W7 Boot problem

I was resizing my partition with paragon partition manager 10, one a partition with my windows 7 on, and one with an old copy of vista that wont boot. It does its thing and then starts to restart, then I get a failure.

It says Windows failed to start. A recent hardware or software change might be the cause.

Status: 0xc0000225
Info: The boot selection failed because a required device is inaccessible.

No idea wtf this means. Please help

O ya, I put the install disc in and clicked repair and its been going for 30 minutes so far.....

And when i went and looked where I could install a new copy, one partition was there, and a windows 7 partition was there but the location didnt have a drive letter, it was (unknown).... IDK why the **** it would be unknown.. Theyre both on the same freaking disc.

edit: startup repair going for an hour so far. (I think it just doesnt know where the partition location is anymore although I think its still there) but i have no idea how to fix

Also when I try to cancel the repair operation as I doubt its doing crap, it says The currentrepair operation cannot be cancelled...... So wtf do I do, hold the shutdown button and hope my HD doesnt fail even more?
