Had the same problem and I used this and it worked, doesn't matter that it's not a rapidshare virus as it says in the link, it should work. If you don't want to get that guy's archive, just download testdisk, cause that's the program he uses(he probably has more progs on that bootable disk of his).
Next time you get errors like that MBR one don't rush and reinstall the Windows, with a google search you would have found out that all you needed to do was copy two files from the windows boot disk to the first partition to get things going again.
Good luck(replace the (dot) by .)
