Thanks for the insightful reply, I really appreciate it!
So I first go to your first link "here" and download the recovery image. I then follow their steps, get it onto a USB and reformat the Surface Pro, side question:
can I put it onto a 500gb external HD? I can reformat the hard drive.
Or do I download the recovery image from the first link, then use the MCT to the recover image onto the USB to reformat the Surface Pro?
Thanks again for the reply! I really appreciate it
The Recovery images are bare metal images... to factory default or equivalent depending on the version of windows in the image. With those you download the Zip file... extract it to a folder then copy the contents to the USB which should be formatted Fat32 NOT ntfs.
Boot the USB drive by holding the volume down button while powering on. Then chose the recovery option in the menu... remove everything.
You could make a 16GB partition on the HDD and it *should* work although I never tried it. Some USB drives can give you trouble booting because of other partitions etc., trouble copying files, or other issues.
The way to prep a USB drive ... you can use Rufus or Diskpart or strangely the MCT.
With Diskpart connect the USB drive and run DiskPart.
List disk ... look at the list and identify the USB drive.
Select disk # - where # is the number of the disk, usually 1 or 2 depending on number of drives installed.
Clean - Caution, this command will remove every partition on the drive and write zeros over the first and last megabyte of the drive... leaving in "clean" make sure you've selected the right drive.
Create Partition Primary
Select Partition 1
Format fs=fat32 quick
Exit.
Note: for booting on UEFI you don't need to make it Active or apply MBR info.
Go to the extracted directory. make sure hidden files are shown.
Select all then Copy and Paste them into the root of the USB drive.
With the MCT, it wipes, formats and creates a Windows Install USB so you just point it at the drive and go. It also has an option to Verify. Also use the 64 bit only Option. As a strange option, you could make a USB with the MCT then delete all the files and copy the Recovery Image files to it resulting in a properly formatted Recovery USB.
When you boot to the Install USB you would be doing a regular install just like from a CD or ISO.
Again hold the volume down button and press power on... release volume down after the Surface logo appears... follow the prompts once it boots.
There are a couple differences in what you end up with between the Recovery vs Install but not huge. If W10 was ever installed on it then it's already permanently activated so even if you installed W8.1 it would upgrade to W10 and activate with no issues.
