I have a Liteon EP1-KB480 480gb m.2 ssd that I have been unable to boot from. I have tried it in various computers and it works fine as a separate drive but I have never been able to boot from it as a os drive with various version of Windows. I did have maybe two other similar ones that had worked ok. I am wondering if it needs a firmware update or reload but cant find a copy of firmware anywhere. Any help would be apreciated. Thanks.
