Hi,
This is what it is for
Startup Repair
and this is what you are making to do the job
Create a Recovery Disc
I made one recently for a friend , it is all easy to do , including setting up bittorrent - I did it just for that download.The disc you make will be very useful for the future.
Alternatively, if you know someone with a Vista dvd 32 bit, you can borrow that for the startup repair. You could even make your own dvd from the borrowed one, using isorecorder ( see the tutorial ). Remember when burning bootable iso to cd or dvd, do not format the recordable disc - if Autoplay pops up, just close it.
Hope it helps
