Hi everyone, I'm new to this forum and I'm looking for help as to why my PC is displaying this message. After changing my BCLK from 180 to 185, I was met with the message "Missing Operating Sys_" on a black screen. I've tried using the Windows 7 CD my computer came with, but it can't reinstall itself due to a partition already being installed on the computer because "Unable to create a new system partition or locate an existing system partition". Basically, my computer is stuck at the black screen at this point. Any help is greatly appreciated.

hmm cant remember the exact commands but...

insert your win7 dvd then go to recovery console...
in their type (i think)::

* bcdedit /export C:\\BCD_Backup
* c:
* cd boot
* attrib bcd -s -h -r
* ren c:\\boot\\bcd bcd.old
* bootrec /RebuildBcd

in that order obviously, that should fix all booting problems...
but the problem may be with a fualty hard drive?
