In netinstall, If I choose sysvinit, there's a question from where I will boot with options: (1) blank, you must specify yourself (2) /dev/sda (entire HDD) (3) /dev/sdb (installation media). I chose (2) /dev/sda, but when I finished installation, eject installation media and reboot, it didn't enter grub menu - but it entered BIOS menu.

What's wrong?

I finally enter grub menu successfully after I change the init to openRC. And that question didn't appear.
