I've got something I've never experienced before.

I put a fresh image on a laptop. I had all the Windows Updates current, everything current, Windows 7 activated, MS Office 2013 Activated, Office Updates current, everything was working perfectly.

The only remaining thing to be done was a bottom case replacement because of slight damage in the corner where the AC adapter and WiFi switch is.

After replacing the bottom case the laptop is booting to a BSOD.

Since the CMOS battery had to be removed and moved to the new bottom case, the system date and time was off and had to be reset. I even reset BIOS to defaults.

Windows begins to boot for a second, then offers Startup Repair which fails. If allowed to startup normally, the colored flag begins to form in the middle of the screen, just for a moment, then blue screens, and reboots.

I tried to boot to our WDS server to reimage it again just for kicks, and it BSOD's even trying to reimage again.

I took it all apart again to make sure everything was right inside with all the connectors, and sub boards inside on the motherboard, put it all back together, same thing.

I'm lost now. It passes Dell Diagnostics with no errors.

Help!

This is common (and normal) if or when you change the BIOS Setup settings for the SATA Host Adapter: https://support.microsoft.com/en-us/kb/922976

To correct the problem:

1.) Run the download in the "Fix it for me" section of the above link

2.) Change the registry settings as shown in the "Let me fix it myself" section of the above link

3.) Change the SATA host adapter settings back to how they were set when Windows was installed (e.g. AHCI, RAID, IDE, etc.).

Let me know what you do and how it works out, Scott.

I will have to try something in the BIOS to allow it to boot to Windows before I can run a Fix it or make any registry changes. Right now, it does not even get to a log on screen.... :(

Ok. Update here......

A change in Sata settings put me on the right track.

I had not actually changed anything myself.

Having swapped out the bottom case required removing the CMOS battery. I started the "surgery" at the end of the work day on Monday and finished on Tuesday. Not sure that matters, but, the battery was unplugged a long time.

After plugging back in all the BIOS originally configured were gone. I even tried System Default which apparently didn't work either.

The SATA controller was set to RAID. I changed this setting to ACHI and I now have a booting functioning system.

Thanks once again Scott!!
