SSD installed second drive, NOT visible after RESTART, only SHUT DOWN
I have installed a Kingston SSD following the guide on this website,
I have formatted it from the systems HD OS X boot partition as GUID Extended. I would now like to install OS-X El Capitan on it.
The drive is visible when the computer is turned ON from OFF in disk utility/desktop, but if the computer is restarted, the drive is not visible. So its impossible to make it an OS X Boot drive and I'm not sure I want to anyway with it behaving so strangely.
Any bright ideas?
Update (07/06/2016)
I ran the OS-X installer from HD partition, specifying the SSD as install directory. It restarted, it then asked which drive I would like to install to, with only the current HD visible, as i expected.
Then I shut down, turned it on again, and it now picked up with the SSD installation as it should have, as I suppose it was now visible.
So, some progress, but i expect weird behaviour with restarts in the future, So any ideas very appreciated.
Thanks!
UPDATE:
OS X works on new SSD, boots nicely,
However.... Restarting causes it to boot into the old OS-X installation on HD. I need to shut down entirely to boot into SSD OS.
Is this a good question?
