I have a computer that I have two Hard drives in. ONes a WD 80 GB partitioned into 70 gig, and 10 gig. and the other a WD 10 GB. I thought I installed Red Hat LInux 7.3 on the 10 gig hard drive, but somehow I put it on my 80 gig hard drive that has Windows XP Pro on it.

In hopes that somehow Linux installed on my other non windows partion I tried to boot to Windows on the 80 Gig hard drive. However, I get an error message saying "grub Hard drive error".
I booted up to the Windows Recovery console and it showed that I had a folder on my hard drive which was c:\windows.
I am in the process of installing Windows XP on the 10 gig partion on the 80 gig drive in hopes that I can transfer all my files there.

My question is, is there someway that I can still get my old Windows XP install back? I'm thinking that maybe my master boot record is switched or something like that. I don't know how I managed to do this but somehow I did. Anyhelp would be appreciated.

Ok I have Windows Installed on the other partion now, and I see my other Windwos Install. It even lets me boot to it. So I am now on my old install. HOwever, no I have to Windwos Installs on the computer and I'm afraid that if I delete the one I'm gonna be back to the "grub Hard Disk error". I know theres something I can do to make the computer boot from the old install instead of the new one. Right now as it is I have to select which Windows I want to boot. What do I need to do to not have it ask me which Windows I want to boot to?
