Public bug reported: This should be an easy problem to replicate and fix. I was installing 18.04lts server on a system with two identical disks in a raid 1 config. When i did the partitioning, i did not set the bootable flag on any of the partitions. (I had in fact reused the partitioning from a 14.04 install but since you cannot go directly from 14.04 to 18.04, i decided to just blow away / and reinstall.)
The issue is that at the point of partitioning, it should have told me that i did not have a bootable partition, rather than letting me get most of the way through and then hanging at the start of the grub install. For all of my other machines, i use the desktop installer with the gui and that does not seem to ever ask me to mark a partition as bootable so having to do it for the server install was a novel situation. ** Affects: grub (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776918 Title: grub installation hang on 0% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub/+bug/1776918/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
