Win 7 boots randomly
I built a new pc with AMD fx8150 with ASUS M5A97R 2.0 .
I had never seen such a bios before with so many complications
(Compatibility Support Module /Secure Boot/Win UEFI MODE or Other OS/Legacy Mode/Both Modes/Load Keys/PK/KK/KEY Management... etc)
so loaded bios default and installed OS Win 7 Ultimate x64. (Bios showed 2 DVD drives in boot selection menu when i have only one).
I completed the installation and when rebooted the windows returned with error "disk read error occurred-press ctrl+Alt+del to restart) and this continues for 3-4 times and suddenly 5th attempt will boot my windows.
sometimes it will only boot after i enter the BIOS>Boot Menu>Boot Priority and select BOOT OVERRIDE option.
please help me out of this strange situation
(note: i was going through few article on web but they confused me more and more mentioning about MBR and GPT.. i am non technical person so its very hard to understand what they mean)
