I'm a recent kubuntu user (one month). To make a long story short, I started with kubuntu 6.04, and progressively upgrade it until the latest version: kubuntu 8.04.
Everything was running perfectly until I tried, like many other people in here, to fix this cdrom problem (DVD not detected during installation). Before I did anything weird, I remember that the partitions after installation were: one for xp, one for kubuntu and two small that I never understood why they appear after the first kunbuntu installation.
Anyway, then I made a stupid and irresponsible mistake: I set one of this small partition as being the DVD... I just messed it up...
Now I can get to the panel which allow me to select between xp and Kunbuntu. But kunbuntu crashed when it try to access to a file in ../sbin (permission denied). I think that I link the DVD to the partition sta4... I don't really understand why but I cannot boot from the live cd (the dvd doesn't run, even in xp).
I obtained can see the wrong line in fstab using cat /etc/fstab, but I don't know how to modify it from grub.
I hope you can help me, I'm getting crazy with this problem... I cannot run any more Kunbuntu...
P.S: remember I'm a newbie to linux
