If I let XP boot, (it is the default) it comes up fine. If I choose to start Vista I get a blue screen that only shows for a second or two. It basically says that the boot sector is bad and I should do a repair of Vista with my original CD. To get my system back, I reload Vista from a Ghost that I did just before the upgrade to SP1. I've tried to upgrade Vista to SP1 twice, with the same result.And how do you mean "corrupted"?
What error? When does it happen (i.e. do you get into XP at least?)? How do you fix it?
I have EasyBCD loaded on the Vista partition, with XP as the default OS. In the "View Settings tab are the following items:What are the settings of your XP entry as shown in EasyBCD?
