Hello,
I have a Latitude D600 laptop and for some odd reason when I cut it on, it keeps saying no bootable devices--strike F1 to retry boot, F2 for setup utility. I'm not a computer genius by any means at all. I already changed the CD-RW drive to boot first with the Windows Cd in the drive. It works until it gets to the installation part of the CD and it says that it's unable to install. Any advice to get my laptop back up and running would be helpful. Thanks in advance.

We need to know the exact error message.

When it indicates (no bootable devices)
This means that there is something wrong or a damaged hard drive. Have you been messin with the hard drives?

Try installing a fresh copy of windows when you turn on the laptop...
