It’s a single btrfs partition. Nothing else. That is the way manjaro has it configured during install of the OS. That means that grub is on there right?
Like I said:
so
parted --list
Please?
Alternatively, an inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
Just for elimination purposes I just tested clonezilla-live-2.7.3-19-amd64.iso and it was ok.
This was on ext4 though.
(also im sure menuentry "CloneZilla" without the ISO would make no difference)
Just tested it in a new vm with ext4. It works. Menuentry can have a different name. Even the location of the iso can be set. I used home/user/.

You should trust me a bit more…
That’s the worst place to put it. Please read this:
Especially the Linux has a hierarchical file system section.
I am aware. It was a quick test. Normally use /opt as suggested in the op.
No spare space… You’re in for a disk extension before doing this on bare metal. 
Alternatively, Parted Live and shrink one of your partitions to make space

Have 32 Gigs of ram so I disabled swap.
I have just noticed that my system uses mbr instead of gpt. Forgot to boot usb stick in uefi mode when installing system… Maybe that has something to do with it? I have no fat32 partition.
btrfs is fully supportet in actual grub 
even zstd-compession is now supported but only from grub 2.04 onward 
I do use this ! (on bare metal)
some things to look for: EFI - GPT - grub - grub-btrfs - btrfs(wiki @ kenel.org) - snapper - zstd - initramfs - mkinitcpio - mhwd-kernel
I did mark /boot to be NOT compressed by btrfs, grub.cfg is not compressed at alll. And kernel(gzip) and initramfs(zstd) are compressed, but not by btrfs. The rest is compressed with zstd=9
also look into this "emergency mode" after Timeshift snapshot recovery - #28 by gadzhi
The only feature missing:
What grub can’t do at this time is to store the last boot-entry on btrfs (GRUB_DEFAULT=saved does not work with btrfs)
Please have a look at btrfs send / receive
The name is irritating. This is a solution for incremental btrfs backup of snapshots
If you want to boot a iso from grub
, please put the iso under /boot/iso (and don´t compress /boot) There is an tutorial in this forum and additional info in arch wiki !
(When /boot is inside btrfs, you dont´t have a problem with the space there. So put things for booting there. And dont’ compress anything that must be used by grub)
And please allways install at least 2 kernels (one of them LTS)

Thanks for your reply. Don’t know if /boot is compressed in my case. How to find out? Could not find any answers. Anyway tried it with current and no luck.
You didn’t read the article did you?
That’s a whole different can of worms. Search the forum by clicking the magnifying glass in the upper right corner as:
You can’t seem to locate it.
I did and articles like that with another opinion before I made changes. Zero problems thus far. However to keep people happy I’ve changed it to:
~ sudo sudo sysctl vm.swappiness=10 ✔ NL
[sudo] password for magician:
vm.swappiness = 10
That is obviouslly not what I meant by that. I was referring to a command that shows wether or not the /boot is compressed.
Obviously using the looking class in the top right corner. 
~ sudo compsize /boot ✔ NL
[sudo] password for magician:
Processed 373 files, 290 regular extents (290 refs), 84 inline.
Type Perc Disk Usage Uncompressed Referenced
TOTAL 99% 109M 109M 109M
none 100% 109M 109M 109M
zstd 15% 12K 80K 80K
so your /boot includes a few compressed files (80k → 12k)
Than that’s probably the default behaviour.
Oh this may be default behaviour, but it will also work out of the box. Because it is used together with grub 2.04
Is it possible that your GRUB is older ? If yes, then look at Btrfs - ArchWiki (especially the warning)
please also read "emergency mode" after Timeshift snapshot recovery - #32 by andreas85
Nope grub is recent. Meanwhile I’ve installed latest manjaro xfce edition in efi mode with btrfs on bare metal computer. Still the same error messages. Tried both methods.
