    Using Windows 10 and Windows 7 (Dual Bios)


    Hi.
    I want to have two OS on my computer, one on my HDD and one on SSD. I already have Windows 7 on HDD and I also have Windows 10 on my SSD but I don't use Win 10 because I somewhere read that for using Windows 10 and Windows 7 in one computer, you must disable fast boot on Win 10 because it may lead to CHKDSK when you want to work with Win 7 and other problems may happen. I want to know is there anything else that I should do to use Windows 10 and Windows 7 in a computer without this CHKDSK or other similar problems? Is just disabling Fast Boot enough?
    Thanks and Sorry for my English.

    Disabling Fast start is useful to avoid awkwardness but is not, of itself, a critical step.

    There are full procedures in
    [if Windows 7 is the currently active OS - which I think is your situation]
    How to dual boot Windows 10 Technical Preview with Windows 7 by JWStuart [I used this procedure when I set up a Win7-Win10 dual boot].
    and [if Windows 10 is the currently active OS],

    The references to the Technical preview merely reflect the date they were written; they are still valid.

    Hi.
    As I said in my question, I have Win 10 installed but I don't use it because I think chkdsk may happen. I read the How to dual boot Windows 10 Technical Preview with Windows 7 by JWStuart But I think it is more about installing the windows and didn't add anything more than Disable fast start to prevent the problem. You said it is not a critical step, so what is the critical step?

    And another question which doesn't relate to the previous. If I upgrade my Windows 10 (old build) with an ISO to newer build, can it cause any problem in Windows 7?

    Thanks.
