    Where's my 100MB System Reserved partition?


    I'm running XP Home SP3 and Win7 Pro 32 bit in a dual-boot setup. I use Macrium Reflect to image the entire boot drive.

    Looking at the graphic for Disk Management in both XP and Win7 (shown), I don't see the 100MB System Reserved partition, even though the numbers add up as shown. Shouldn't that 100MB partition be visible? Where would it be located? Between the two main partitions D: and C: ?

    If the drive was already partitoned when you installed Windows 7, it will not create a Reserved partiton.
    It will put the boot data, etc. on the first partition it sees.

    Yes it was already partitioned, via Partition Magic 7.

    Hm. Very interesting. Thank you. :)

    Hi ovenmaster,

    As pbcopter says, it will only create a System Reserved partition on an unpartitioned drive.

    Through past experiences (and headaches) it's no big loss. While it can be handy to have the boot files on a separate drive it can cause problems. It can get filled up and cause errors when trying to create a System Image. I had to extend mine to 300mb to get around the issue. Why Microsoft made it 100mb I'll never understand. It was 200mb in the Windows 7 Beta and they should have kept it at that size.

    As long as you have a System Repair Disc or Install Disc then you won't really need it.

    :)
