    Partitions on C Drive

    I am not sure how or when this occurred but I somehow seem to have ended up with 2 Healthy (recovery partition) both of which are different sizes.

    I assume I don't need both, but how do I determine which is being used?

    Windows RE is only the troubleshooting menu that you get when you hold down shift and click restart from the power icon. It won't contain any system images. The Windows 8.1 factory system image won't do you much good after the upgrade to Windows 10 unless you have software (either factory restore discs or an option in bios) that will access it to restore the factory software load with.

    Windows 10, by default, won't use an actual image to restore itself. Instead it uses files in the WinSxS to rebuild itself. So a clean install will only create 2 or 3 partitions - the OS partition, a small partition that contains the boot files, and a small recovery partition that contains nothing more than the troubleshooting menu. Sometimes the boot files partition and the recovery partition get combined.

    Yeah my problem major one is I forgot to make the Recovery disc originally when I got the PC, guess to in a hurry to upgrade to Windows 10 like my old system was, didn't even find I had DVD's and extra USB drive til I already had 10 installed. Guess i'm SOL if hard drive ever dies and have problems going back to 10, which I hope I don't, but I guess will deal with it then I suppose, not sure if I can do much now

    You can retrieve your Windows 8 product key with Showkey:
    Showkey - Windows 10 Forums

    and you can make a vanilla Windows 8.1 install DVD or flash drive:
    Create installation media for Windows 8.1 - Windows Help

    Also, since you have had Windows 10 on this computer once now, you can reinstall it any time later and skip entering the product key and it will activate using digital entitlement.

    It mentions partition 5, but the partitions aren't numbered - so still not being sure which is the unnecessary one I ran Partition Tool and this was the result..

    The highlighted disc is the system one, disc 2 being a 'clone' backup created by Casper.

    From these results I assume that the one being used is the WINRE partition (650MB) and the other partition Recovery Partition of 858MB is the one I can get rid of.
    The Recovery Partition (18.8GB~) is the OEM partition which has the original 8.1 system backup and I'll get rid of that too.

    Can anyone confirm if I'm right or wrong.
