WD My Passport Ultra Metal 1TB

Can someone advise me a little as to the best way to do this on my Main machine. I suppose I should practice on a different machine, but here it goes.

I wonder which choice is better for the "Create a Windows PE Rescue Environment" as seen in this tutorial, the 4.0 or the 3.1?
Create a Windows PE Rescue Environment
This is a Windows 8 machine with Windows 7 PRO Installed in Legacy Mode I believe, I didn't do anything special during the Install.

Thanks, Nasty7

PE 5! HAHA, I didn't even see that. I looked at page 70 and didn't see this option, but will try to burn another with PE-5 if possible. I created the 3.1 and made a backup. Meant to leave this link above but it did not work. This is where I got the Directions to create the Recovery Media.

mjf, it looked to me that the drivers were Installed, am I incorrect? Maybe this is new since you did this that way, as it may or may not show at this link?
Rescue Media Wizard - WinPE drivers

There is nothing on pg70 about Windows PE?

I will check to see if I can see my new Image.

I pick pe 5 because of its usb 3 support.
From the user guide pg 70.

Again, I see nothing about pe5 on page 70, but it's all good as it seems all is working well.

Puzzling. When you boot the rescue disc/usb can it see images on an external connected USB 3 HDD?
Here are the pe options I get. You need to select change pe versions.

I just booted rescue disc and it saw the backup Image, so thanks very much pushing me to check it. I also just went and took a look at the "change pe versions" and saw the options you presented. This will be nice to know when I do my Windows 8 machine!

I wonder, and feel stupid asking, but I can use this drive to Image other computers also right? and files or folders as long as they are all created with Macrium?

Thanks again, Nasty7
