Some entries in menu.list causes grub4dos to hang

Hi all,
  I've noticed that on some setups, these lines in menu.list causes the system to hang at the message "processing the preset menu".

When I removed these lines:

Code: [Select]

title Boot from First Hard Disk
map (hd0) (hd1)
map (hd1) (hd0)
map --hook
rootnoverify (hd0)
chainloader +1
 
iftitle [if exist (hd1,0)/bootmgr] Load Microsoft Windows Vista/Win7/Win8 from First Hard Disk
root (hd1,0)
chainloader (hd1,0)/bootmgr
 
iftitle [find --ignore-floppies --ignore-cd /bootmgr] Find and Load BOOTMGR of Windows Vista/Win7/Win8
find --set-root --ignore-floppies --ignore-cd /bootmgr
chainloader /bootmgr
iftitle [find --ignore-floppies --ignore-cd /ntldr] Find and Load NTLDR of Windows NT/2K/XP
find --set-root --ignore-floppies --ignore-cd /ntldr
chainloader /ntldr
 
iftitle [find --ignore-floppies --ignore-cd /cmldr] Find and Load CMLDR of Windows NT/2K/XP
find --set-root --ignore-floppies --ignore-cd /cmldr
chainloader /cmldr
 
iftitle [find --ignore-floppies --ignore-cd /io.sys] Find and Load IO.SYS of Windows 9x/Me
find --set-root --ignore-floppies --ignore-cd /io.sys
chainloader /io.sys
 
iftitle [find --ignore-floppies --ignore-cd /sbin/init] Find and Boot Linux with menu.lst already installed
find --set-root --ignore-floppies --ignore-cd /sbin/init
configfile /Boot/grub/menu.lst

It boots fine.

I think this happens when there is something with the file system on one of the hard drives attached to the computer.

Is there anyway I can remove these entries as part of the build, rather than doing it manually later?

I tried removing the Plop Boot Manager, but that isn't it.

I found this thread, which appears similar.

Is there a way for me to remove these options in WinBuilder, or would I have to edit one of the scripts?
