My laptop does not detect any OS after i attempted to install WinXp

[aninda51]

I have a HP pavillion dv-6.

I tried installing Windows XP as a secondary OS, but i got a BSOD every time i tried. To be more specific, I get a BSOD once all the setup files are loaded and it says Setup is starting Windows.

Ever since then, my laptop no longer boots windows 7 up. It goes to the booting screen and the cursor keeps blinking, but thats it.

I think the reason behind this is because xp uses boot.ini, but 7 doesnt, and if the setup files were copied onto the hard-drive, and so was a boot.ini file, it doesnt detect xp or 7.

What should i do? And i was also wondering whether I can use a Hiren's disk to added win7 to the boot manager, something like EasyBCD. If not, does anyone know whether I can detect a 2tb ext. with hirens? I just want to back my data up.

Use Startup Repair and run it 3 times (newer versions of Windows can detect older versions - but older versions can't detect newer versions). Tutorial here: http://www.sevenforums.com/tutorials/681-startup-repair.html

If that doesn't fix it, then use Startup Repair to access the Command Prompt and run these 3 commands (pressing Enter after each one)

bootrec /fixboot
bootrec /fixmbr
bootrec /rebuildbcd
