I have installed Ubuntu 14.04 on a partition. Now I have Ubuntu and Windows 8.1 for dual boot. I followed this tutorial to install Ubuntu.
Now when I switch on the computer I have the following options in the grub.

  • Ubuntu
  • Ubuntu (advandced)
  • Windows Boot Manager (on /dev/sda2)
  • System setup

Is this normal? I mean, what is Windows Boot Manager? Should it say just Windows?
Why can I access the BIOS if I select System Setup?

As far as I'm aware, from my own experiences, yes it is normal for Grub to chain link to the Windows Boot Manager. Basically, it is the boot-loader that starts Windows, like Grub is the boot-loader that starts Ubuntu. The reason it is listed like that is because rather than starting Windows by itself, it chains itself to the Windows boot-loader so it'll do its job. You can access the BIOS anyways as that's overhead for boot-loaders and any operating system and is on the motherboard, not the hard-drive, where your operating system is from. BIOS stands for Basic Input Output System.

  • If I missed any information, didn't explain something properly, or am incorrect about a statement I made, please, let me know! I'll correct myself.

The System Setup is just a second name of BIOS setup. When you are in BIOS you see words in the title in there 'BIOS Setup UtilityorCMOS setup utilty` so it is all the same - BIOS, and it doesn't mean an installation of any OS.

If you don't like names in GRUB menu you can change them, you would need to operate via /etc/grub.d/40_custom and update-grub which will rewrite your /boot/grub/grub.cfg (don't modify this file yourself), but that's another story.
