Hello Due to a systèm failure I had to give m'y rig to repair, théy changed mbr to uefi/gpt in the process Can I still use the system backup (using W10 so called "Windows 7 backup tool") I created before the repair when it had mbr ? Thanks
If you don`t want to run uefi there should be an option in your system bios to switch it back to legacy mode from uefi mode, most systems do. Switching the system back to legacy mode will allow your system to run MBR instead of UEFI so your able to use your windows 7 backup to restore your machine using your tool.
Does the Win 7 backup/recovery option still work on the current builds which have the third (OEM) partition added?
