Don't know if I have done the right thing or not, but I have deleted partitions 6-3, and tried to start from that point. Have tried writing +4G after the first sector, but eventually I get a line saying out of range. Get a different error message when typing it after the next line for last sector. Also now seem to have lost partition 6 as an automatic option. Below is one of a few attempts.
