grub folder shall have x86_64-efi folder .efiboot.img and unicode.pf2 (all installed by grub or manually copied.

I have renamed vmlinuz and initrd.xz

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? :unknown:

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! :sos:

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