Try starting in SafeMode, although if you cut off the repair process it may not work.
You can take out the hard-drive from the laptop, hook it up to another PC with a USB enclosure and get the files from it that way. Will probably need to take ownership of the files to copy them as the other computer won't have the same user rights.
Once all the files, favorites, etc.. are saved, you can re-install Windows clean on the drive. Or a saver thing is to buy a new hard-drive and install Windows on that. That way none of your files are touched.
