Booting from a USB Drive

[Dazed_75]

Lisa, the 11th IS the "this Saturday" he mentioned.

Steve, I cannot speak to your several attempts with Arch and other distros.
I can say that if you INSTALL ubuntu to a USB drive (not use a loader with
the .iso), then when you get to the end of the partitioning phase there is
an advanced button on the lower right portion of the dialog box.  If you
click that, you can tell the installer to put GRUB on the USB drive rather
than your hard disk (you may need to have specified manual partitioning for
the USB drive) and after doing that you should be able to use the BIOS boot
menu to select booting from the USB drive.

that I wish it always to be kept alive.
