM to boot UEFI?
