Kaspersky PURE Installation file crashes my system

NOT ABLE TO CREATE DUMP FILE because of windows OS state

Pls windows gurus and pal, kindly help me cuz i'm in dire need of that:

i thot of changin my Antivirus from MS Essentials to the Kapsersky PURE i downloaded abt 2 moths ago (i can't even remember where i download it from). after uninstaling the current one, i ran the kaspersky pure setup file (approximately the same size as the original one i got from kaspersky website) and wulla, my system has crashed uptill date. windows does not boot but launched auto repair which displays no OS and 'Unknown on Unknown Local Disk' I have tried various suggestions on how to go about it to no avail. i have used Bootrec. exe to fixmbr, fixboot and RebuildBcd to little or no avail, as the Windows now attempts to load then crashes to a BSOD and restarts.

DISKPART displays my Hard Disk's status as Invalid, in my system and even when conected as external drive in another running system.
(WHAT I FEAR MOST), another hard disk also fails to load on my system but loads when replaced in its original system.

Specs:

Windows 7 64-bit Ultimate
HP probook 4530s
4GD/ 320 GB Hard disk

Been using it for about 9 months now.

PLS HELP!

Thanks for the response,

However, i had come across UBCD4WIn and have used TestDisk and some other other repair tweaks to rectify it 2 hrs ago so happy! Thanks once again.

Glad you resolved it on your own. Nice work!
