The Recovery Partition maybe hidden from view. Being a Toshiba the method to start the system recovery is right after you see the Toshiba BIOS Splash screen hit F11. This should start up the recovery process. If you dont see it you may need to boot using something like GParted or Ultimate Boot CD to see if there is another partition on the drive that you could use to recover. If there is you may have to contact the guy at the shop to see what he did to restore the laptop. If there is no partition you will need to get the Vista Disk. can order it directly from Microsoft
NoName has brought up an interesting point. Not publicly but still he mentioned it to me.
Now there are 2 situations here.
1. The drive is dead
2. The drive has corrupted drivers within Windows
Now for the 2nd otion to be true the only way to tell is to boot from another disk outside of Windows to see if the drive will work. If that doesnt happen than the first option is true and the drive needs to be replaced. But without testing it first there is no way to know for sure if the drive is actually dead.
