I have a NB, c:/menu.lst And a USB d:/menu.lst

I wish when I plugin USB, it boot from USB. When the USB plug-out, it .boot from c:/menu

So, I set c:/menu.lst as

title boot from usb find --set-root /usb.tag configfile /menu.lst fallback 1

title boot c:/ windows ....

What steps will reproduce the problem? When I boot from my c:/ without USB, it will failed on first title with error code 15.

What is the expected output? What do you see instead? I want it automatic jump to 2nd title.

What version of the product are you using? On what operatigng system? 2011-02-21 grub4dos-chenall

Please provide any additional information below.

Sorry, I've solved this by myself. The answer is:

I should put the fallback line on first line after title.
