I have purchased two of these in the last few months .... Like them when they work .. but the first ceased to boot up after two weeks ... the second worked fine for three weeks then starting giving me a BootMng alert and I have a devil of a time getting it to just start ... I can't reach anyone a HP at all .... I don't have a startup disk (it didn't come with one) nor a stick ... issues with Windows 10 and license stuff ... I'm old (71) and don't have a clue what they are taking about so if you get one of these that works longer than a month ... You have a great machine ... I actually do Love this unit ... it's just that both of mine have failed within 6 weeks or purchase and I have no idea what to do ... I'm sitting less than 6 feet from a brand new (refurb to be sure) computer ... and it's useless in that it will no longer turn on, boot up, come up ... whatever the term is .... at the same time I ordered the first HP I also ordered a refurbished  Lenovo desktop computer that is functioning Perfectly .... No problems from day one ... It's a Super Machine ... I love my HPs but both have been a major disappointment ... I've used only HP for over 20 years ... but without support I'm through with them ... BUT if you get a unit that will continue to boot after a few weeks you will certainly not be disappointed with the HP either .... Raggy
