And I wanted to know if it is possible to access to my Ubuntu system when I'm in manjaro via using chroot ?

Should be. Follow this guide and use the location of your Ubuntu root in place of location/of/new/root.

Sure. You probably have 3 options.

1. install manjaro-tools-base and use manjaro-chroot -a to get in.
2. Use systemd-nspawn -D /mounted/filesystem to get in.
3. Install arch-install-script, manually mount all the stuff a chroot needs and use arch-chroot /mounted/filesystem to get in.

So first, I need to mount all the disk partition ?

[techboy317]

Yes, then you should be good to go

What do you want to do after accessing Ubuntu?
If you just want to read, write, delete or add contents in Ubuntu partitions, you don't need to chroot into it. If you want to install, delete an Ubuntu application or system package, then chroot will not work.
