Question about restoring a system backup

edited February 2016 in AOMEI Products Support
Is it possible to restore a MBR disk sustem backup file to a GPT formated disk using AOME backuper?

    Yes you can restore. But I doubt you can start it.  MBR=BIOS while GPT=UEFI. So you try to start with UEFI a BIOS installed operating system. That will result in an error of missing system32\winload.efi. 

    But you can try to change UEFI in legacy boot (first set secure boot off) than it may start, but I think that the GPT in that case should be converted to MBR first before restore. That is an option in Disk management but only available when all partitions are deleted.

    Or use Aomei Partition Assistant (Pro?) to convert MBR/GPT

    it depends on the computer you have BIOS or UEFI firmware, not exactly on the disk. It is easy to convert a GPT styled disk to MBR style, but firmware should be BIOS to make sense.

    Here are the diskpart commands just in case, and the disk will be empty in MBR style

    list disk (and your GPT disk has a * in the last column)

    select disk n  (where n is the disk in question, make sure it is true).

    list partition (this is to verify it is the right disk, has the right old contents)

    clean

    convert mbr (this is optional, as clean makes it automatically mbr).

    exit

    when you have UEFI firmware, one needs to create the three hidden windows-and-firmware-related partitions yourself. This is possible but involved. Then restore just C: and WinRE (if you have) and run more commands to make that disk bootable and WinRE working.

    Yes, you can do it. But when you finish the restore, you need to amend the boot mode.

    MBR=Legacy and GPT=UEFI.
