Hi All, I need some help here.I have DELL Dimension 3000, with XP HOME on it, has been working fine.I wanted to load XP PRO on it. Since I don't have a floppy or bootable CD, I removed the HARD DRIVE from 3000 and installed it on my VERY OLD DELL PC (DELL XPS ) , REFORMATTED it and loaded the XP Pro.(NTFS)It worked fine on that OLD PC.Now, when i removed the Hard Drive and placed it on the Dimension 3000, it didn't work.It gave me a blue screen saying, an error occured..check hard drive etc..I even RESET the BIOS to defaults.The same HARD DRIVE works on one machine but not on Dimension 3000.I reformatted the HARD drive again and installed the XP Pro using my OLD PC.Still didn't work on 3000.Why the HARD DRIVE with XP PRO works on one macHine but not on the other? Both are DELL.BUT when I load XP HOME on that hard drive from the 3000 it works fine.Is it XP HOME and PRO conflict or NTFS issue?I converteed it to NTFS while formatting.Your reply will help me a lot
