This script was auto generated by grub to use porteus.cfg. Enjoy both grub and syslinux boot loaders.Place grub and syslinux folders in /boot.

Ed_P,
A few days ago, I put up grub-2.06 module for download. Move and Activate.
open terminal,
Code: Select all
grub-syslinux2cfg /mnt[/sdxn/boot/syslinux/porteus.cfg
Your main boot code is ready. i.e grub.cfg
I would have added few other lines at the top in the grub cfg., manually, to represent grub style.
grub folder needs to have those three files/folders, given in the last line. (look for those in /usr/lib/grub folder or in /usr/share)
It copies few modules from the xxx.efi folder during boot.
That is it...Cheers.

Where is the grub.cfg file?
And why the UNSUPPORTED commands?

Unpack archive, and put grub folder inside boot folder, in your USB disk with grub boot loader.
Since we have used /boot/syslinux for vmlinuz and initrd.xz, location, keep them there.
When grub shows your porteus menu, smile and bite into a chocolate bar.

If you want porteus.png, please change resolution to 640x480 in the menu or resize picture to 800x600

Thank you raja. I think I'm beginning to understand. Your grub-2.06.xzm is designed to add grub2 support to a bootable Porteus USB drive that is booted. I have a grub2 bootable USB drive and I'm running from a booted Porteus ISO file.
It's too bad the grub-syslinux2cfg command doesn't accept a -o command.

Well there's a way to avoid booting issues when simply trying to evaluate a fresh-new release, just to decide what's the next step (...):
https:// www . osboxes . org / virtualbox - images/
And i actually expected to find Porteus listed right there as well- but somehow didn't!

And that works but it wasn't built from /boot/syslinux/'s porteus.cfg which is what
raja's grub-syslinux2cfg command can do.
