Reply #6: I tried a variant of this: partitioned a driv into 3 volumes, first a wee big bigger than the [View All]

[struggle4progress]

install disk (according to Get Info), second a wee big bigger than my start-up disk, and third whatever space was left

My TM is on a second external drive

Cloned the install disk to the first volume. Shut down. Rebooted into the install disk volume. Then restored (via TM) my whole system to the second volume. The 49GB or so on my startup drive took about 1.5 hrs to restore on the second volume of the partitioned drive

Comments: (1) There's a nuisance: the install disc folder pops up on every reboot (2) There's an obvious security issue here, since the install disk gives lots of access to the machine
