Is there a way to repair a system drive when it's secondary?

    Ok, messy title, but I'll try to explain:

    Long story short my windows 10 drive broke horribly, couldn't boot, and I eventually got it fresh installed on a different drive.

    Which can see the original system drive.

    It just can't boot with it any more - all the data is fine, and I tried EVERYTHING to save that install but it wasn't playing ball.

    But... now I'm wanting to see if that drive/install can be fixed 'from a distance' - is there any software that can look at another disk and salvage a windows install from it?

    Thanks!

    If its the boot loader side, you could use something like macrium to clone the hidden boot partitions over. But anything else it will be not as simple.

    If you can see all your data, back up everything important, format the drive then do a fresh install?

    Do believe it's just a broken boot sequence yes. I have Macrium installed, wonderful app - but how do I do what you're suggesting?

    Yes, but was hoping not to have to. Have done that already, and all the data is safe there, but the original install had everything as I wanted it, so wanted to see if that was restorable.

    MAcrium have some great docs, the method I would do is as follows.

    First backup the original partitions, as you could well make things worse.
    Second backup the new partitions from the new install.
    Third restore the second backup over the partitions on the first install.

    You can do all this inside Macrium PE, so make a USB Macrium PE before you start.

    I might be missing something, but all you're doing is asking me to copy the image of the broken partition/boot drive to another drive. It'll just copy the breakage over too!

    No?

    DISM++ never failed me in such situations.
    https://www.chuyu.me/en/index.html.

    Via a bootable USB (ie, macrium or any win10 PE based flash drive), copy it to any of your drives.
    Unpack it, click on Dism++x64.exe and it will show you any installed windows OS's. Click on the OS, then select recovery tab > bootmgr repair and it will be running on next bootup.

    @alanm Yes I agree with you, and we still need to remember the Mouri Naruto too I think for its brilliant explanations :)
