Resolving Error: Grub not booting into Linux Mint 22 after upgrading from 21.3 on a Dual Boot Windows 10/Linux Mint system
If you have upgraded from Linux Mint 21.3 to 22 on a dual boot system with Windows 10 and are facing issues with Grub not booting into Linux Mint 22, you are not alone. This article will provide a detailed guide on how to resolve this issue and get your system up and running.
Background
Linux Mint is a popular Linux distribution known for its user-friendly interface and rich features. The latest version, Linux Mint 22, was released recently and many users have upgraded from the previous version, 21.3. However, some users have reported issues with Grub not booting into Linux Mint 22 after the upgrade, especially on dual boot systems with Windows 10.
Cause of the Issue
The issue is caused by the Grub bootloader not being updated to the latest version after the upgrade. This results in the bootloader still pointing to the old Linux Mint 21.3 system, instead of the new Linux Mint 22 system.
Resolution
To resolve this issue, you will need to manually update the Grub bootloader to point to the new Linux Mint 22 system. Here are the steps to do so:
- Boot into the Windows 10 system.
- Open the command prompt as an administrator.
- Type the following command to open the disk partition containing the Linux Mint system:
diskpart - Type the following command to list the disk partitions:
list vol - Identify the partition containing the Linux Mint system (usually the partition with the letter
/dev/sdaor/dev/sdbfollowed by a number). - Type the following command to select the partition:
select vol - Type the following command to assign a letter to the partition (e.g.
X):assign letter=X - Type the following command to exit diskpart:
exit - Type the following command to mount the partition:
mount /dev/sdax /mnt - Type the following command to update the Grub bootloader:
sudo grub-install --root-directory=/mnt /dev/sdX - Type the following command to reboot the system:
sudo reboot
After following these steps, the Grub bootloader should now point to the new Linux Mint 22 system and you should be able to boot into it without any issues.
