Help!! Bootcamp disappeared after installation

i have installed windows7 using boot camp 3.1 before installing parallels

right after the installation of parallels desktop 6 completed, bootcamp just disappeared from finder,
and the disk tools show that bootcamp disk is unloaded.

i can't start windows by reboot or by parallels desktop now
and i have some important files on bootcamp disk..

ANYBODY HELP ME????

 

Hello.

Try to mount your bootcamp partition using Disk Utility.app:
1. Boot MacOS
2. Make sure Parallels Desktop 6 is not running
3. Open Disk Utility.app
4. Find bootcamp partition on the right panel
5. Right click -> mount
6. You should see it mounted in Finder now

When start Windows natively what error do you get ?

 

Thanks for your advice.. I have re-installed windows from bootcamp though...

and i have tried to mount bootcamp disk using disk utility, but it didn't work. i got a error message that file system couldn't be found, and i was sure that parallels were not running at the time.
when i tried to boot from windows by pressing alt, i got the message "a disk read error..." and it can't even proceed to the windows logo.

anyway thanks for your kindly reply
