Public bug reported: For a system test I prepared a USB stick with the current focal iso, booted from it and attempted an install to another (identical) USB disk.
During partitioning /dev/sdb (the USB disk) was picked as target for the bootloader installation, a 63GB ext4 partition for / and a 1GB swap partition were created. The install went flawless. After finishing my testing I removed all USB keys and rebooted to find out i am now greeted with a grub input prompt and have no way to boot off the internal NVME disk anymore... Plugging in the target USB stick that was used to install focal to gives me a proper grub menu allowing me to select to boot the NVME installation. So i can only boot with plugged in USB now, without it i end up at a grub input prompt ... ** Affects: ubiquity (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/1872736 Title: install from USB to USB device wipes grub setup on NVME disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1872736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
