Windows 7 Restoring Ranish partion to normal, please help me

[wolfzrat]

Hey Guys So here's the story, I have a Sony Vaio VPCEB23FM, At first when I tried to go to windows i got a black screen that said "Operating System Not Found", so my friend tried to fix it with a windows 7 repair cd, But here is the problem he accidently formatted the Hard Drive which deleted all the files and file the manufacture put in it, he also tried to mess with the ranish partition manager, so he tried to install a fresh windows 7 OSX but the laptop shutoff, now he tried it again and we get a message saying "setup cannot continue due to a corrupted installation file" I cant get to my desktop either, please help me so i can have a working computer again. thank you

Best thing to try first is to see if the Vaio recovery partition is still intact. Switch the pc on and during the startup press F10 - this should boot you into the Sony recovery process which should enable you to recover the pc back to factory condition.
