    I already have windows 8.1 on my PC. I would like to put windows 10 on my PC on its own partition as a dual boot. The question I have is windows 8.1 is currently on the "C" drive. Once I install windows 10, will that turn windows 10 into "C" or will it keep it installed to whatever drive it is assigned to?

    thx

    When you will boot to windows 10 it always be c:\ (when Windows folder located).

    Once you have installed both Windows 8.1 and 10 in different partitions, if you boot 8.1 it will name its partition as "C" and 10's partition as "D".
    If you boot Windows 10, it will name its partition as "C" and 8.1's partition as "D".
    The letters will be swapped every time you boot a different OS.

    Not necessarily true...Whether I boot 8 or 10 it still shows C as the active partition and the other doesn't exist. It depends how you did the install. If you booted from an ISO it will be like mine and if you installed from under windows it will have a C and a D.

    Usually letters will be swapped if both partitions are Primary, and kept if one of them is on an Extended partition. This is only true for MBR disks, GPT doesn't know Extended partitions anymore.

    Of course, this is only assuming that all Windows 10 RTM versions will be released as separate .iso files in addition to the already scheduled online upgrade. Is anyone certain that this will be the case?
