To prevent one or several operating systems from being booted from the boot menu,

add the entry lock to every section in menu.lst that should not be bootable

without entering a password. For example:

title linux

kernel (hd0,4)/vmlinuz root=/dev/sda7 vga=791

initrd (hd0,4)/initrd

lock

After rebooting the system and selecting the Linux entry from the boot menu, the

following error message is displayed:

Error 32: Must be authenticated

Press Enter to enter the menu. Then press P to get a password prompt. After entering

the password and pressing Enter, the selected operating system (Linux in this case)

should boot.

9.2 Conguring the Boot Loader with

YaST

The easiest way to congure the boot loader in your openSUSE system is to use the

YaST module. In the YaST Control Center, select System > Boot Loader. As in Fig-

ure 9.1, “Boot Loader Settings” (page 167), this shows the current boot loader congu-

ration of your system and allows you to make changes.
