If you know how to get into the bios (usually by holding down the Delete key when booting) you can check to see if it is set to boot from CD. Bios navigation is entirely with the keyboard. Bios layouts and tabs are different for different motherboards. If you boot into the bios, you should come to a basic screen. Look at the options on the screen and see if there are boot sequence controls - older motherboards had it there and there were just two options, which device to go to first and then second. If you have that option, set the first boot option to CD and the second to the hard disk. I think most newer motherboards have it on an advanced tab. There should be something like I described above or there may be multiple entries - say 3 lines give 1st, 2nd and 3rd. Again, set the first option to CD and the second to hard disk. If you don't see any of the options I've described, you may just have a bios different from any I've seen. Explore all of the tabs to find these settings. They have to be somewhere. Assuming you've made the changes, read your screen to see how you save your settings. The info is probably at the bottom of the screen crammed among some function key descriptions and navigation instructions. "save and exit" is probably F10; "exit without changes" is probably ESC. Press F10, then reboot with the CD in the drive. If this doesn't work, there are other things to get into, but lots of things can go wrong and you'll be in more trouble if you lose your dad's data. Fess up on what happened and suggest that you dad post a follow-up here if he needs help.

SOURCE: Windows cannot load the device driver for this

Give this a whirl:
CD-Rom stops working. After checking device manager you find an exclamation mark on the drive. It doesn't mean the drive is dead. It could be an upperfilter or lowerfilter registry issue that is keeping you from accessing the cd drive.

This fix worked for my client:

Also, try this fix from microsoft.

CD-ROM access is missing and messages cite error code 31, code 32, code 19, code 39, or code 41.

Try this before replacing the drive and remember that you may have to reinstall some burning software.

You can try to do a system restore using the system recovery.

There are different ways for doing a system recovery on XP computers and on Vista or Windows 7 computer.

Assuming you are using Windows Vista
On boot press the F11 key repeatedly, When you reach the Recovery manager screen select Advance options.

Select the option do restore the computer to an earlier time.

It will show you the restore points

Select the best restore point and try to do a restore

If system restore does not work then you will have to follow the same steps to perform a system recovery by selecting the option to restore the computer to its original factory condition.
