Not all ISO files detected

JonnyTech commented 3 years ago

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?

Aha, I found the instructions for Windows 10: https://github.com/Mexit/MultiOS-USB/blob/master/config/win10_winPE/windows_support.md

How about other, non-dectected ISOs?

Also have one that shows message that it cannot start in loopback mode: Supet Grub2 Disk

Not yet. It is not that simple and it requires a lot of work.

That is correct.

Not all Linux systems allow booting from an ISO image.
Some just don't have the configuration ready - then you just create it manually and it works.
The more popular distributions are in the best situation. Then just load the loopback.cfg file from the ISO image and everything works.

can I force GRUB to display all files found?

This does not make sense. Displaying the ISO name in the GRUB list is not enough. Read above.

There are 2 possibilities. The first is "temporary" as it may not work with a newer version.

If possible, you can manually create a configuration file
Request support for "loopback" or send ready-made code to the distribution developers to add support for this feature.

Super Grub2 Disk has similar functionality to MultiOS-USB. This is probably why. As far as I can see, it is no longer being developed. Theoretically you can load the sgd/main.cfg file and it should work.

I have not figured out how to make an ISO load a configuration file. Do you have a newbie tutorial?

Grub loads the configuration file from the ISO. Menu example

I don't, just the internet and analysis of ISO images.
