Start up on Mac

[Rob Gendreau]

I installed Breezy on a PowerMac G4; worked great.

Then I had to do some work on my start up hard drive's directory, and  
ended up cloning the system to a another internal drive. Now I can't  
boot into Linux. In essence, my start up drive has changed to another  
internal drive. What's the easiest way to rectify the problem? (I  
noted that now if I use the Mac's start up drive selector, and go  
back to the original start up drive and boot from it, I still can't  
access Linux.)

TIA,
Rob
