on a separate issue, you said your actual dvd drive does not work in the laptop, if it doesn't show up in bios its definitely a hardware issue or firmware, i have had issues in the past of a dvd drive not showing up in windows and usually its due to a recent software installation that gives you a virtual drive of some discription, like norton 360 live update, majority of usb internet dongles ect. there is a simple fix through regedit.exe to fix the registry errors, depending on the laptop and if it is still in the warranty period they should replace the drive, if not there should be firmware updates online, i know this doesn't actually help you at the current time due to not being able to load windows but for future reference.

the upper and lower filters that are in the registry that can cause your dvd/cd drive to magically disappear are here

Open regedit.exe (windows key + R) type regedit and push enter/ok

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

you really only need to look for the first 4D entry.

on the right you may see upper filters and lower filters, delete both and restart your computer.

upon restarting you will see your dvd drive has magically come back to your my computer.

This is a common issue and cause for dvd drives to go limbo

It's not clear if there is a cd/dvd drive and it's broken, or if this lap top never had an internal cd/dvd drive.

i was going off the "cd driver" comment from the first page, I am just assuming it does have a physical drive there and the driver/firmware/hardware is failing. unless it was a typo and there is no cd drive. so yes i agree it is unclear although those troubleshooting steps would help figure out exactly what is wrong with the drive if it is physically there.
