hi
i was using a IDE hard disk...that doesnt works anymore....i tried to plug in my old sata harddrive.. and it was detected in bios but couldnt boot windows.. somehow i got it formatted on a friends's computer.. and it was working fine there.. but again when i tried it on my computer.. it was giving bluescreen ( a very quick1) on XP logo..i tired safe mode and safe mode with networking.. both were working fine..some1 suggested to uncheck all boxes in startup and recovery console... since then i cant even boot in safe mode.. and a proper BSOD whiel booting in anymode.. BSOD error says "disable any antivirus prog.. run chkdsk/F for hardrive error and stop 0x00000024.. something like that.. and previous BSOD error was 0x0000007E.. agaain the hard drive was working fine on my friend's computer.

You can't expect Windows loaded on a hard drive from another to boot on another computer without problems
