#UEFI DISK MAP HOW TO#
TODO: add a short walkthough explaining how to resolve this kind of error Solution (temporary)ĮDIT: This is a manual way of doing it, you can actually use the UEFI menu to create a new entry.Īs in most shell, scrolling is shift+ pageUp/ pageDown. The boot entry stored on the EFI NVRAM (persistent storage where the UEFI configuration is stored) didn’t point anywhere, and the boot process failed flat. The error was likely prompted by a change in the PCI bus or storage (virtual) card topology ( 1). This particular VM is configured to boot using a VirtIO SCSI controller. The VM then proceed to try to boot using PXE, fails, and eventually drop into an EFI shell: The error reads BdsDxe: failed to load Boot0001 "UEFI QEMU QEMU HARDDISK" from PciRoot(0x0/Pci(0x1E,0x0)/Pci(0x1,0x0)/Pci(0x5,0x0)/Scsi(0x0,0x0): Not Found.
