I am a newbie. After downloading the latest version http://download.gna.org/grub4dos/grub4dos-0.4.3-2007-12-25.zip, I found that it doesn't work with my Biostar 945GZ motherboard: After booting from the USB flash drive and loading GRLDR via NTLDR, the built-in menu.lst is automatically executed (is the built-in priority?), but \menu.lst didn't work. When running the root (hd0,0) command in the command line, it prompts Disk read error. I tried a version from June and it worked, but I don't know why? However, the latest version works perfectly on my HP 6515b notebook!
