SOLVED - No suitable video mode when booting Mocaccino Mate from iso on Usb

[fredmyra]

Hi!
I am trying to get acquainted with Moccacino OS and I have been able to boot the Mate version from an usb drive (made with dd) without any problems. Well, I haven' t been able to connect to the internet yet , but I have not tried it very hard yet.

I am now trying to boot from a copy of the iso made on a USB (pen)drive where I maintain several different isos of Linux, but I am getting the following result that stays on screen for a very long time (untill I give up and turn the computer off):
`Booting a command list

error: no suitable video mode found

Booting in blind mode

_`

When I first tried to install Grub to the MBR of the pen drive grub-install complained there was no EFI partition. After creating a 560Mib EFI partition I installed grub with:
grub-install --removable --target=i386-pc /dev/sdb

After that there was a file "/run/media/arthur/EFI/EFI/BOOT/BOOTX64.EFI".
I then made a custom grub.cfg:
`# dec 21,2022

Timeout for menu

set timeout=30

Default boot entry

set default=0

Menu Colours

set menu_color_normal=white/black
set menu_color_highlight=white/green
set gfxpayload=keep
set root=(hd0,msdos2)
menuentry "1 - Linuxmint-21-xfce-64bit-v2 botas"{
insmod search_fs_uuid
insmod part_msdos
insmod fat
insmod loopback
insmod iso9660
insmod ext2
set isofile="/ISOs/linuxmint-21-xfce-64bit.iso"
loopback loop (hd0,msdos2)$isofile
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile quiet noeject noprompt splash
initrd (loop)/casper/initrd.lz
}
menuentry "MocaOS Mate" {
insmod search_fs_uuid
insmod part_msdos
insmod fat
insmod loopback
insmod iso9660
insmod ext2
set isofile="/ISOs/MocaccinoOS-MATE-0.20220903.iso"
loopback loop (hd0,msdos2)$isofile
linux (loop)/boot/kernel.xz cdroot rootdelay=7 vga=ask
initrd (loop)/boot/rootfs.xz
}
`
and placed copies of it as both
/run/media/arthur/EFI/grub/grub.cfg
and
/run/media/arthur/Moca_milti/boot/grub/grub.cfg
where Moca_milti is the label of the root partition where the iso files are.

I was then able to start the booting process, with CSM enabled, but with error above.

Can you possible offer guidance on this or should I ask somewhere else (in which case I would be thankful for tips on where could I direct my question).

This problem was solved by adding
insmod all_video
to grub.cfg at the beguinnin of menu entry for MocaccinoOS
