I installed Ubuntu, but when I boot I go straight to Grub rescue command prompt (GNU GRUB version 2.00-19ubuntu2.1). I can get a Grub boot interface by typing:
set root=(hd0,5) set prefix=(hd0,5)/boot/grub insmod normal normal
And I can then boot into either Windows 8 or Ubuntu. But I really don't want to type that every time I reboot.
For reference: I have a new 2013 Asus Q501L. It had Window 8.0 preinstalled. I shrunk the Windows partition, leaving the other Windows partitions alone, including sda1 and recovery. I installed Ubuntu on the space I created from the shrunken Windows partition.
I have tried the following to fix this:
Boot-recovery (both legacy mode and EFI mode as described here (That is, I get the WinEFI detected message in Boot Repair, but I've tried it both with and without activating the Windows efi inside Boot-Repair). Boot Repair says, when finished with non-efi approach: Please do not forget to make your BIOS boot on sda1/EFI/ubuntustudio/shimx64.efi file!. But in my BIOS, the only Ubuntu boot option is "ubuntu (PO: Toshiba MQ...75).
The instructions here for reassociating grub with the boot partition
- The instructions (Stuck on GRUB Command Line) (note, no rep so limited to 2 links) for using the CHROOT method
- The instructions here to change the Grub record timeout.
In the Grub command line
I really am at a loss. Here is the output from
sudo fdisk -l:

Here is the result from df -Th:

Please help! I don't want to customize my Ubuntu install until this is resolved, because I'm not sure I won't have to wipe everything.
UPDATE: I installed rEFInd. It worked, but only if I boot from the default/generic variants. I still can't boot from the specific Ubuntu versions that Ubuntu tries to use, as those go straight to the Grub command line.
