How to create a Multi-Porteus Boot USB flash drive?
Hi everyone, it's been a bit since my last post...
Basically, I would like to achieve what I did a while ago here: How to use 'mkisofs' to create Multi-Porteus Boot ISOs (DVDs) (Post by ncmprhnsbl #80149) with DVD's - but this time with a USB flash drive.
I'm trying to install different versions of Porteus (3.1, 4.0 and 5.01) so that they can be booted from the same USB key. My boot USB drive (created with Porteus Installer from the 5.01 XFCE cdrom) works wonderfully well to boot 5.01, and now the challenge is to find a way to also boot the other versions from the same stick. I have tried putting separate directories (Por3.1, Por4.0, etc.) containing the "boot" and "porteus" folders in the USB key's root directory and playing with the porteus.cfg file in a number of ways, to no avail. In the case of the multi-boot DVD mentioned above, it was easily done by burning the DVD's with 'mkisofs'.
What's a good way to do this with a USB key?
Thanks...

How to create a Multi-Porteus Boot USB flash drive?
On the USB key you already have :
- /boot/syslinux/
- /Porteus
add :
/iso
(copy your iso into it)
you can add in (/boot/syslinux/):
/boot_porteus-3.1
/boot_porteus-4
/boot_porteus-5
(copy each content of their associated syslinux folder into it)
Next,
add the lines associated with each version
But modify them a little like this :

How to create a Multi-Porteus Boot USB flash drive?
A very interesting option Rapha.
So I better understand what you do; you extract from each ISO the whole /boot/syslinux/ folder or just the vmlinuz and initrd.xz files? And there are rarely modules in the ISOs /porteus/modules/ folder so is the extramod= cheat code necessary?
I multi-boot ISOs via grub2 menus.

@Rapha
Thank you so very, very, very much Rapha! It worked perfectly and it was *exactly* what I was looking for!
@Ed_P
I have experimented a little bit with Rapha's suggestion. It is sufficient to put just the vmlinuz and initrd.xz files into the /boot/syslinux/boot_porteus-x.x/ directories.
Also, the extramod= cheat code is not necessary, even if there are modules in the /porteus/modules folder: I have several in it and it loads them quite fine without that cheat code. Also, I did not copy any .iso, I just copied all the files in the Porteus isos (after extracting them) in their respective directories in the so-called iso folder in the flash drive root - it makes it easier to later modify everything as needed...
There is so much value in this forum, it is so great! You guys are great!!!

How to create a Multi-Porteus Boot USB flash drive?
Also, Ed_P, I know you have been experimenting a lot with grub2. Have you found a way to force a grub2 EFI build (and grub2 install to USB stick) when building and installing to flash drive purely from Linux? I have experimented a bit with grub2 (within Linux), and it seems to force an i386 (NON-EFI) build (and install) in the absence of an EFI partition. Do you think it possible to temporarily mount an EFI partition to fool grub2 into producing an x86_64-efi build? Not sure if it can be done... It would be very helpful when installing grub2 to removable devices...

Yes , indeed the other files are probably not necessary ...
"extramod= cheat code" is required with iso, since their module folders are empty and read-only
--> what's missing is an "extramod=" cheat code for optional modules
@cad
Please note that not all modules are compatible with differents Porteus versions.
Can you show an example of your Porteus.cfg ?

How to create a Multi-Porteus Boot USB flash drive?
A extramod= cheatcode is required for modules in folders outside the ISOs I boot, and to ensure there is no confusion to the ISO's /porteus/modules/ folder I name my folder with a capital letter, Modules. I do the same for Optional.
Added in 8 minutes 29 seconds:
No but i do have grub2 on one of my USB drives. I copied the Grub2Win folder on my hdd to the USB drive, which is formated FAT32, and it's EFI app to the EFI folder on the USB drive.

I never knew Porteus supported booting ISOs. Has it always done it or is it new with 5.0?

@Ed_P
For me "extramod= " is for modules loaded automatically on startup. I know that you can use the + sign to add the optionals in the module window,
but I'd like to know a solution for automatically assigning this optional folder with a cheatcode, but which one ?
in the Porteus 4 cheatcode.txt, there is already "from=/path/porteus.iso" :I never knew Porteus supported booting ISOs. Has it always done it or is it new with 5.0?
'from=/linux-ISO/porteus.iso' will attempt to load the Porteus
data from an ISO file placed inside the 'linux-ISO' folder.

You can also load all Porteus desktops in multiboot mode (for each version)
You must then move all the 003-[DESTOP].xzm modules from the "base" folder to "optional".
like this :
Then , edit your porteus.cfg like this :

Rapha, these are the first two entries in my porteus.cfg, which show my own application of the method you described:

The first entry refers to the original Porteus 5.01, with the files extracted (and unmodified) from the standard Porteus XFCE 5.01 x86_64 iso, which I left in the root directory of the USB stick - I saw no need to change that.
The second entry refers to one of my several custom Porteuses which reside in the "ISOS" folder (I do not use isos), which I placed in the root directory of the USB stick as per your instructions. Using your method, I can boot as many instances of Porteus as I like, and it works without a glitch.
Thanks once again for posting it. I had wasted a lot of time trying to figure it out and your response put a big smile on my face.

Ha! Thank you so very, very, very much, Ed_P!, for suggesting that thread. I have learned something important from it about grub2 security mechanism, totally new to me. I'll definitely give that Ubuntu method a try very soon and think it is the solution I was looking for to do it purely from Linux. Your approach with Grub2Win is also a good one as it gets the job done pretty easily. THANKS!!!Ed_P wrote: ↑05 Oct 2023, 15:56This thread might interest you cad.

How to create a Multi-Porteus Boot USB flash drive?

I've just discovered something important about using the Porteus modules activation panel and the link it has with the extramod cheat code setting (for ISOs).
If you make a path to the target folder of your modules and if it's terminated by a slash "/", the option + to browse your folders and select the optional modules folder will fail, as you'll only find the ISO folder, which is empty.
(* Information : on differents Desktop the option to select an extramod dir is not a +; but a black rectangle icon )
"extramod= cheat code" is required with iso, since their module folders are empty and read-only
--> what's missing is an "extramod=" cheat code for optional modules
For me "extramod= " is for modules loaded automatically on startup. I know that you can use the + sign to add the optionals in the module window,
