chose the MBR of /dev/sda1.<br>

<br>
Is there a way to put a menu entry in Grub2 that would tell the system <br>
to boot from /dev/sda1?<br>
<br>
<br>
I did manage to create a menu entry in /etc/grub.d/40_custom that lets <br>
me load plop, but when I do, it gives me a warning that I can't save <br>
changes. Is there a way to fix it so I can save changes? Here is my <br>
40_custom file.<br>
<br>
<br>
#!/bin/sh<br>
exec tail -n +3 $0<br>
# This file provides an easy way to add custom menu entries. Simply type the<br>
# menu entries you want to add after this comment. Be careful not to change<br>
# the 'exec tail' line above.<br>
