Did Lenovo update, Windows 8.1 won't load. BSOD

2014-07-29, 18:56 PM

I did an update from Lenovo which included video drivers, BIOS, and other stuff. Now my computer won't start. I get a BSOD and then the computer loops into the Automatic Repair menu (Windows 8.1). I did a System Restore Point and even though the OS said the recovery was successful, it still won't boot up correctly. Any help would be greatly appreciated.

Are you able to boot into Safe Mode? Does the BSOD name a driver file?

No. I try to go into safe mode and it BSODs out and back into the repair options. The BSOD flashes so quickly, I cannot read the error. I was able to try a restore point and it said it was successful but it BSOD on restart. I am just guessing...but I suspect it is the new BIOS version?

Okay, I had to video the BSOD error code because it flashed so quickly.

 

error: Inaccessible Boot Device.

 

This makes me think it is the BIOS. I will play with the boot order. I am guessing this is a result of the new BIOS Lenovo pushed to my computer via a suggested update. Anyone else have a suggestion?

This is a BIOS update problem.  I had this problem since I run my drive in RAID mode and the BIOS reverts it to AHCI mode after the flash.  It's a total mess.  I'll post a registry tweak that you need to do using the Windows boot tools later.  It has something to do with the Intel storage drivers.

Try this: https://support.microsoft.com/kb/922976

Follow the "Let me fix it myself" section and use the registry editor in the limited boot menu. I think you can open a console window and run "regedit.exe"

I believe in my case, I had to make modifications in the key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Iastor

System booted back right up after making the change.

I gave that a try. I was able to get to regedit (I didn't think it was possible) and I did follow the directions to the key. I don't have that last key mentioned. I also noticed the article was for Windows7.

 

I found a link on that same Microsoft page to a different way to solve a similar thing on Windows8. I followed the directions to get into COMMAND / DOS and get an elevated command prompt. I followed the directions to get the computer to restart in Safemode "bcdedit /set {current} safeboot minimal" and then followed the directions to type "shutdown /r /t 0"  to shutdown the computer and then start it back up. The computer didn't recognize the shutdown command so I hit exit. The computer went back into the Win8.1 repair menu. I chose to "shutdown" the computer. I restarted the computer and after approximaetly 10 minutes, it went into some sort of Safemode screen. The screen said "safemode" on all 4 corners but the desktop never fully developed. The screen flashed and I got the Lenovo splash scree with "Diagnosing your PC" again with the Windows8.1 moving cirle in the middle.  Now I am back to "Choose and Option."

 

I still can't boot. I am learning a lot about Win8.1 though...

Check in BIOS under SATA and see if it has indeed reverted to Compatibility mode instead.

The last part mentioned by ColonelONeill is critical.  In my case, I had to first set the registry value and then change the BIOS SATA/RAID value back to what I had set before the BIOS update.  The BIOS update reverted my setting from RAID->ACHI.  After doing those two things, I finally was able to boot up.  Also, I am running Windows 8.1 as well.  I forgot the exact key, but for what it's worth, IaStorA, iaStorAV, iaStorV all have it's "Start" value set to 0.

I went into regedit and made sure all those values (iastora, iastorav, iastorv,) were set to 0 (zero). They are already set to 0.  I was unable to find Msahci. I also did a "find" for it and it did not exist where the article said it should be. That article was for Windows7 and I am on 8.1.

 

I read the W530 user guide and it suggests the Serial ATA(SATA) be set to AHCI and that is how it is set now. The only other option is "Compatibility." I have tried both and neither boot up the computer. 

 

I still get the Inaccessible_Boot_Device error.

 

Can anyone with a W530 go over their boot priority list with me? I just want to make sure I have that correct.
