I just installed a new 60gig hd with windows xp. I have it hooked up with my ten gig. But when i take out the 10gig so then i just boot from the 60gig. It says NTLDR is missing. so i cant boot. Anyhelp would be good.
Actually, with Windows XP, he doesn't even have to do that
Do what Sprung said and swap your 60gig. Make it the master and the 10gb the slave.
Then, put in your Windows XP CD and boot to the CD. When the screen asks you to install, choose Install. The CD will then check the 60gb hard drive. It will then pop up with a message that says, "A Previous Windows XP Installation Has Been Detected. Do You Wish To Repair It?" Press "R" to repair. It will then remove Windows, and reinstall it. This way you don't have to wipe it out and put all your files back.
