I struggled getting minimyth to boot properly from usb flash drive.
the installation script says it succeeded even when syslinux was not installed on the host, so right away it was booting the os on the sata drive instead of from the stick.
(didn't know I needed to install syslinux; didn't see anything about that in the instructions)
I took some notes below.
sudo apt-get install syslinux
# the following is to avoid downloading these files each time the installer is executed
wget http://www.minimyth.org/download/stable ... ar.bz2.md5
wget http://www.minimyth.org/download/stable ... 75.tar.bz2
extract the minimyth.conf file from the .tar.bz2 file & edit for your config
create directory /home/scottc/minimyth/conf/default and place minimyth.conf (and others) in it
pull down 2 scripts from: http://www.minimyth.org/download/stable ... 3/scripts/
make them +x
/dev/sdc is usb flash drive on my system.
delete all partions
make new partition
change partition to fat 32 lba
mark partition bootable
write and exit
sudo bash mm_local_install /home/scottc/minimyth sdc file:/home/scottc/minimyth/
mount /dev/sdc /media/KINGSTON
change ramdisk_size=96000 to 128000
