Hmm, do you have in mind that the file perhaps is not fitting?

menuentry "Hyperbola GNU/Linux" {
    insmod ext2
    set isofile "/hyperbola-milky-way-v0.4.2-dual.iso"
    loopback loop (hd0,4)$isofile
    linux (loop)/hyperbola/boot/x86_64/vmlinux
    initrd (loop)/hyperbola/boot/x86_64/initramfs-hyperiso.img
}

There are many possible errors within this. Using that article perhaps can help: https://www.tecmint.com/run-linux-live- … -in-linux/

Nevertheless: Is the disk (hd0,4) existing? That would be also next to approve. But also to underline: You would to measure the settings for yourself as no one else overlooks your configuration better than you!

I have the iso saved on one partition and I'm trying to install to another partition.

Yes I understand that you want to install the OS. But foremost mounting the ISO on that way while accessing its contents at the same time won't work out from my current understanding. Maybe I'm wrong? The best way is to write the content of the ISO-file on a device of your choice and from what you have written you have already a disk ready. So it would be better to use a concrete USB-case.

You would need to have at minimum some data being accessed and using the loopback is from my current point of view not intended for this.

I didn't know that; I copied the grub entry from what I found online and I don't really know what's correct or wrong with it.

I'm trying to install the OS.

It is not clear for me what you want to reach with mounting the ISO-file alone. You would need to have at minimum some data being accessed and using the loopback is from my current point of view not intended for this.

The iso is slightly too large for my USB's storage capacity, and I don't want to buy another USB. There's no cdrom drive.

I've tried this custom grub entry:

menuentry "Hyperbola GNU/Linux" {
insmod ext2
set isofile "/hyperbola-milky-way-v0.4.-dual.iso"
loopback loop (hd0,4)$isofile
linux (loop)/hyperbola/boot/x86_64/vmlinux
initrd (loop)/hyperbola/boot/x86_64/initramfs-hyperiso.img
}

It boots, but drops to a rootfs session with the error "/dev/disk/by-label device did not show up after 30 seconds." In the folder /dev/disk/by-label is one file: System\x20Reserved.
