First off, I am a relatively new user of Ubuntu- so pardon me if I am sounding like a bit of an idiot. I've been using Ubuntu for approximately ~8 months or so on my desktop PC, no problems whatsoever. I decided about two weeks ago that it was time to upgrade from 12.04 to 12.10 and do a clean install, and it seemingly went well.
Two nights ago, I decided I needed to install a copy of Windows 7 on the side...but when I hit F12 as I usually did to boot from CD, all that came up was this:
Now, my general guess was that it'd be something to do with hardware...but given that I've never had this problem before, and that the tower is relatively new...it didn't make a whole lot of sense to me. I did a bit of browsing on the Dell forums, to no avail...this error pops up when the hard drive fails as well (sans the CD part), so all I could come up with is stuff for the hard drive. Given that, I figured I'd test if the DVD drive was working other than just opening/closing while using Ubuntu. No luck. It did not want to mount. I'm not sure if this is something related to the installation, since I never used the DVD drive in the two weeks this copy has been installed. I looked on the forums here for any solutions...nothing that I could find. DVD/CD/etc will not mount- no matter the disk. I'm not particularly savvy with all this, so any help at all is appreciated. I'm fine with replacing the DVD drive, but I want to be confident it's that before I go out and replace it.
(By the way...yes the drive was working before I reinstalled two weeks ago...that's how I installed it.)
Thanks so much in advance,
