I bought a new computer with a MSI x99S motherboard and SSD primary drive and Window 7 installed. On every first startup I get a text display stating no boot disk found. The work around is to bring the bios up (Click BIOS 4 version E7885121 V17.22B3(HM3) ) and exit. The boot order is correct in the settings. This happens every time I start up, I have to go into BIOS make no changes and exit which then goes to a successful OS boot. Something if fubar. OS disk is fine... Very frustration, I got to the point of just leaving it on but after a few days it crashes, so back to the bios boot nightmare. What am I missing?
