There's no need for the Debian entry to be 0000. One normally can change the boot priority order with either efibootmgr or BIOS setup. If the BIOS is broken and an upgrade isn't available, a CMOS reset should provide a workable solution. Pull the plug, take the CMOS battery out, and leave it out as long as it takes for everything to be forgotten. Removing all bootable devices might be required to make forgetfulness stick. If that doesn't work, put a wiped drive in for reset purposes. -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg.
