My XPS One 2710 (Win 8.1) was left powered-off (even power cord removed) for a week. Upon boot “no bootable device” appeared.
ePSA quick test, including the 1 TB HDD & 32 GB SSD cache disk, passed. Everything seems fine in the BIOS and in the Intel RST OPROM (acceleration maximized).
I have tried: set boot in BIOS to AHCI, reboot, and back to RAID, with no luck.
One of the last things I did before the error was a Windows update (which I guess causes 95% of my PC problems…). Could it be related to the Intel RST driver, or has the HDD failed?
Should I try to decelerate the SSD cache in the Intel RST OPROM? Any other suggestions?
