It could be bum.
I have a Samsung NP300E5C-A01US Windows 7 SP1 laptop that's stuck in a System Repair loop, but when I try to boot from my system recovery disc, it just boots right to the system repair options with the Black screen saying, "Windows is loading files." The strange thing is, I burned a copy of Hiren's BootCD to a CD-R and it seems to boot that up just fine. I disabled Fastboot and made the DVD drive 1st boot priority in the BIOS, by the way.
How can I get my laptop to recognize my Windows repair disc?
