Windows 7: the boot selection failed because a required device is inaccessible

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 Windows 7 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:

HDDs
WDC WD10EARS-22Y5B1
Seagate ST31000528AS

SSD
FM-25S2S-120GBP2 - G.SKILL





Any suggestions?

Hmm, that looks rather choppy. Sounds like your disks have a physical connection problem. I suggest you check that.

Also, if the SSD seems to connect but the OS cannot be loaded, that would suggest that your bootmgr does not reside on the SSD.

Download an burn the bootable CD of Partition Wizard (last entry on the webpage). With that you can inspect your disks without the OS. Just load the CD.
