    Hi,

    I have an SSD with a single partition with WinXp on it.
    I have an HDD with three partitions on it: Storage (NTSF-300gb), Zorin (ext4-80gb), and Mint (ext4-80gb).

    When booting up the computer it brings me to a screen (possibly Zorin related, it uses its color scheme) that lists several options:

    -Zorin
    -Zorin Advanced Settings
    -Memory Test
    -Memory Test (something)
    -Windows XP Professional


    Would this be the GRUB screen?
    How do I get Mint to be listed/boot?

    Thank you.

    Yes, that is the GRUB bootloader you're seeing.

    Within a zorin terminal, installing os-prober and running update-grub may do it for you.
    Code:
    $ sudo apt install os-prober
    $ sudo update-grub
    
    Should be low risk but could potentially muck boot depending on how you've set up your system. os-prober is intended to automatically detect other operating systems and is called as part of the grub update process if it is installed, and update-grub is called whenever there's a kernel update anyway, so this process isn't something you wouldn't encounter regularly during standard updates, albeit automatically rather than manually, and shouldn't have any impact that would not also result from such an update.

    If you have anything critical you don't want to lose, you should have access to a live disc to move stuff as needed or fix boot if it breaks or much better, a backup. This should be standard operating procedure whenever you want to make any sort of system level change, of course.

    Thank you.

    Terminal told me os-prober is already at newest version.

    Here is the result from update-grub:

    Generating grub configuration file ...

    I'll reboot and see what happens.
    UPDATE: No change. :(

    Can I see the output of
    Code:
     $ sudo blkid 
    I'd like to see how your partitions are mounted. I'm not an expert but I wonder if you might have a separate /boot partition with that was overwritten when you installed Zorin. If not, I don't have any other ideas and will leave you in the hands of the rest of the community.

    Here. I censored the long bunch of numbers, I don't know if that knowledge is sensitive or not.

    /dev/sda1: LABEL="STORAGE" UUID="-------------------" TYPE="ntfs"
    /dev/sda2: UUID="-------------------" TYPE="ext4"
    /dev/sda3: LABEL="mint" UUID="-------------------" TYPE="ext4"
    /dev/sdb1: LABEL="XP" UUID="-------------------" TYPE="ntfs"
    /dev/zram0: UUID="-------------------" TYPE="swap"
    /dev/zram1: UUID="-------------------" TYPE="swap"


    I don't think it will tell you much. The problems my computer has are inexplicable. Thanks a lot for responding though.

    UPDATE:

    I have a live-boot Zorin CD and a live-boot Mint USB. The computer will boot from the CD, but not from the USB for some reason (yes, I have it listed in order in the boot setup (F2 on start)), but if the Zorin CD and the Mint USB are both inserted the computer will live-boot Zorin but I'll end up in Mint. Weird.

    Anyway, in a last-ditch effort I made a live-boot CD with Mint on it. The computer booted Mint from the CD and I installed Mint from it without issue. Ta-da! Now when starting the computer it brings me to a black-colored GRUB and ALL the OS's and their options are listed. I have not tried to select XP or Zorin in the GRUB but I have no reason to believe they won't work. I'm posting from Mint right now.

    Mint is taking a long time to run its update (I told it to update). I am no updating FF because I'm afraid I will loose Flash like I did when I updated FF in Zorin. I'm looking forward to seeing if Mint will run more games than I could in Zorin. I'll cross my fingers.

    Thanks.
