As far as possible avoid to have a hard disk as slave
So change to master and move your gadgets around so you have one master on each IDE cable. Note the master is supposed to be at the end of the cable and the longer section connected to the motherboard (may work in other configurations, but...)
You are so close to normal boot that this may be sufficient
If not look on /var/log/user.log or /var/log/dmesg for any indications of what's wrong
Note
in Recovery mode you are root - always leave it be rebooting or the exit command
