If you want to reinstall windows and lose everything you can fix:
"An error occurred while setup was updating partition information on:238473 MB Disk 0 at Id 0 on bus 0 on atapi (MBR) Setup cannot continue. To quit setup, press F3."
by going into the BIOS and disabling MBR/Bootsector Virus Protection
Secondly, if you DO want (if possible) to keep your files and can get to a command prompt try typing sfc /scannow
