okay,
i expect that you installed mint on partition /sda2 and manjaro on /sda3. are i’m correct ?
what is the usb stick ?
Yes. Totally.
oh, nvm. it’s the file I transfer from manjaro to mint, and back and forth.
Now:

okay, before we go on. please copy/backup ALL important data (from your mint) that might get lost if the ongoing steps would fail in any way. better safe than sorry !
I just did a timeshift.
that won’t help you if the timeshift-data is on the harddrive. backup/save your personal data to the external storage that will be disconnected afterwards and cannot be wiped of.
oh, I understand. everything valuable is safe.
grub is pointing to a partition uuid which no longer exist.
This usually happen when you resize an existing root partition or if you delete the partition.
The partition has been deleted
This is caused by the previous failures - the system looking for a kernel on a partition that has been deleted.
You cannot have two partitions with the same uuid - this will inevitable cause errors.
I cannot say which one is the right one - but you need to fix the uuids.
sgdisk -G /dev/sda3
Be careful - check you have secured your data - partition operations are not guaranteed to be safe.

I am on mint now. Should I do something with gparted? You are talking to slow people, really slow. I resized a partition on Mint, but I always came back late, If I’m understanding you, wait, I don’t understand? I will try this. I wasn’t always there when the partitioning happened. Mint crashed? idk? after a few hours I came back, thought it was enough time and called that the partition. 
boot into manjaro-live, open a terminal from there and run the command from @linux-aarhus.
that makes sure that the drive is unmounted (because this operation must be executed on an unmounted drive).

I don’t understand what the uuid is. I got this
ohn@john-Aspire-E5-576:~$ sudo sgdisk -G /dev/sda3
[sudo] password for john:
Creating new GPT entries in memory.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)
The operation has completed successfully.
john@john-Aspire-E5-576:~$
okay, fingers crossed that it run well. please reboot and report if you have rebooted

will do. give me a minute
Okay, you are talking to a slow person, limited (if any) knowledge. I tried to boot from the Manjaro option, then I had no option. I will erase that partition and try again. I quit gparted too soon I think? I didn’t even notice what should have been obvious, panic and fear does that. I will erase and reinstall. Both mint and manjaro perhapse? The partitioning went wrong. You guys are just great, the best Linux ppl anywhere. I’ll lyk tommorow. You have my thanks.
well i don’t think that it went wrong because we still haven’t used chroot to fix it final but therefore all the steps till now are necessary to preparation.
before you erase everything, you’re only one step ahead.
please post the
lsblk -o PATH,PTTYPE,PARTTYPE,FSTYPE,PARTTYPENAME
again, that the identifiers are different.

okay, (even I) am noticing the problem, after it was explained. 
let’s try something (but it might break the system).
please boot into manjaro-live (the installation-media from where you installed manjaro).
once you booted, open a terminal and run
manjaro-chroot -a
after this run
update-grub
exit, reboot, fingers-crossed
This laptop has a catch; to make the option ‘disable secure boot’ visible you have to enter bios, open the ‘Security’ section and enter/create a supervisor password. Then disable 'secure boot.

Is this an iso that you burned to a DVD or thumb drive and you are trying to boot from it? If not, CDemu can mount the iso and run it as a virtual drive. More info is needed.
