I've always used:
https://wiki.archlinux.org/index.php/Multiboot_USB_drive
I created a big utility USB stick with it than can boot the
giant collection of ISO images I put on the stick. It can boot
either "normal" MSDOS or UEFI, but I've found a lot of computers
that don't like one or the other for some reason. I just boot
whichever version I can get to work. Here's my notes for setting up
the initial stick:
If starting from scratch, use gparted to erase all partitions
from the usb stick.
Create a 4 GB fat32 partition labeled BOOTUSB
Create an ext4 partition labeled DATAUSB in remainder of space.
Using /dev/sdc as the example name of the usb stick device, run these
commands to install grub on the BOOTUSB partition (taken from
the web page at
https://wiki.archlinux.org/index.php/Multiboot_USB_drive).
mount /dev/sdc1 /mnt
mkdir /mnt/boot
grub2-install --target=i386-pc --recheck --boot-directory=/mnt/boot /dev/sdc
grub2-install --target x86_64-efi --removable --boot-directory=/mnt/boot
--efi-directory=/mnt
At that step I end up getting the error message?
grub2-install: error: this utility cannot be used for EFI
platforms because it does not support UEFI Secure Boot.
Don't know if something change in the grub2-install that
causes it to fail??
Then not sure if get that to work, what would be the exact
format for the grub.cfg and where would be the spot to
put the kernel and ramdisk.lzma files?
Thanks for the input.
Now copy in the grub.cfg file (gets very specific to my case after
this).
