There exist several manuals on how to install Linpus from a recovery DVD.
Basically you just boot the recovery DVD on some PC, select “create rescue usb key” and insert a 2 GiB (or more) usb key.
⚠️ 1 GiB won’t work – the recovery image is slightly larger ⚠️
After the recovery stick has been created, you can plug it into the AAO and start the recovery process. This wipes the complete harddisk so make sure you have a backup of your important data.
