[INSTALL] Windows 7 64x Reinstall Error Code: 0x8007045D

i had to reinstall my windows 7 64x dell inspiron 1750 laptop using my windws 7 home premium disc that came with my laptop when i bought it because it was in a constant starup repair loop. the disc worked find until i got to the part where it said "expanding windows files." it was stuck at 0% after a whilr and then a message popped up that said error code:0x8007045D. during the time when it was expanding windows files i could hear my disc running, but after a while it stops.when i tried running the disc again, the error code message didn't pop up, but the expanding windows files was stuck at 0% forever. when i tried turning on my computer without using the disc, it goes directly from the "finding window files" screen to startup repair. it tells me that it can't fix the problem and i click on a link that tells me that the problem is that my boot configuration is corrupt. i have also ried cleaning my disc and it doesn't look like there's any stratches on it.
