I'm trying to install 18.04LTS server over my existing Windows 7 partition. Thinking this should be straight forward I booted into Ubuntu installer and went through and it bombed out. From there I went into W7 recovery using an install USB and used diskutil to clean the disk/partition. Still no joy when installing Windows. I tried to kill the partition/disk with gpartd. No joy. I'm pretty stuck and don't want to go back to W7.
Here is a paste of the logs that showed up in the installer: https://paste.ubuntu.com/p/KdCkkV2DHQ/
Help/guidance/words of wisdom (other than don't go back to Windows!!) are appreciated.
