I have a Linux Mint 17.1 Partition at /dev/sda1 and another Mint 17.1 Partition at /dev/sda5. How do I set the MBR to boot into /dev/sda1 instead of the GRUB menu? I know how to use GParted to delete the /dev/sda5 partition but not how to set the MBR.
Grub is a piece of software that is installed in the MBR.
Delete sda5 and run grub-update or change grub config manually to boot from sda1, Maybe this howto can help you.
If grub is installed on sda u can change the grub config to boot from sda1. If not try to install grub on sda.
$sudo grub-install /dev/sda $sudo update-grub
If grub-install gives problems, you can install manually from the Grub shell with:
- root (hd0,0)
- setup (hd0)
