So I installed a second HDD that I plan on eventually using as my main system disk and did a fresh install of Yosemite on it. The thing, is that I'd like to boot back into the original Macintosh HD so I can start going through what needs to be migrated. I can browse the disk through finder (at least the folders I have permission for), but I can't boot off of it anymore. When I go to
Systems---> Settings--> Startup disk. Only the new drive is listed. Even if I reboot and hold down option, it's the same thing.
Did something happen to to the original Macintosh HD disk after installing Yosemite on a separate drive?
I'm just worried that even if I can't boot into it anymore, I'd still like to be able to pull stuff from my old home folder, but it's saying I don't have permission. What's the workaround for that? I'm using the same login credentials on the new installation that I was on the old one.
