I inadvertantly deleted the operating system using fdisk after unsuccessfully attempting to reinstall windows 2000 on a Dell laptop. I reformatted the hard drive, but couldn't get past the security key code. It wouldn't accept the key code I have (??). I have a windows 2000 recovery cd that came with the machine and also another version of windows 2000 on a cd. I can get into the bios. But when I ask it to boot only from the cd, I get a message "No bootable device(s) selected. If I let if default to the hard drive the message is "Missing Operating System". I do not have a floppy drive. It appears to not be recognizing the cd drives (anymore). Any ideas?
