You may want to ask at the English Amiga Board (google it) but...
Only the amiga 1000 requires a startup disk (kickstart) so you're fine there. The hand is asking for a bootable disk, either Workbench OS or a program disk - games or otherwise. What kind of disk are you trying to boot? If its just showing the white/gray screen with no loading, it could be a number of things...
Bad disk
Bad disk drive
Bad ram
Do you know if it has expanded ram? That happened on mine when the ram expansion came loose (its underneath the amiga, beneath the door) just take it out and plug it back in nice and snug
I checked, it doesn't have expanded ram. I tried booting an Amiga Extras/Basic disk and also a game. Some of the hardware must just be shot then huh?
