It has happened that I wanted to have Ubuntu OS installed on my Lenovo U165. I have used USB stick to boot from. To create bootable USB stick with Ubuntu I was following instructions from Ubuntu Homepage. I have used USB Creator on old Ubuntu OS installation. Below you can find problems I have stumbled on and how to resolve them.

If you are trying to boot Ubuntu using USB stick and you got following error:

Boot error

Try to check if you have used 64 bit .iso image to create bootbalee USB stick. If yes, download .i386 one and use that to create bootbale USB stick.

If you are trying to boot Ubuntu using USB stick and you got following error:

Unknown keyword in configuration file.

This is caused by incompatible syslinux installed on computer used for USB bootable stick creation. To fix this I have installed new syslinux packages. Debian packages could be downloaded from http://ftp.debian.org/pool/main/s/syslinux/ and installed by following command:

sudo dpkg -i syslinux-common_4.03+dfsg-12_all.deb syslinux_4.03+dfsg-12_i386.deb

If you are trying to boot Ubuntu using USB stick and you got following error:

could not find kernel image: gfxboot

To fix this, you need to mount USB stick read-write and copy file syslinux/txt.cfg to root directory of USB stick as syslinux.cfg.

Example how it could like:

mount -o rw,remount /media/disk
cp -f /media/disk/syslinux/txt.cfg /media/disk/syslinux.cfg
umount /media/disk

If you experience failures during installation regarding SQUASHFS errors in /var/log/syslog do as I did to solve this.
I have installed unetbootin from http://unetbootin.sourceforge.net/ and then on clean USB stick installed Ubuntu 10.10 netinstall image. After successful boot installation over network started and I am happy camper right now.

Last but no least, be sure that your USB key is OK.

HW problems could cause SQUASHFS errors too.
