I used menuentry (code below), but distribution did not boot.

menuentry "Arya install" {
insmod loopback
set gfxpayload=keep
insmod gzio
insmod part_msdos
insmod ext2
insmod xfs
set root = hd0,msdos10
set bootpart=uuid:ab6c94ab-6337-4eb0-9e2b-4f1919411067
set isofile=arya.iso
loopback loop (${root})/${isofile}
linux (loop)/isolinux/vmlinuz automatic=method:disk,${bootpart},directory:/${isofile} ramdisk_size=183210 changedisk lang=ru_RU splash noeject xdriver=auto quiet=1 showopts
initrd (loop)/isolinux/initram.fs
}

Hello and welcome to LQ.

Let's start by asking where did you get the idea for making that menuentry?

How do we know for sure a number of things like is iso OK/Tested and does your grub 2 have full support for your devices? Does your grub load other things.

Some examples of other distro's examples http://git.marmotte.net/git/glim/tree/grub2

Describing the failure in some way also may assist.

Hello.

>where did you get the idea for making that menuentry?
From linux mint.

>is iso OK/Tested
Yes, it is OK, when i add it to Virtualbox CD-ROM.

>does your grub 2 have full support for your devices?
I don't know.

>Does your grub load other things
Linux Mint 18

When I testing menuentry like this:

menuentry "AryaLinux Mate 2016.08" {
insmod part_msdos
insmod ext2
insmod loopback
insmod iso9660
loopback loop (hd0,msdos10)/arya.iso
set root=(loop)
linux (loop)/isolinux/vmlinuz inird=initram.fs
initrd (loop)/isolinux/initram.fs
}

Monitor shows:
Loading AryaLinux.. Please wait.
FATAL: Boot medium not found.
sh: can't access tty; job control turned off

I'm not 'heavy' on this, but here's a couple ideas: [I searched your whole loopback line]
http://askubuntu.com/questions/50029...from-grub-menu

I'd advise learning to use *grub's* `ls` (after using 'c' to get grub> command prompt)
to look for your "Boot medium". There's probably better terms, I searched: grub ls tutorial
http://www.linux.com/learn/how-rescu...g-grub-2-linux

I know zero about 'loop', but maybe research that (add it to search); here's a 'messy' one:
http://forums.mageia.org/en/viewtopi...=11364&p=66190 (might not be relevant: I don't know)

I'm wild-guessing you can do/simulate all this in VirtualBox (hmmm, a project for my studies!)

Maybe describe more about your 'distro' (the one you run, not Arya), (its working) grub.cfg, partitions, etc...
