Thanks for your prompt reply, is this likely to change or is it dictated by thge 32k size limit?
Code that goes into core.img should be kept as small as possible. In your case using grub-mkrescue and placing grub.cfg there would be easier.

This is defined by normal.mod which is not loaded at this point.

That won't work using your command line anyway - you include neither search command not normal.mod.

grub-mkrescue does it for you and is guaranteed to continue to work if these modules change.
set bios=1 set efi=0 source ($root)/boot/grub/grub.cfg When I boot the iso in BIOS mode I get the following errors reported Unknown command ` if ' Unknown command ` search ' Unknown command ` source ' Unknown command ` fi ' Unknown command ` source 'Embedded config is processed using rescue parser which does not understand compound statements. This has been discussed just recently on help-grub. The guy intended to open bug report for misleading documentation but apparently never came around to do it.Can anyone help me with this I have tried every possible strategy and nothing seems to work. Currently the config file is set up so it falls through to the bios boot and the flags get set right and things do work but obviously this is not ideal.
