Hi Eli, Here are steps I used to re-install the moblin v2 developer image to an external USB disk, hopefully it works for you. (1) Boot the developer image and select "Boot" option, because we need to do some modifications after the installation. (2) Launch the liveinst by clicking the "Install to Hard Drive" desktop icon, follow the instructions to install to your USB key or disk. (3) In the disk selection menu, make sure you select the right disk for the installation, and the same disk to boot from. (4) After the installation, launch a terminal and mount the new created root fs. For example, in my Eeepc 901, there are 2 built-in SSDs (/dev/sda, /dev/sdb), my USB key with live developer image loaded is /dev/sdc, the target USB disk is /dev/sdd, and I used default partititon layout, the /dev/sdd1 and /dev/sdd3 will be mounted as /boot and / respectively, so I mount the /dev/sdd3 to /mnt for the following modification. (5) Edit the new created fstab (/mnt/etc/fstab in my case), remove any "/dev/sdc" node and change every "/dev/sdd" to "/dev/sdc" because I will boot this USB disk alone without other USB key. (6) Umount the target root fs (umount /mnt) and mount the traget /boot (mount /dev/sdd1 /mnt) for editing the grub.conf (7) Edit the target grub.conf (/mnt/grub/grub.conf in my case), revise the "root=" to the right disk (should be /dev/sdc3) and add "rootdelay=8" to the kernel command line. (8) Reboot your netbook with the new created USB disk.
PS: when you got kernel panic like "VFS: Unable to mount root fs", you could check messages above the panic, if your external USB key were not detected before the panic, you could try to add more seconds delays. FYI.
