I am not sure whether to post this under XP or 7. I have had XP on an 160GB(C: is 40 GB) drive for some time. Then I bought an 120 GB HDD from a garage sell. (It was pretty old but working). I parted the 120 GB in 2 equals. & installed Windows 7 on first half of the 120 GB drive. Somehow, the bootloader of 7 was installed on 160 GB HDD. so if I kept only 120 GB HDD which had 7 installed on it, it wont boot. And if I kept only 160 GB, It will show a windows 7 loader, with 2 options: default win 7 and 2nd win xp. Still, it went fine for about 6 months and then 120 GB hard disk gave up. it became un repairable and was not in warranty either. Now I dont have the 120 GB hard disk and neither the windows 7 on it. but I have windows xp on 160 GB which is working fine. But every time it boots, It shows the win 7 boot loader and default is windows 7, so if i dont pay attention within 30 seconds, PC tries to boot in 7, and obviously, fails. 1. why was Windows 7 loader installed on 160 GB drive when Win 7 itself was on 120 GB? 2. Is it possible, without formatting windows XP, to remove windows 7 loader and boot from Win xp directly?
