EFI / BIOS changes

These are the steps need to boot disks when the source hypervisort (in my case hyper-v) was using EFI and GPT disks.

Note wether the OS is Debian, Ubuntu, etc or Windows these steps change - the main difference will be step 7 and the name of the efi file. You will only need to do this if the OS has been install on a source hypervisor where EFI was enabled on VMs (e.g. gen2 VMs on Hyper-v)

Steps

1. boot and entio bios to change UEFI order click in console as it says bootin and mash esc key until you see:

   

2. select boot maintenace manager above

   

3. then select boot options.

   

4. then select add boot option

   

5. then select the boot volume (if you did step 8 right there will be only one)

   

6. select EFI

   

7. select the OS (in my case debian)

   

8. select the right EFI file - in my case either grubx64.efi or shimx64.efi will work, i go with grubx64.efi

   

9. add a description - anything will do, just rememebr it

   

10. commit changes and exit
