Note - I just performed the planned retry and everything installed perfectly.
To summarize: 1) Shut down and disconnected power and data from both primary HDD containing Win7, and the external NTFS drive. 2) Rebooted and left it. This eventually reverted to the Live USB boot disk on the flash drive, which is not what I wanted. Shut down, pulled the Live disk and rebooted. Immediately received a "No Boot Partition Found" error. 3) Rebooted again, this time to the Live USB disk and performed a raw installation. During partitioning, Ubuntu asked if I wanted to install the new OS alongside the already-existing 18.04 instance (I assume this was from the leftover files from the previous failed attempt), erase Ubuntu and overwrite, or format the entire disk and write. 4) I chose to allow Ubuntu Installer to use the entire disk for the root partition. Note - It did not create a swap partition for some reason, but instead used all 250GB for a single root partition. 5) The installer, after formatting and partitioning, just plain worked without any extra complaints. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768621 Title: Installation of Ubuntu 18.04 Desktop installation crashes when unable to write Grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1768621/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
