windows 7 not booting

[thiagu]

I am using win 7 X64 premium version , and i tried to install win XP for a dual boot option , but the win XP got crashed and not getting booted , so i tried to boot from Win 7 using WIN 7 REPAIR DISC ( Start up repair) it says no problem is detected and when i restart Win XP gets booted and BSOD occurs

After booting from the repair disk, instead of running Startup repair, open a command prompt and type

bootsect /nt60 all

Hit Enter.

When you restart you should see the win7 menu. Boot into win7, after that use easybcd to create a boot menu entry for XP, as explained here.
