Hello and thanks guys. It looks like the SDD i was booting from (and had my clone on) just died for no apparent reason and the boot drive i was using was not configured properly. Not too bad I had everythgin but my programs on other drives so, I'm almost back and running.
Big love to Tony and...
I made a new bootloader on a USB and booted from it.
All my hard drives are there except the one with the OS on it which is showing as "Sandisk Milpitas" (uninitialised) this also contained a clone of the working install.
Do i reformat it and install the OS or is there something else...
I have a boot drive, a back up partition and the usb stick all with Clover on them
all my drives show in the bios
but none of them show in Clover.
This is not a new build it's a year old and working well, I was not updating OSX or anything like that and fast boot is not enabled in bios
