You need some kind of bootable media.

On a working pc download and burn to cd PW free boot cd. Partition Wizard Bootable CD allows user to manage partition directly with partition manager bootable CD.

Boot it up on the sick machine.

If you have 100mb partition, rt click it set as Active, ok , apply.

If you don't have 100mb partition - then try setting the main windows partiton Active instead - if that doesn't do it, set the manufacturers recovery partition Active.

Do you have a Windows 7 installation cd? If you do, boot your system off of it and when it comes up to the screen saying Windows 7, click on next. Then on the screen, click on repair your computer in the bottom right. It may find errors before you have to select an OS to repair, but if it doesn't, select Windows 7 and press next. Then, click on Startup Repair and let it run. It may take a while depending on what it has to repair.

Hiyya woot and welcome

Didn't just so happen to make either a rescue disk or system image by any chance?

I don't know about evryone else but would a safe boot work? - F8 on power up.

Personally I would - only because I can hook the HDD up as an external to another machine and try and get that data off that way - possible?

Um what about that USB install method download the ISO - boot from it and when the screen comes up do a repair?

If you do a factory default though your can kiss the data bye bye. - maybe even Recuva may work even then? as I have used that before Recuva - Undelete, Unerase, File and Disk Recovery - Free Download

Since you don't have an installation cd, just download one of these legal install cds to do the repair: Official Windows 7 SP1 ISO from Digital River My Digital Life
You can also use the disc to reinstall Windows with a clean install which you may have to do depending on if doing what i and SIW2 said works or not.

Yeah I meant that only I did the same thing using USB Windows 7 Installation Key Drive - Create and it worked a treat.

Sorry you other fellows didn't mean to confuse the issue

sir i did what you said and in the main screen of PW says..

DISK1 Capacity used
*recovery 14 GB 13.92
* 450GB 0

probably means that i erased all the data from my main hard disk (the one in my pc)

yes god now i could die

Now one last suggestion and I really don't mean to interfere windude and SIW but is there any chance of getting the drive onto another machine as an external and try the Recuva from it?
