Thanks for the reply
I did not burn the CDs I bought them with a linux magazine and worked quite fine before.
You are right thou about the CD drive, it is quite old one the style that you have to put the CD in a box then insert it in the drive after yet its speed is kinda decent 12X.
The machine is not mine so i do not know if there is issues with the CD drive but seems there is not.
Should i replace it with another CD drive and try to install from there?
Also if the errors related to the log in manager, why I do not find the applications? or find some with Gnome less with other GUIs and none with KDE?
Thanks
