I'm missing my Operating System after a BIOS update from ver 1805- 2014 . I have a P8Z77-V PRO motherboard, LGA 1155,Intel i7 3770k@ 3.50Ghz ,Ram 16384 MB DDR3 1333MHz and two x 1TB hard drives with one RAID configured. I'm stuck in the ASUS UEFI BIOS Utility - EZ Mode screen.I have no clue how to reset the boot configuration to what it was before. Please anyone with technical know how to resolve this, will greatly appreciate . Thanks.
Hi, In BIOS, Advanced mode, Advanced menu, SATA Configuration, set SATA Mode Selection to RAID.
