[WLUG] Ubuntu

[Drew]

I use a utility called Super Grub 2. It has an option to boot from the
ISO file that you've downloaded, residing on the hard drive. (It must
be in /boot-images on the partition.) Access time is of reading a hard
drive, along with some delay from uncompressing fron squashfs, but
still much faster than DVD access. It does take some innovation and
finesse to set it up to work smoothly; and not all ISO images will
boot this way. But most will, in my experience.
