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:

HDDs

WDC WD10EARS-22Y5B1

Seagate ST31000528AS

SSD

FM-25S2S-120GBP2 - G.SKILL

Any suggestions?

Microsoft has posted a possible solution at Use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows

You can use the Bootrec.exe tool in the Windows Recovery Environment (Windows RE) to troubleshoot and repair the following items in Windows Vista or Windows 7:

  • A master boot record (MBR)
  • A boot sector
  • A Boot Configuration Data (BCD) store

To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:

  1. Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.
  2. Press a key when you are prompted.
  3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.
  4. Click Repair your computer.
  5. Click the operating system that you want to repair, and then click Next.
  6. In the System Recovery Options dialog box, click Command Prompt.
  7. Type Bootrec.exe, and then press ENTER.

I'll try it. I noticed when Windows 7 is initiated, becomes unresponsive in few time. Disk access not responds. –  Kiquenet Sep 14 '12 at 16:42

Have you moved the machine recently and perhaps dislodged a cable? I'd open the covers and check that everything is firmly seated. –  Nicole Hamilton Sep 14 '12 at 20:34
    
I check SATA cable (I connect disks to Channel 0 Master - SSD, and others in Channel 1, 2). If I use Live CD Ubuntu, I dont detect any problem, and I can copy files to USB HD extern. I'm confuse –  Kiquenet Sep 17 '12 at 20:52
