Remove unnecessary Ubuntu startup options

Ubuntu10.04:

Modify the grub. cfg file instead of the menu. LST file.

Sudo Vim/boot/GRUB/grub. cfg

I blocked the startup Item of window 7. The file content is as follows:

#
# Do not edit this file
#
# It is automatically generated by/usr/sbin/grub-mkconfig using templates
# From/etc/grub. D and settings from/etc/default/GRUB
#

### Begin/etc/grub. d/00_header ###

Save_env prev_saved_entry

}

}
