(Dell Inspiron) No bootable device

Are there any USB devices plugged into your system? if there are, please unplug them and try booting your computer again

Only USB device is my mouse.

Reinstall the OS? Oh man. :-( What good would that possibly do?

okay, go to the command prompt option and type This:
bootrec /rebuilt bcd

rebuilt? or rebuild?

rebuilt

redfang, I got the same error as with previous DOS commands (not recognized as an internal or external command, operable command, or batch file).

Sandeep, I assumed replies to my posts would use the information contained in the post (i.e., the system I am asking for help with). I did, however, comply with your request that I update my specs, which now indicate that I have multiple devices, so there will be no future confusion.

hmmm, Unfortunately, I see no better way to go on with this other than to clean reinstall your system, you may, of course, try a repair install of windows though.
but, before you do that, did i have you do SFC /scannow from the command prompt? and after that, try a system restore from the options menu.
if, however, you decide to reinstall, I'll give you instructions to backup important files, you cannot backup programs already installed, you must reinstall them

as for you system specs, read HERE and update them correctly.

I will try this in the next few days and post back. Thank you for your assistance.
