Windows 7: Partitioning - created a partition and can't boot!

Partitioning - created a partition and can't boot!

Hi folks, I put a clean install of Win 7 onto my laptop and all was well. I went into disk management and shrunk my C: partition a bit to create a new partition.

Having done that, I now cannot boot up. It would seem that something I've done has caused the system reserved partition to become my C: drive and what was C: is now D:! W7 attempts a repair when I boot up, but this fails due to a corrupt registry.

I've put the disk back in to see what that offers and it's here that I noticed that Windows is now on the D: drive. Opening a command prompt confirms how the drive letters have been reassigned.

I'm not 100% sure but assume that it's trying to boot from the system reserved partition and not liking it? I only just installed yesterday so don't mind doing a reinstall if that's the easiest fix, but just wonder if anyone knows what I can do to ensure this doesn't happen again? I presume my partitioning shenanigans are to blame somehow?!

Hi Richard,

There wouldn't normally be a problem shrinking the boot partition with Disk Management.

Are you sure you didn't do anything else?

At this stage - reinstall is probably easiest - you've probably done it by now.

Hi, thanks for the reply. Pretty sure I didn't do anything else other than install Office 2007 and Steam. As you suspect I've reinstalled now and so far its working fine - fingers crossed it stays that way!
