How to disable boot-window before system starts?

English Install/Boot/Login

Before system starts i can see window with few options: normal start, settings, read-only start. It takes 6 seconds from my system loading.
How can i disable this window to save 6 seconds or set timer to 0 and use hotkey for run this window?

Hi
You have posted your question in the incorrect forum, will move to install/boot/login. Closed for the moment.

Hi
Moved and reopened.

A couple of things I do, fire up YaST -> System -> Bootloader on the Bootloader options set the time to zero (0), uncheck the Probe Foreign OS and check the box Hide Menu on Boot.

The second thing I do is remove plymouth, lock the packages and rebuild initrd;


zypper rm libply-boot-client4 libply-splash-core4 libply-splash-graphics4 libply4 plymouth plymouth-branding-openSUSE plymouth-dracut plymouth-plugin-label-ft plymouth-plugin-script plymouth-scripts
zypper al libply-boot-client4 libply-splash-core4 libply-splash-graphics4 libply4 plymouth plymouth-branding-openSUSE plymouth-dracut plymouth-plugin-label-ft plymouth-plugin-script plymouth-scripts
mkinitrd
