A. Can you tell me if your laptop can boot from USB key? You should see
in BIOS's boot device section.
B. Also, just because BIOS says so, it doesn't mean it can. I would
appreciate if you could do a short experiment in USB booting.
1. Insert a blank USB key.
and make the whole thing a one partition (ie. /dev/sda1).
3. Make FAT32 filesystem, copy kernel and syslinux.cfg, and make it
mount /dev/sda1 /mnt
cat /boot/vmlinuz > /mnt/vmlinuz
cat > /mnt/syslinux.cfg << EOF
append ro root=/dev/sda1 vga=773
Now, reboot your laptop. You should see 'boot:' prompt, and then
kernel should load. Eventually, it will hang, because nothing is on
/dev/sda1. But, at least, you know it can load kernel from USB key.
