I have an Intel i5, Windows 7 Ultimate, and an SSD as my main drive and 2 SATA HDDs.
One day, I got a BSOD appeared and my PC restarted restarted. After that, the following error appeared:
Window failed to start. A recent hardware or software change might be the cause. To fix the problem: 1.Insert .... 2. .... ... status: 0xc000000e info: The boot selection failed because a required device is inaccessible
Also I noticed that BIOS only detected one of HDDs, not SSD neither other HDD.
Sometimes, Windows can be started, but it doesn't work very well. When trying to copy data from F: to an external USB, it copies for a short time and then Win7 becomes unresponsive. This also happens in safe mode.
After several reboots, now Windows will not boot and I get the error "The boot selection failed because a required device is inaccessible." And the BIOS only detects the SSD.
UPDATE: my disks:
FM-25S2S-120GBP2 - G.SKILL
