So my pc wont start it says no boost device found!... and i googled it and i did all the things that could be done on setup like changing the order of boost devices and ticking all the SATAs and still it wont start so the last option is to check if something is wrong with the hard disk... so my question is 1. Is there any other solution i should try and 2. Is it safe to mefetatat my pc by my own? And check if there is physical problem with the hard disk?
