I have two hard drives. One is used for Windows and one is empty. I want to install Ubuntu on the empty hard drive. The Windows hard drive is disk0 in Windows and the empty hard drive is disk1. When I install Ubuntu and it asks where I want to install it, I choose "Something Else" but I am stuck there. What do I choose for "boot loader installation"?

Put the boot loader (known as the GRUB) in the hard drive that you are installing Ubuntu on. If Windows is in /dev/sda put GRUB in the MBR of /dev/sdb. That is, do not put GRUB in /dev/sdb1 or another partition.

In the BIOS set to boot from the Ubuntu drive. This may boot straight to Ubuntu at first. If that happens open a terminal by pressing Ctrl+Alt+T and type sudo update-grub. From the next boot you should get the choice to boot Ubuntu or Windows.

Installing Ubuntu on 2nd hard drive, Windows on 1st

  • Unplug Windows hard drive.

  • Install Ubuntu on second hard drive.

  • Plug Windows drive back in.

  • Set Ubuntu hard drive as the first HDD in BIOS.

  • Boot Ubuntu hard drive.

  • In Terminal run:

      sudo update-grub
    

This should automatically add a Windows menuentry to the grub boot menu.

You can change back to Windows bootloader, (first HDD), using BIOS if desired.

I connected up one drive and installed Ubuntu. Then disconnected the drive. Then connected another drive and installed Windows 7. Then I connected up both drives and in the Bios set the computer to boot from CD as 1 then the Windows 7 as 2 and lastly the Ubuntu drive. Now when I start up it boots into Windows 7 without any menu. When I want Ubuntu as it is booting up I press F11 and choose the hard drive Ubuntu is on.
