View Full Version : [ubuntu] BIOS can't recognize CD Drive

February 19th, 2012, 04:55 PM

I recently made a clean Ubuntu start in my life and after removing the last ntfs partition and installing Ubuntu 11.10 64bit from a usb stick I inserted a disc into the drive but nothing happens. CD spins but nautilus doesnt show any new drive.

I had ubuntu installed before this installation and cd worked just fine. With the new installation i changed my ntfs partition into ext4 and moved swap from extended to primary, could that be the problem?

When i enter bios, under ide master (where should be CD Drive) says not recognized, so i suppose it has little to do with my OS. Does anyone have any ideas?

Thanks :)

If the BIOS doesn't recognize the CD drive, Ubuntu can't access it. Maybe the cable is loose or the drive is broken?

hmm maybe.. But its funny how it happened just after OS installation, so i figured there might be something wrong with the software.

I will disassemble the laptop if i must, but if you guys can think of something software-wise i can check first, i would be thankful. cheers

If you think that there is a problem with Ubuntu, you could try to boot into a liveCD. If the BIOS recognizes the drive, it should offer you the option to boot from it. I guess it doesn't really matter which kind of liveCD you attempt to boot, any you have available should be fine.

I did as you said, but nothing happens, it just boots into normal ubuntu. In bios boot manager, i cant set to but from cd, just hdd, usb and network. Does that mean it's definitely something wrong with hardware? When i put in a cd, i hear it spinning inside. Maybe that cable got unplugged as you suggested?

Laptop CD drives generally plug in without a "cable." They are often very easy to remove - one or two screws on the bottom of the laptop and perhaps a release latch. I would try popping out the CD drive and putting it back. They DO fail sometimes as well and may not be that expensive to replace. Depends on make/model of laptop.

You may find that with the BIOS set to boot from USB it might remove the option to boot from CD drive and also the other way around. I do not know.

I did find on my system that I could not set a BIOS to boot from USB when it was set to boot from floppy drive. So, it is just something to check.
