How do I install from external DVD
I have Windows XP on a 3Gb partition, and Ubuntu 7.04 on the remains of 10Gb.
I would like to install Ubuntu 8.10 (external DVD) over the 7.04.
My DELL Inspiron 7500 doesn't seem to be able to boot from the DVD, although the BIOS says it will. I don't know, maybe it has to be an internal DVD??? Anyway, I am trying as many different possibilities I can find.
It seems that if I load 7.04 in recovery mode, I get to a terminal line - is there code I can input to boot the external DVD to install?
Ubuntu 14.04; AcerAspire AX1301-U1302
