Three possible problems:

a) the disks got scrambled by a magnetic field or are just old

b) your disk drive speed is out of whack and needs to be adjusted. You
need to find a copy of Copy ][ Plus (versions 3.0 and higher?) which
includes a disk speed alignment program. You need to open up the disk ][
and use a small screwdriver to tweak the pot controlling the drive speed
per the on-screen display of Copy ][ Plus.

c) the disks you are trying to boot require an amount of memory that your
][+ does not have. Older ][+ systems only came with 16K, upgradable to
48K and 64K with a "language card". The disks you are trying to boot may
require 48K, and you may only have 16K.

Pressing RESET alone on the ][+ will suffice to break into the basic prompt.
