A year or so ago I partitioned my stock 2011 MacBook Air with a 30Gb (I think) partition for Ubuntu. For a while I dual booted, all was good until eventually I purchased a dedicated Ubuntu machine and decided to return that space to my Mac.
I killed the Ubuntu partition with Gparted, but couldn't find a way to extend the Mac partition.
Using Disk Utility I get the following problem
I've tried the suggested answers here: https://apple.stackexchange.com/questions/139157/restore-macintosh-hd-to-its-original-partition-configuration
But if I run
diskutil cs list I get told I have no Core Storage volumes.
Any ideas folks?
Edit: I really don't care if I have to do a full machine restore. However, I have no time machine backup.
