Steam OS Boot Loader?

[Ferret101]

I've been recently trying to install steam os on my dell optiplex 755, I use the dvd .iso and get through most of the installation but then i get stuck on a page that says "Install the GRUB boot loader on a hard disk. I'm very new with this stuff so what is this and where can I get it?

Here's some helpful info, I am shocked nobody else has replied to this, and you have probably already finished your installation, however just in case you still need the help, and just in case someone else sees this post and has the same issue:

Grub Bootloader is similar to MSDOS from waaaay back in the day. Back when your machine used to power on, and load MSDOS, from then you would have to type "win.exe" and hit enter to load Windows ME I think it was. Anyway what the "bootloader does is essentially, just initialize an operating system. A bootloader may or may not have a GUI (Graphical User Interface) to interact with, which means you would have to know the exact filename of the Operating System or Directory you want to run so you can type it in to load it. A bootloader is a common, and I believe necessary piece of software for Linux, Debian, etc based Operating Environments. You may also notice that consumers who have more than one single operating system on their machine, will be presented with an option as to which Operating Environment the user would like to load. This is a bootloader. Microsoft has a bootloader for all of it's Operating Systems; even Windows 10; however they have been reduced to a skeleton of their former selves from the 90's. Most people don't have to deal with a Bootloader unless you are running a Linux, Debian, etc based system, or have more than one Operating System installed. So let's get to the first step:

1. Ensure you have correctly prepared your installation media (Thumb Drive, Disc, Etc) as
per the instructions set forth by Valve here:

http://store.steampowered.com/steamos/buildyourown

2. Prepare your hard disk drive which Steam OS will be installed to, by formatting the proper
partition, or entire disk as preferred by user.

3. Install a Boot-Loader. Since Steam has specifically named a particular Boot-loader, I
would use that one for compatibility assurance. The Boot-Loader named "Grub" can be
found here:

ftp:/ftp.gnu.org/gnu/grub/

and instructions for it's installation and use here:

You will be installing Grub 1.9, the Legacy version. Version 2 is not necessary and may
not be compatible.

4. For safety reasons, please remove all hard disk drives from your desktop or laptop
EXCEPT the one you intend to install to. (Some users reported losing data on ALL their
drives during the installation process, and many laptops indeed have 2 SATA2 drives
accessible from the bottom of your unit).

5. Insert installation media and continue the steps you had attempted previously. Respond
here or by PM if you require assistance.
