This question already has an answer here:

Recently, I decided to install the loved Linux Mint. I made sure I had space for a partition, and installed it. I am currently on the "trial" part, where it has "Install Linux Mint" on the desktop. I have installed it, and it even has a partition saying "Linux Mint 16 Petra". Yet, when I boot it from HDD/SSD, there is no option to boot to Mint, only my old, broken, ubuntu distro and of course, the dreaded Windows.

I am not sure why this is happening, can anyone do any explaining? I have googled it but haven't found any answers.

Note: After doing fdisk l I got the following message:

`Disk /dev/sda: 320.1 GB, 320072933376 bytes

Note: I am zach, I recently just remembered my old account.

EDIT: I forgot to show you guys what I got for the answer:

mint ~ # grub-install --boot-directory=/mnt/boot /dev/sdb
grub-probe: error: failed to get canonical path of /cow.
Path `/mnt/boot/grub' is not readable by GRUB on boot. Installation is impossible. Aborting.

mint ~ # mount /dev/sdb1 /mnt
mount: /dev/sdb1 already mounted or /mnt busy
mount: according to mtab, /dev/sdb1 is mounted on /cdrom

EDIT2: After performing Graeme's updated answer, No serious errors are there. Now what should I do?

  • hi and welcome to Stack Exchange! bumps are frowned upon here. there's a group of core users that regularly checks the front page; when we do, we'll see your question and take a look. even if bumping pushed your question to the top of the front page (which it doesn't), it doesn't really accomplish anything and just makes us annoyed. – strugee Mar 16 '14 at 23:10

    Looks like @strugee just bumped the question :) – Graeme Mar 16 '14 at 23:14
  • no problem. just to clarify the edit I just made, while the "linux" and "linux-mint" tags are OK in this context, usually you wouldn't need them. we only like to add the "linux" tag if the answer couldn't apply to another UNIX (e.g. FreeBSD). similarly, we only like to apply distro tags if the question only applies to that distro. (here, it's OK because this may be specific to the Mint install process.) – strugee Mar 16 '14 at 23:15
  • You have 'I am currently on the "trial" part, where it has "Install Linux Mint" on the desktop.', then a jump to ' I have installed it'. You did do the "Install Linux Mint" part, right..? – Graeme Mar 16 '14 at 23:16

This is the basic process for re-installing/updating grub on a partitions. You can run this from your Ubuntu system or your live Mint CD. Assumes the system is installed on /dev/sdbx? (not a real partition), you can find your partition by looking at the output of fdisk -l or parted -l. If there is an install log, there should be a record of the system trying something like this and hopefully some useful error messages. If not, you can always try this. It must all be run as root, so do sudo -s first

mount /dev/sdx? /mnt

grub-install --boot-directory=/mnt/boot /dev/sdx  # <--note no partition number

mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
mount --bind /dev /mnt/dev
chroot /mnt update-grub
umount /mnt/proc /mnt/sys /mnt/dev

If it doesn't work, please post the output.
