Ubuntu 14.04 won't boot alongside Mint 16

Question

I have just installed Ubuntu 14.04 Desktop 64-bit alongside a pre-installed Mint 16. I let the installer re-partition my 160GB HDD evenly between the 2 OSes. It never asked me about GRUB, boot loader, etc. Now, it immediately boots into Mint. No GRUB menu or anything. What have I done wrong?! Please help.

Answer 1

Take a look at the Boot Repair documentation, this should get you straightened out.

Answer 2

Mint is basically the same Ubuntu under-cover (16 Petra is tweaked 13.10 Saucy). So the solution would be the same as for Ubuntu.

1. Boot into Mint and edit /etc/default/grub:

   sudo nano /etc/default/grub
   

   Change the line

   GRUB_HIDDEN_TIMEOUT=N
   

   to

   GRUB_HIDDEN_TIMEOUT=0
   

   and save (Ctrl + O)

2. Update GRUB configuration:

   sudo update-grub
   

3. Reboot and see GRUB menu with Ubuntu option.

If you don't see GRUB menu during boot, hold Shift when screen turns purple.
