Been working on this issue for three hours with no luck. Will have to post images as the laptop is down.
I could not get to the login screen. Just a blank screen. I was getting an error message about bluetooth. Fixed that. No change. Went into recovery and saw it was not finding a disk. Looked in the /etc/fstab and checked against blkid. The id of one drive was not listed.
This drive was mounted at /media/d/data.
I changed the uid of this disk to my primary Linux filesystem one.
Now I relised that the /media/d/data disk was probably sn external disk that has been accidentaly writted to fstab.
I have two disks for Linux and Windows. The Linux home is encrypted.
Anyone able to make any sense of this. Below are images of the fstab file and blkid output.
