Good idea but changed nothing. Only lost the use of some of my USB ports for key boards, mouse etc. I put the choice back to Legacy Enabled.
Since all of this, I've removed all but the single 3tb hard drive I want Zorin to reside on. Removed all manual partitions, booted the computer up via the Zorin USB installation stick and then let Zorin install itself without any manual partion creations. Sadly, computer boots fine on the USB stick but still will not start from the HD.
I may start a new thread as I've given up trying to boot between HD's and OS's. I now have only the one HD with Zorin installed. Seems to be clean and the computer simply asks to reboot once the install from the USB stick has completed its job. But as mentioned from the start, the system refuses to boot from the HD.
Very strange that the computer starts on the USB but not on the HD.
Thoughts? Many thanks everyone. PC
