Windows Vista Ultrmate

I keep getting the screen at boot time, where it says

Normal Boot
Safe Boot

It said that Windows could not logon, and to use my disk then choose
R for repair. Any ideas why this keeps happening. Thanks

I had something like that and I hope it is not the same
but I would give you hard drive a defragment now and see if you have a
black hole starting
sorry I hope my information is wrong
