How can I install the non-CD size 12.04 on a computer that can't boot from USB & can't read DVD-Rs?
Will 12.04 image fit on one 700 MB CD?
Will it fit on a regular 700 MB CD?
Also, I have a macbook that currently has an erased HD (so no OS installed currently) if i boot from a CD can I choose to allocate my whole HD to Ubuntu?
Also the old OS my macbook was running on was 64 bit, should i also use Ubuntu 64 bit as well?
Thanks :)
