How do I Install Ubuntu OVER opensuse? ?

Question

Everytime I put the Ubuntu disk in, it won't autorun or boot. At first, I had Ubuntu just installed on my system...so I installed Opensuse just to try it out hoping I could load Ubuntu back in since I just had tried it. Well, Opensuse has been a hassle and everytime I try to put in the Ubuntu disk, it wont auto run, or boot..Its practically useless! Please Help! My PC is in Crisis mode

Answer 1

also, burn the disk at a slower speed.....sometimes the cd isn't certified to that speed or the cd drive can't read it will give you boot trouble.

Answer 2

put the disk in and reboot your PC, when you see the first screen press F12 to get to the boot menu and then choose boot from CD. Make sure you back up all your data that you want to keep first
