Also, if you already have Windows, why would want SteamOS? It's not like you'll get money back or something...

You don't need to wait, really. I run OSX, Windows 10, PCLOS, Kubuntu and SteamOS on my mac.

I don't know how good you are with linux so I am going to try to make this newbie friendly.

Just download Gparted Live DVD iso and burn to disk and then Download SteamOS ISO, burn that to disk. Get a Kubuntu 14.04 Live DVD iso and Burn it.
Then find a usb HDD larger at least 90GB in size or a usb HDD dock/caddy.

(Optional Preperation Step if you don't have other PC or Smartphone to check email - turn off SteamGuard, the verifaction code expires too fast so you won't beable to log in on SteamOS)

Step 1. Open up USB HDD and place the HDD in your pc and unplug your Windows one

Step 2. Boot of the SteamOS install DVD and install it.

Step 3. Set up your account and login. Shutdown. Remove SteamOS DVD.

Step 4. Open your PC and remove the SteamOS HDD and install the Windows HDD. Putt the SteamOS HDD back in the Usb case and plug it in to the PC.

Step 5. Boot from th GParted live dvd, accept the apprpriate options for you on the menu. When you are in the Gparted live session you can shrink your Windows partition with the Resize/move option and click "apply", your NTFS partition will be resized.
Next make a root partition formated as ext4, SteamOS does 10GB but I find that to be too samall particularly if you want to install some stuff from Debian repos, So I made mine 29GB - label it "SteamOSroot". Next make a 10GB Ext4 partition for the SteamOS recovery, label it "SteamOSrecovery", make a Linux Swap partition that is half of your RAM size, and make another ext4 partition for home. Leave about 60GB free space for Kubuntu - this can be removed later.

Step 6. Still in Gparted, copy the "root", "recovery" and "home" partitions from the drive that you installed SteamOS to. Copy them to the repsective partitions on the hdd the you have Windows on. this can be done with copy and pastem, Gparted will make que of the actions. Click apply.

Step 7. When done reboot and remove Gparted and boot from Kubuntu Live DVD.
Install Kubuntu - we are only doing this to get GRUB working so that you can boot Windows and SteamOS. We are only going to need a root partition so choose "Custom Partitioning" and "add" when you are in the partitioning menu. Make one ext4 partition with mountpoint as root. Install GRUB to the sda or whatever is the name of the whole disk. Go through all the steps and finish the install.

Step 8. Reboot and load windows, you will need to run CHKDSK /r twice to fix the NTFS Partition because windows does not like being resized. Your Windows is good to go.

Step 9. Profit.
Reboot and you can now load SteamOS, login and install all your games. Re-enable SteamGuard.
If you want you could use Gparted to deleate the Kubuntu partition and resize SteamOS Home, but I don't recomend it as if GRUB has a problem booting SteamOS later having Kubuntu means that it is not too hard to fix.
