What steps will reproduce the problem? 1. If an ISO or IMG etc file does not exist, it would be nice to suppress the whole menu entry for that ISO/IMG

e.g. if xx.iso does not exist do not list the entry in the menu.

if not exist /xx.iso skipentry title boot using xx.iso ffff (valid commands) ffff ffff

title boot to DOS aaaaa aaaaa aaaaa

2. 3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

This means you could have a large menu.lst containing many entires but just add the OS source files that you want and only valid menu options listed instead of all of them.

It's a good idea. can you please make a patch for it?

I've not idea for it.

I have found a way to do this using the current version by self-modifying the menu.lst - see http://www.rmprepusb.com/tutorials/57---automatic-grub4dos-menu So this can be closed.
