Hi I recently got a Dell Latitude CSx from a friend and it has no floppy or cd drive. You're guide is great and should most definately work, but I have run into a "Missing Operating System" error when I put the hard drive back into the laptop. When I did a test run on the desktop that I used, it boots up fine and MS-DOS loads and I can access the c drive without problems. When I stick it back in the laptop, I always get the "Missing Operating System" error. Any ideas how to get around this little problem? Thanks in advance.
