    Is having two primary partitions ok?


    I'm using Windows 7 Ultimate x64 and I have two primary partitions (C and D).
    Is it ok to have two primary partitions or should I convert D drive into a logical partition? :)

    Hello Nishadrox,

    Yes, that's perfectly fine. :)

    MBR disks supports up to 4 Primary partitions or 3 Primary partitions and 1 Extended partition with up to 128 logical volumes in the extended partition.

    Actually you have three primary partitions there.

    • C: 97.56 GB
    • D: 368.10 GB
    • System Reserved: 100 MB (Hidden, created by the installation procedure itself).

    So, as Shawn said, you have option for ONE more further partition, not more than that. Posting it, lest it becomes useful to you in future.

    I hope to install Windows 8.1 soon. So will I have to extend that 100MB System Reserved partition to about 500MB? I heard that Windows 8 needs a 350MB Reserved Space for its files.

    If you install Windows 8 only, you will do a Clean Install - Windows 8

    In step 8, you will delete C and System reserved, will create a single new partition in the free space, and will let the installer to continue at its own. It will make the other necessary partitions (System Reserved and if needed then the MSR partition).

    I'm going to clean install Windows 8.1 directly. So formatting both C drive and System Reserved space, deleting System Reserved partition and allocating that space to C drive would work?

    Also how much space is needed for 8.1 System partition? Will 80GB be ok?
