Question about ISO snapshot

[Member madibi]

With antiX 17, I created an iso snapshot with some utility that I like.
That iso was put on a usb key and I still use it for a lot of purposes.

One of the main features that I like, is that with that key I can boot: pc legacy, pc uefi, mac (post powerpc).

With antiX 21 I made a key, hoping to be able to use it on any of the three systems listed above. Unfortunately, it only works with legacy PCs.

The old iso snapshot was done using an installation from an Acer desktop from 2007 64 bit, while the new one (the antiX 21) from an installation on an Acer aspire one D260, 64 bit.

Of course I would like to have an iso that I can use indifferently in any of the three systems.

Did I missed some step in order to get my goal?

Thanks in advance for some suggestion

Unless that utility that you like is antiX’s default snapshot tool, it may not work correctly (antiX Menu > Control Centre > Last Button on the left > “Purple” gears Icon)

I apologize, sometimes my English is inaccurate.
Of course in both cases I made the iso-snapshot with the antiX utility, and the reason I did it is because I wanted to have an iso that already had my gadget utilities already installed
thx for the clarification

As antiX 17 is a distant past for me I can only comment on antiX 21 and whether or not this functionality changed since I leave up to antiX experts…
– I am not clear what you mean by ‘put the Snapshot ISO in USB key’ but if you use Live-USB-Maker for this, i.e. you create antiX 21 Live USB using the Snapshot ISO as input, then this will create an antiX 21 Live USB, which should boot on both Legacy and UEFI computers. UEFI booting may require appropriate setting in BIOS as ‘Boot as Legacy First’ or you need to select boot device from BIOS menu.
– ISO Snapshot ISO is primarily a snapshot of your original installed system in squashfs file format. It is the Live-USB-Maker, which creates antiX Live USB, which can boot both Legacy and UEFI systems, using the linuxfs file, created though ISO Snapshot.

Experts – please correct and/or expand my above rudimentary explanation and whether this changed since antiX 17…
Thanks and Regards…

OK.
Now the question for me is clear.

I used Live-USB-Maker to realize my iso snapshot with antiX 21 (JWM)

In my case my iso snapshot boots only in legacy PCs.

According to you this is wrong (and it was my thought too).

Now I’ll do some tests to see the reason why

Many thx

If the .iso file was created with antiX 17, maybe it didn’t have the ability to boot with both options back then. Could you update it to 17.5, get it all up to date and then recreate the .iso file? Then, make sure your antiX 21 is up to date and use Live USB Maker to recreate the USB.

Basically I’m saying I think only the newer code has the choice to boot from EFI or legacy.
