Thank you Mr. Susi, but I have tried to install Ubuntu with the "use entire disk" option in both EFI and BIOS modes.
After installing in EFI mode, grub2 produces a visible menu, but the machine hangs when any menu entry is selected. In BIOS mode, after installation the machine boots to either grub rescue or just the grub> prompt. The only solution I have found is to use the boot-rescue program to repair the grub installation in legacy mode, which seems to install an older kernel. It is a peculiar problem, because I can't find anyone else suffering from it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1688986 Title: Can no longer use Grub2 to boot.
