Upgrade Booting from Media

[Guest]

By default, to upgrade you have to start the install from a running OS. Is it possible to boot from the DVD and perform the upgrade if for various reasons your current OS won't boot properly?

It's possible providing the failed boot isn't due to a hardware fault, such as a faulty hdd, ram, video etc;.

Jonmor is right, you might want to look into potential hardware issues first before attempting to install an OS again. At the very least, run Memtest86+ to make sure your ram is ok.
