Ugh, this has taken me way too long to finally figure out/fix. I’ve been trying to wipe my Surface Pro 3 with TH2 – as I upgraded to RTM. However, I’ve had a bear of a time getting my USB key bootable.
Now, I’ve done it before, but for whatever reason previous ways haven’t been working. Turns out, there are 2 key things (one of which I was missing):
- GPT partitioning
- FAT32 formatting
To make it easier, you can use Rufus. Just make sure after you select the ISO, you reselect GPT and FAT32.
Once the key is formatted, you can boot from it either by restarting via advanced mode from within windows or by holding the volume down button when you turn it on.
*sigh* So much time wasted on this one.
