Hi, I have checked the disk as you said. I am not sure if it has made any difference as yet; on first boot it was slow on second it was fast.
On trying to do a new instal on a formatted SSD with no other drives connected, I get the message: ‘Can’t be installed the selected disk is of the GPT partition style’.
I know little about the differences between MBR and GPT only that GPT is preferable.
It did surprise me though, as the drive in question had been a clone of the OS from March this year and I have not knowingly changed partition type. In other words the current working, though problematic drive, has descended from the one I am trying to instal on to. Is this due to the formatting of the drive before the installation attempt?
The pen drive installation I am using is a recent one, the original, which has been overwritten was a few years old.
