No boot device means that the computer cannot find a drive that has a operating system files and therefore cannot boot up.
This usually means that the hard drive in the computer is faulty.
You need to get a new hard drive and install Windows on the hard drive, together with the drivers for the computer's installed devices and programs to get a working computer.

To remove the side of the Dell Optiplex 745 cases you need to push the release latch on the back either top or side depending on whether it is a tower or a desktop. The latch just slides back and the side will release and the cover will pop loose. The normal issue with this model is not a bad video card, it is bad capacitors on the motherboard. We repair these boards all the time for a federal prison that is located near our office. Look over this guide we have posted on our site that explains what to look for and what to do about it. http://www.ccl-la.com/blog/index.php/dell-optiplex-745-repair/ The repair is easy to do if you can solder, We have 4 units in right now for repair.

I hope this helps, if so please rate our solution.
