Farik: Sorry to say it, but you're going to have to order the recovery disks from your computer manufacturer. Next time, you need to first try a Factory Image Restore from the Advanced Boot Options Menu > "Repair My Computer". There's nothing you can do at this point if you do not have the recovery disks and you let someone delete the recovery partition off of the C: drive. Worst case (your OEM does not have the recovery media for your laptop anymore), you'll be having to buy a "System Builder" Windows 7 Home Premium for $99.
Akm79: you might very well be experiencing the same problem that I am presently, with a failing main drive. I have performed TWO Factory Image Restores in the last three days and the system keeps crashing and locking up on me, returning PXE "Operating System Not Found" errors when it tries to instead boot to network (can't find the HDD and it disappears from BIOS). It's also making snap-tick/sweep-tick noises even with the OS in idle. And like you, "Startup Repair" refused to work and hung there. If any of that sounds familiar to what's happening to your system you need to keep a close watch on the Event Viewer and look for anything warning you about Event ID 51 and 57, as well as iOStar. These are all related to the main system drive and when they fail, they can also present with freezes, crashes, corruption, BSOD, POST and other nasty errors.
Reformatting (i.e. Factory Image Restore/Clean Install etc.) is only a temporary fix before the drive corrupts the OS installation and the drive completely craps out on you. Sorry to say... especially with prices sky-high as they are for mechanical drives (SSD's are even more ridiculously priced).
Then again, it could also be a system board (Mobo) issue with the SCSI controller/IDE 0 port. The only way to test that is if you installed a new HDD and wait: if it's the HDD the problem will go away. If it is the Mobo, the problem will persist. In the case of the Mobo a cheap but less than ideal fix would be utilizing an external HDD over a USB connection and booting the OS from there instead (providing your BIOS can boot to a USB device, most newer ones can).
