[SOLVED] Two bootable drives - need to make one nonbootable
I have two drives - a 160Gb with Zentyal and a 1Tb with Ubuntu and XP. The 1Tb has some data on it that I want to keep. Other than the data I would be happy wiping everything else out and using the drive as a data drive for the Zentyal server.
Everything I plug both drives in the machine gets confused and boots from the 1Tb Ubuntu server and reports that there are problems with the 160Gb drive. How would I make that 1T drive non-bootable so I can boot with my 160Gb drive and finish cleaning the big drive and prepping it for being a data drive for the server?
