Did you setup BIOS to boot from USB-drive? – Takkat Jun 5 '11 at 14:18
Yes I did, I can even select boot device – sultan Jun 5 '11 at 14:21
I've mounted ISO image from my home directory under the BusyBox shell, so the question is how to start the installation process from this stage? – sultan Jun 5 '11 at 14:33

Try copying the whole text it's more helpful that way:

Remove this:


Add these:

live-media-path=/casper/ ignore_uuid

Full sample:

append boot=casper initrd=/casper/initrd.lz live-media-path=/casper/ quiet splash ignore_uuid -- If you don't want to edit every time you boot from USB, you can edit this file in USB: /syslinux/text.cfg"

Try disabling Floppy in BIOS to find out.

My BIOS doesn't have this option, I don't know to disable this stuff( – sultan Jun 5 '11 at 14:45

Beforte the installation it should tell you that there are still some devices mounted. It will ask you to unmount them. Don't tell it to unmount them as it will also try to unmount your USB drive, wich is the installation medium.
