I have a disk with a Windows 10 installation on a laptop that has suffered an unfortunate accident. I know the hard disk is still good, and now I'd like to move this disk, including the existing Windows installation, to an older laptop I have sitting around. There are things installed here such that re-installing the OS, applications, and rebuilding my profile on the replacement machine would take a lot of work I'd like to avoid.
Unfortunately, the older laptop does not support UEFI boot/GPT disks. I do know the older laptop runs Windows 10 just fine generally (I've had it on this laptop previously).
Is it possible to convert this disk to Legacy/MBR mode in place, or will I need to re-install Windows? If it's possible, how can I do it?
Seems like this would destroy the existing installation. – Joel Coehoorn – 2018-12-28T20:44:26.780
If you have the OS and additional data copied and stored somewhere that isn't the disk you are cleaning, then you should be able to make the conversion from GPT to MBR, move the copied data back over and then run the recovery. It shouldn't destroy the existing installation. – J.Clark – 2018-12-28T20:48:48.253
