Add an ISO file

[Tarq]

I tried this and it failed. I will try the unique disk code

[Tarq]

\boot\grub\loopback.cfg

Again, without seeing your grub2 parms I can't offer much help.

[Tarq]

I attached a grub file for the operating system that might be useful
note:
I think the correct one is /boot/grub/loopback.cfg

So which one of those 2 txt files did you use to get this msg: "No root device specified. Boot arguments must include a root=parameter."

Is the mx iso file in a folder on the drive? If so the isopath should include it. No need for the drive letter or drive name.

The /boot/grub/loopback.cfg does have 2 parmeters that you need to add to your bootparm settings. $root is created by g2wisoboot so that's no problem.

prefix='('$root')/boot/grub source'
bootparm= '$prefix'/grub.cfg'

What's missing is the $isofile in the bootparms.

File type located on a hard disk partition Disk image file (.iso) Target operating system MX-23.1_fluxbox_386 I did not mention the presence of an ISO file on a folder
The parameters and commands used are contained in a file --grubwork--cfg.txt
note:
I'm trying to install two different systems on two laptops

The grub2 parms in the grubwork--cfg.txt file you posted above won't work.

 set kernelpath='/** kernel path **'               
 set initrdpath='/** initrd path **'               
 set bootparms='** your linux bootparms **'

No vmlinuz file, no initrd file, no MX bootparms, no bootparm indicating your iso file.

If you're "trying to install" a Linux system you're in the wrong forum. Grub2Win is about booting systems not installing them.

Good luck Tarq.

The files are there, but I think the problem is not seeing the path to the original ISO file

So Tarq, did you get your MX ISO to boot?

I did, after many, many, many boots.

menuentry " MX 23.2 " --class custom --class icon-isoboot {

 set isofile='/ISOs/MX-23.2_fluxbox_x64.iso'
 set kernelpath='/antiX/vmlinuz'                 
 set initrdpath='/antiX/initrd.gz'             
 set bootparms='fromiso='$isofile' bdev=/dev/nvme0n1p7 ' 
 search -f $isofile --set=root
 loopback loop $isofile
 linux (loop)$kernelpath $bootparms
 initrd (loop)$initrdpath
}

The hardest parm to find and set was the bdev parm. It had to be specified else the ISO was searching for "USB,CD"s and it wouldn't accept the $root parm's value of hd0,gpt7.

I didn't use g2wisoboot cause my system is Windows 11.

**LOL ** I just reviewed the link I posted earlier. I used the wrong bootparm, Instead of "bdev=/dev/nvme0n1p7" I needed to use "from=all". I switched and it works.

set bootparms='fromiso='$isofile' from=all '

You're welcome Tarq.
