I just fought with this for the better part of a week. Ours had M2 SSD drives, which I was never able to find drivers for. I ultimately found a thread on the HP Support forum that links to a download of a customized Win7 PRO installer that worked for me.

DO NOT open attachments or click on links from unknown senders or unexpected emails. Just got a batch of these in. No USB 2.0 ports. Boots to HP Sure Start. Have disabled the Sure Start stuff. Now getting to my Win 7 Enterprise ISO USB booting. Stuck at the language screen. Pretty sure I need to push some drivers into the Install.WIM. Like the USB 3.0 extensible drivers but what else may I need?
