When trying to Tails OS, a initramfs Buildbox prompt with the error aufs not found

After looking for this error, I found this mbusb/multibootusb#559 and https://gitlab.tails.boum.org/tails/tails/-/issues/17489

So, I tried to remove this option in config file and it booted !

Tails ticket is newer than the last config file modification, so I think that this config does not work since the Tails commit.

Thanks !

In the same way that MultiOS-USB supports memdisk and similar EFI based boot environments, can support also be added for Super Grub2 Disk (https://github.com/supergrub/supergrub and https://www.supergrubdisk.org/super-grub2-disk/)? EFI images are supplied which should be trivial to support but I am unable to implement. Thank you for your attention.

After installing to a drive from Linux and copying an ISO to the appropriate folder, my computer boots to a black screen. No messages, menu or other display at all. Secure boot is disabled. Other removable drives boot without issue. Can anyone suggest any troubleshooting tips?

Is it possible to boot undetected files such as a Windows 10 installation ISO? After placing it in the ISOs folder, only some Linux ISO's are detected and displayed. Is it a case of making a config file for the missing images or can I force GRUB to display all files found?

Please add if isn`t for BSD system booting

Usage: sudo $scriptname [options] device [data_size]

What options are available for the installer? I cannot find any documentation.

Tools -> Boot from Hard Disk.

can I add my own custom config?
if yes how?

I am trying to boot the latest Parted Magic ISO

Snipped contents of grub.cfg:

set default_settings=""
set live_settings="boot=live eject=no"
set linux="/pmagic/bzImage"
set initrd_img="/pmagic/initrd.img /pmagic/fu.img /pmagic/m.img"
set default=2
set message="Loading kernel and initramfs. Please wait..."

menuentry "1. Default settings (Runs from RAM 4GB+)"{
	echo $message
	set gfxpayload=keep
	linux $linux $default_settings
	initrd $initrd_img
}

This is what I am testing:

# For Parted Magic

iso_subdir="partedmagic"
iso_pattern="pmagic_*.iso"
grub_configfile=""

for isofile in $iso_dir/$iso_pattern $iso_dir/$iso_subdir/$iso_pattern; do
	if [ -e "$isofile" ]; then
		regexp --set=isoname "$iso_dir/(.*)" "$isofile"

		submenu "$isoname ->" "$isofile" {
			iso_path="$2"
			loopback loop $iso_path
			isocfg=""
			bootoptions=""
			linux_path="(loop)/pmagic/bzImage"
			initrd_path="(loop)/pmagic/initrd.img (loop)/pmagic/fu.img (loop)/pmagic/m.img"

			menuentry "Parted Magic - 1. Default settings (Runs from RAM 4GB+)" {
				echo "Loading kernel and initramfs. Please wait..."
				set gfxpayload=keep
				linux $linux_path $bootoptions $isocfg
				initrd $initrd_path
			}
		}
	fi
done

The ISO boots correctly and loads the above images.

Then it tries to load a .SQFS file which is the main OS in a compressed file. But it fails to locate it and drops out to a shell.

Frome there I try to locate the contents of the ISO but cannot find where it is mounted.

Any ideas what I can do to locate the file and boot?

ubuntu image file name:
ubuntu-22.10-desktop-amd64.iso

motherboard:
gigabyte z2709-D3

i installed certificate from EFI/BOOT/cert/MultiOS-USB.cer
Select Continue and confirm (Yes) key enrolling
but security violation error
i disabled secure boot but same error again

1. Three ISO files of linuxmint are correctly recognized.
2. Choose any file -> Enter -> Esc
3. Choose any file again, error: device not found.

How to fix it, thanks.

Nice project.
I see on windows_support.md that it says

Currently, you have to extract the files from the ISO image. In the future, we plan to run Windows directly from the ISO image.

How are you going to implement it? Any good ideas? I might be able to help you.

Hello and thank you for your usefull project !

I installed a first time my USB key on default fs, but Ubuntu complete iso is 5Go… So fat32 is not sufficient.

I installed the tool with ext4 and… the partition is now read-only, I can only write it with sudo rights.

Do you have any idea why ?

Command used to install the tool
sudo ./multios-usb.sh -f ext4 /dev/sdb 20G

Thanks !
