Sorry,
I’m half asleep here as i see you did mention this in an earlier post now that i read from the top. So when you installed Mint did it take over control for grub to boot because you installed it after i would think it has. I think what you are going to have to do is boot up on the live Endeavour ISO and Arch-chroot into the system and try to fix the boot by reinstalling grub. It’s not hard you only need to follow the instructions.
Edit: Also you mentioned about audio issues even on Mint. Your hardware has sof-audio-pci
This requires sof-firmware to be installed in Endeavour after when you get it working. On Mint you may also have to install it as I’m not sure whether they do or not but on arch it is not installed,
It’s pretty straight forward but i think you can get lost with the instructions. Basically you just boot on the live ISO.
sudo su
Then you have need to know what your partitions are. Once you determine that. You need to mount /root.
mount /dev/nvme0n1p2 /mnt
Then you have to mount the efi partition.
mount /dev/nvme0n1p1 /boot/efi
Then you
arch-chroot /mnt
Then you are in the installed system and you can reinstall grub with the instructions and then generate a new grub configuration using the command.
sudo grub-mkconfig -o /boot/grub/grub.cfg
I think these were your partitions where you installed EndeavourOS. You don’t have a /boot partition so that step is skipped.
If worst comes to worse you could just reinstall. If i was to do that i would just boot on the live ISO and use manual partitioning and select and set the two partitions during the install process. That is also very easy. You just edit the existing partitions to set them as /root and also the efi partition as /boot/efi and select /boot in the lower window. Just don’t format the /efi partition just keep. Only format the /root to ext4 and the reinstall should work fine and pick up mint also which is on the last partition.
non arch systems have issues detecting archbased systen correctly for grub… because archbased use to have two initramfs lines and grub from non archbased systems does detecting it wrongly
trying the chroot alternative, says efi mount point does not exist.

Sorry I must have missed typing that. This was supposed to be a quick explanation but expected he would follow the wikki page but was having some trouble understanding it. Thanks for correcting my error.
Sorry about my quickly written instructions. The other grub error is just because you have the live usb still inserted when you updated grub. No issue there. Hope it’s working for you now.
so shut down, took out the usb and rebooted. on the grub menu chose endevouros. nothing, just a dead black screen. the linux mint does boot up, same as before.
also tried the reinstall option, chose manual partition, put in the mount points. do not see any apply button in the format window (there is a restore button though), and when i click the next button, nothing happens. should i try that again, and post what calamares is saying in the terminal ?
You boot on the live ISO. Start the installer. Use manual partitioning. Click on /dev/nvme0n1p1 so it’s highlighted and then click on edit. Look at the info. You can keep or reformat it fat 32. I said keep and you must flag it /boot/efi and in the box below that mark it /boot. Then select /dev/nvme0n1p2 so it’s highlighted and then select edit and reformat it ext4 and flag it /root and in the box below check /root. That’s it. Then click next and go through the install steps to select the online install of the desktop etc…
