You run that inside maemo terminal: any time you make any changes to the files in /etc/bootmenu.d/ you need to run that. If it saying command not found, have you installed u-boot-tools and u-boot itself (not from the repositories)? https://atrey.karlin.mff.cuni.cz/~pa...c3-1_armel.deb Edit: You really need to read the first post of this thread VERY carefully. From the other thread it seems you have installed u-boot from the repositories, which is broken. You need to completely remove u-boot, and install the versions from here. this, this, and this.
