    Windows 10 pro reinstall


    I changed the motherboard in my wife's pc. The old one had legacy bios, the new one has UEFI.
    I booted it with the original SSD with the Windows installation that was running on the legacy bios board.
    All seemed OK at first but the next boot it sat at the UEFI bios splash screen for a few minutes before finally booting into Windows 10 Pro. All programs were unbearably slow. I think because there was no EFI partition.
    I initialized the SSD and did a fresh Windows install and things are working as they should.
    Except, since the SSD is only 120GB, she had the default install location for programs set to D:, a 1TB HDD.
    In Windows settings I tried to set the default program install location to D: but a warning pops that says there are apps already there and they have to be deleted to complete the operation. Everything else pointed to D: without issue.
    Is there a way to recover access the programs stored on D: without reinstalling them and to install new apps to D: rather than C:?
    I have Macrium backups can I do a restore since they were made on the old motherboard with legacy bios. Can I just restore the C: partition and expect it to work as before but with the UEFI bios?

    It should work. I did just that to migrate an install of W10 and it's installed apps from an old Legacy/MBR machine to a new UEFI/GPT machine. I also had to run the Macrium recovery usb's 'Fix Windows boot problems' tool after restoring just the C: partition.

    Thanks for the quick reply and info. I'll have a go at it tomorrow and report back.

    No joy, I'll go through the steps in case I did something wrong.
    Created rescue media on the PC with new motherboard and fresh Windows 10 Pro.
    Ran Macrium Reflect, selected image on drive D: and target as drive C:, Reflect stated it would perform the operation next time Windows PE booted. I restarted and It did the restore. Once restore finished tried to reboot. PC complained that the boot configuration was missing.

    I restarted from the rescue media and selected fix Windows boot problems. The Windows installation on C: was there but after selecting it the only "boot from" options were partitions on the D: drive 1. With no drive 0 options I selected a D: partition. It did it's thing but still no boot. This time the PC gave a Compatibility Support Module (CSM) error saying some of the drives were not fully compatible. Went into bios and tried CSM various options but none worked. Secure boot is set to Windows UEFI but I tried the "other OS" option as well still no boot. I tried a system repair from a Windows boot drive too but it couldn't repair the system.
    Deleted all partitions on drive 0 and fresh installed Windows 10 Pro so back where I started.
    Does my process look right? Any suggestions?

    Did you boot the PC from the Macrium rescue media before running the restore? The message shown suggests not as it states it will restore then next time the PC is booted to the Macrium recovery environment.
    I would boot the PC from the Macrium recovery USB/boot option & restore again & then fix boot problems before closing Macrium & restarting the PC.

    I did boot from the rescue USB and the restore ran automatically. II did reboot before attempting to fix boot problems. I'll try again using your suggestion. Thanks.

    Reporting back.
    The restore worked, PC booted. Drivers and whatnot updated. Everything looked as it did before. Only issue is the computer is slow, throwing lots of errors. The fresh install was super fast in comparison. I don't use that system so perhaps it had issues that were saved to the backup image.
    Seems the best option is for her to begin from a fresh install.

    Yes there may have been errors which were backed up.
    What are the errors?
    Perhaps an in-place repair would fix those.

    Too many errors to mention. I think it stems from programs being installed on the non boot drive. Not sure though.
    It boots with fresh install from power button to sign on screen in 20 seconds. Takes a few minutes to get to the sign in screen after the restore. Then once signed in the errors start popping up.
    I tried a windows repair and it declared it could not fix it.
    She wants her computer back...so I've been told to stop messing with it...lol.
    Most of her files are still on the storage drive. Just had to take full control of folders to get her access to them back.

    If you tried the in-place repair & it didn’t fix the errors then I would recommend a clean install.
