Hi, My brother recently compressed the Hard drive from our desktop, when he booted the system, he got an error saying "Boot mgr is compressed". I tried booting from the Vista DVD, but I get an error saying "Boot disk failure, please insert system disk and press enter". I tried booting from the DVD in my laptop and it works perfectly. I installed Ubuntu Linux to my desktop so I know the DVD drive is not the problem. I need Vista because this computer is also used by my mother and brother who are not too comfortable with Linux, and I also want to play Civ IV and other Windows games in it. Any ideas on what could be going on? My PC specs: AMD Athlon X2 64 processor. Asus M2N4-SLI Motherboard Samsung SH-S182M DVD burner WD 250GB hard drive NVIDIA Geforce 7600GS Thanks.
