HOWTO:Boot from USB
From Adélie Linux
These instructions have been tested on x86_64 and pmmx. Your computer must support booting from USB. It is important that "Legacy boot" be enabled in the settings of UEFI computers, or else your computer will silently skip booting from the USB every time. Then you can either change your boot order to put USB at the top, or manually select USB at boot time.
Download the ISO
First you must download the CD image from which to work. You can pick either a "live" or "full" version. Make sure you select the correct architecture.
Burn the image to your USB drive
From the command line:
# dd bs=2M if=/path/to/adelie.iso of=/dev/sdX status=progress oflag=sync
The command must be run as root. Carefully note that
dd is run on
/dev/sdb) and not an individual partition (e.g.
/dev/sdb1). Make sure you select the correct disk device file!
Booting the USB drive
Once the image has been applied to the USB drive, it should be simple to reboot into Adélie. Make sure that the boot priority order allows for booting from USB, and that "Legacy boot" is enabled for newer UEFI-based computers.
