Help! BOOTMGR Missing Vista Main system will not boot!

intalled norton utilities when I intalled norton internet securtiy 2008 and ran disk repair option, and some how my bootmgr got erased or is missing on my main computers vista installation, and I don't know what to do.
I tryed the repair option and the system restore funtion to no avail, I am sure that one of you guys/girls knows what to do. I would have to hate to have to do a full install since i have almost a 500 gig drive full of stuff.

please help, and save me a lot of time.

thanks for any help

You didn't even give us an actual eror emssage to work with

 

Hmm, sorry to see you resort to a format. For the future, partition your drive first, say 50GB for Vista and the rest for your 'stuff'. I've never lost a byte through numerous XP/Vista installs doing things this way. Too bad.
