Dual Boot Installation with Windows 7 and Vista

Hello,

I had a dual boot system of Vista and Win7 but choose now to reinstall the corrupt Windows Vista portion. Is there a way to do this without also wiping the Window7?

Thanks for the reply. That was what I was thinking, but the dvd woudn't boot even though I could view the contents from the Win7. I tried another cd for Win XP and that wouldn't boot either. What could be causing the disks not to boot? I have two dvd readers (a SATA and an IDE) both see the disks but neither boots. I just get a blinking line for a second or two and it goes into the dual boot menu. I tried setting the BIOS to one dvd drive then the other but neither boots. Ideas?

Yeah, I was just getting the two drives mixed up. I reinstalled Vista but still had to reinstall Win7 as well. No big deal, both installations were new. Thanks.

After several unsuccessful attempts to upgrade Vista to 7 I found this forum and used the dual boot procedure. Works great. I don't need the upgrade if I still have access to the files on the other system. The procedure worked flawlessly and I now have a fully functional Win7 system to configure as I have time. If I still need to do things in Vista pending conversion, it is not an issue.
You folks on this forum are great and I truly appreciate the help.
Now, if I could just get Microsoft to tell me why the multiple upgrade attempts failed and reverted back to Vista I would be very happy. I just don't understand how the upgrade can go through the entire process and then at the last tell me it was unsuccessful and revert back.

Anyway. I am good to go and thanks again.
