I have been trying to do it for hours now, but so far I was unable to.
I have a USB stick with grub4dos on sda1 (vfat), /boot syslinux on sda3 (ext2) and root on sda2 (btrfs). ext2 with syslinux is the boot partition.
There are two options in the menu: 1. Boot Arch on btrfs. This one works fine. 2. chainload to grub4dos (Easy2Boot) on sda1.
I had this setup working with grub2, but I now moved to syslinux, I can't get the second option to work. Here's the original working grub2 entry:
menuentry "Live ISOs"{
set root='(hd0,1)'
linux /grub.exe
}
Now, I tried to convert it to syslinux like so:
LABEL E2B
MENU LABEL Live ISOs
COM32 /chain.c32 hd0,1
APPEND ntldr=/grub.exe
but it gives me "ERR: Coudn't read the boot file"
Also, like so:
LABEL E2Bb
MENU LABEL Live ISOs
BOOT /grldr
APPEND root=/dev/sda1
but this doesn't give me even an Error. Just a screen flash and back to syslinux menu.
... and like so:
LABEL E2B
MENU LABEL Live ISOs
COM32 chain.c32
APPEND hd0 1 grldr=/grub.exe
of which the result is:
ERR: Option 'maps' requires a sector.
I think the problem is showing syslinux which partition to look for the E2B boot files, and also possibly the selection of the right file (grub.exe, grldr or something else), but I am out of ideas.
