On Dual boot (Grub default) Win10- Ubuntu18.4 system I want to install Peppermint 9

  • 772

On a Dual boot (Grub default) Win10- Ubuntu18.4 system on a Dell Inspiron 15 3567

I want to install Peppermint9 as a 3rd system- will it figure out how to add itself to the Ubuntu GRUB, overwrite GRUB with it's own and all 3 systems, destroy it so nothing boots, or how do I do that myself?

grub2 dual-boot

  1. You should just add the third partition like you did with the second os. This guide should apply. Just replace Mint with Peppermint!

    Just install normally. You can boot from your USB and follow the steps of the installer. You can either create a partition manually before installing or use the tools provided by the Mint installer to partition during the installation process.

    The only thing you really have to worry about is when the installer asks you whether to install a boot loader (GRUB). Then, you have 2 choices. Since you already have a GRUB installed by Ubuntu, you can either choose to not install a new one from mint and use Ubuntu's or you can install Mint's and overwrite Ubuntu's.

    Use the existing GRUB.

    When the installer asks you whether to install a boot loader, say no. Once the installation has finished, reboot and load Ubuntu (Mint will not appear in the list of available OSs). From Ubuntu, refresh GRUB so it will detect your new Mint installation:

    sudo update-grub

    Use Mint's GRUB.

    When the installer asks you whether to install a boot loader, say yes. Make sure you install it in the same location where your Ubuntu's GRUB was installed. This will probably be the master boot record (MBR) of your primary hard drive. Reboot and you should now have Mint's GRUB installed and will be able to choose Mint, Ubuntu or Windows.

  2. Ubuntu found the aborted Pep installation (bad disk) on an update and added it, but Peppermint overwrote it with it's own more primitive bootloader, which found all OS's.
