Need Help. No operating system found

Recently my computer crashed and I had to turned it off via power button after restarting BSOD came up saying unmountable boot volume.
So I used windows 7 recovery disk and then done the startup repair and restarted the laptop and removed disk.

This time it says no operating system found so I restarted and inserted win7 recovery disk and ran startup repair again it says startup repair cannot repair this automatically. The cause was disk partitioning was corrupt

Then I tried bootrec /fixmbr- successful
Bootrec /fixboot- the volume does not contain a recognised file system.
Also the F8 function doesn't work but the bios does.

Also my local disk is unknown.

I got no important data on laptop

Laptop info: 32bit
Win7
Sony vaio

If you have another computer available, make a Partition Wizard bootable CD. Boot from it, see if any of the repair recovery options might work.

From recovery option I went to load drivers then computer local disk c: and local disk D: are there. So the hard disk is attached but something wrong with the files. I'll try that partition wizard.

So I downloaded the partition wizard is there a way I can format the disk as it was new. So if I insert windows 7 disk I can do a clean install.

Did you read the Partition Wizard tutorial ?

Do you want to WIPE the drive completely & format it to start fresh ?

After you WIPE the HD, choose Format from one of the drop down menus in Partition Wizard.
