Multiboot MX Live ISO Snapshot [Solved]

[thoro]

Dear forum

I was wondering if anyone has tried with success to boot an ISO image created by the MX-Snaphot ISO tool in a mutliboot environment.

I have created the ISO with the very last version of the MX live snapshot ISO tool (23.3) without changing any of the default options (eg compression = lz4) and have put it on sda11. Since I'm using grub customizer, I have added the following entry:

Code: Select all

menuentry "MX Snapshot 10.03.2023 (iso)"{
	insmod part_gpt
	insmod ext2
	insmod gzio
	set isofile=".iso/snapshot-20230310_1126.iso"
	loopback loop (hd2,gpt11)/$isofile
	linux (loop)/antiX/vmlinuz boot=casper findiso=$isofile quiet splash locale=de_DE locales=de_DE.UTF-8 bootkbd=de noeject --
	initrd (loop)/antiX/initrd.gz
}

where some of the parms were borrowed from a description for booting the gparted live iso (see here).

With this, I've already come around some kernel panic errors earlier, and have already come some way into the boot process. At this moment, I get to the following situation:

1678447706826b.jpg

Since I can verify inside the ISO that the file linuxfs is well present and located in folder (isofile)/antiX, I'm wondering what I'm missing to find/boot it. Should I change the ISO compression or load some other grub module (with insmod)?

I'd appreciate if somebody could please advise what needs to be changed.

Tx,

T.

Try without the "boot=casper" bit, which is typical of ubuntu variants (which MX is not)

Here's a working entry from my/boot/grub/custom.cfg file (not for a snapshot but a standard MX iso)

Code: Select all

menuentry "MX21 KDE" {
	set isofile=/ISOs/MX-21_KDE_x64.iso
	loopback loop (hd1,msdos17)/$isofile
	linux (loop)/antiX/vmlinuz bdev=sdb17 fromiso=$isofile hwclock=local quiet splash
	initrd (loop)/antiX/initrd.gz
}

The supported boot parameters are documented here.

[Huckleberry Finn]

Yep.

Btw. it would be more correct if you edit the title and change it to "... Boot From iso ... "

(... multiboot sounds like a question about Yumi or Ventoy etc.)

[Huckleberry Finn]

... also noeject is not needed (though it won't make any harm)

... and if it's sda11 : hd0,gpt11 (...on yours it's hd2 that means disk #3 partition 11)


... And the path:

.iso/snapshot-20230310_1126.iso


if you mean you created a .iso directory on sda11 then:

/.iso/snapshot-20230310_1126.iso

[Huckleberry Finn]

This will do the job for you (later you can add more options if you like.. )

( lang=de will already be enough (unless no timezone and keyboard stated they'll be considered DE, too) )

Code: Select all

sudo tee -a /boot/grub/custom.cfg <<!
menuentry "MX Snapshot 10.03.2023 (iso)" {
    set isofile="/.iso/snapshot-20230310_1126.iso"
    loopback loop (hd0,gpt11)$isofile
    linux (loop)/antiX/vmlinuz bootdev=/dev/sda11 fromiso=$isofile noprompt lang=de_DE ro quiet nosplash
    initrd (loop)/antiX/initrd.gz
    }
!

Reboot.

(It's normal that the terminal warns you about security, just click "paste" then press Enter)

Just make sure the path is exactly like this: snapshot-20230310_1126.iso file under .iso directory on sda11.

Hi,

your advise already helped me much further, thank you very much.

With the following custom script menuentry in grub-customizer

grub.png

I can already boot the live snapshot ISO with german keyboard, german timezone and german language. This is excellent

I am only struggling with the screen resolution, which is somewhat like 800x600 instead of the 1920x1080 I would like to have.

I am unsure about how to accomplish this. I would like to avoid setting or changing parameters "outside" the menuentry (which is the part I have easy access to in grub-customizer) and I don't seem to find the right value for vga= in the call of vmlinuz.

No more any relevant errors:

grup2.jpg

grub3.jpg

[Huckleberry Finn]

vga=791 ?

(why such a parameter?)

[thoro]

I tried 791 and 795, but neither one seems to have any effect; my wish is to reach 1920x1080, and this without touching grub's global variables outside the menuentry

[Huckleberry Finn]

Maybe 834 and 884 which are actually for 1400x1050 and 1600x1200

[thoro]

When I boot my normal live MX 21 system (NOT the snapshot ISO), and run

Code: Select all

sudo hwinfo --framebuffer | grep 1920

I get

Code: Select all

Mode 0x034d: 1920x1080 (+7680), 24 bits

which suggests that vga=845 would be the correct parameter to be used in my menuentry for the iso.

But its not the case: the ISO is again booted with a low screen resolution like 800x600 or so. Moreover, when I run the nvidia-settings, it seems the NVIDIA driver is not even loaded at all; I can also not change the screen resolution in the system settings, as there's only one single resolution available.

Any ideas?
