In need of replacing the very out dated XP sp2 on computer
downloaded the latest ISO file from down load centre -which was in a compressed file
i originally burnt onto a cd disc on basis I could then boot from CD and then have a seamless change over to Ubuntu
I don't appear to be able to boot from the disc as first option, I checked the boot sequence this was all confirmed despite hitting F12 to change boot location no luck period.
Should this ISO file be unzipped or decompressed and then boot from cd disc or am I missing something
alternative is I try and deinstall XP from computer altogether and hopefully then I can boot from disc ?
