I would say I am 75% sure the DVD drive is ok, but certainly worth checking out a I have a spare lying around.
Anywho that aside I am having serious problems with kubuntu.
Never really used this version before as I have always used Ubuntu (gnome)
Well to get back on my train of thought...
I booted up into Kubuntu from the live disc and did an installation on my spare 40Gb HDD, overwriting my Ubuntu install for that same machine.
Started to install Linux MCE wheer it then said I needed to update to the restricted drivers for my nvidia card (Geforce 2). After doing this I had to reboot and that was when things went bad...
on reboot all I got after the kubuntu splash was a cursor flashing in the top left corner of the screen.
I tried a reinstall, but that failed mid-way.
To eliminate the HDD I switched to a newer drive and the exact same thing happened.
Not 100% sure of the spec, as I aint home just now, but I think its a pentium 4 3Ghz 1Gb ram and a geforce 2 card.
Puzzled as to why Kubuntu would have issues installing on a system I had Ubuntu 704 installed on with no probs.
