BSOD When moving old HD from Dell 690 to HP Z820 and trying to Boot in legacy

Sluggobubba used Ask the Experts™
My apologies, but I have not found other articles covering this.  If I missed something that was already posted I would appreciate any links.


Old - Dell Precision 690 Worksation - SATA II HD with WIN 7 Pro 64 bit OS - legacy BIOS
New - HP Z820 Workstation - 1TB SATA III HD x3 setup in RAID 5 config - UEFI + Legacy BIOS

To move the customized Windows 7 pro 64 bit image / HD to the new Z820 RAID 5

What I have done:

I moved the physical HD from the old Dell system into one of the free SATA controller slots on the Z820's Intel SATA controller.  I of course was unable to boot since the default BIOS setup was for UEFI boot(HP support walked me through setting up legacy support for the HD).  

This is where I had some issues, I needed to change the SATA type to IDE in order for the HD to be recognized, then install the latest HP driver for Intel Rapid Storage on the HD.  This worked and we progressed to being able to boot in AHCI mode.

The final step is getting the HD to boot in AHCI + RAID mode in order to see the RAID 5 and be able to Ghost (my only experience is using Ghost) the image to the RAID.

When we switched the mode to AHCI + RAID, we get a BSOD after the Windows 7 splash screen shows up:

0x0000007b (0xfffff880009a978e8, 0xffffffff0000034, 0x0000000000000000 0x0000000000000000

My helpful HP technical support guy said this was related to the controller not recognizing the HD.  He recommended I change some registry settings to help the OS recognize the new controller drivers:

HKLM\sys\ccs\serv Iastorv value set to = 0

HKLM\sys\ccs\serv MSAHCI start value set to = 0

This did not work either and we have spent two days trying variations of the same procedures and have come up empty.

He is convinced that the driver for the Intel Rapid Storage Technology is the cause of the BSOD, but we cannot seem to shake it.

I am hoping that someone can suggest how to fix this issue or suggest another way to move the image from the old HD to the RAID.

Thanks for any help!

The 07b error is, as your HP tech said, most likely a controller error (Strictly speaking it's an inaccessible boot device), you should be able to add driver support for the HP's C600 AHCI/SATA controller by installing Intel's driver with the drive booted in the Dell but there may be a bigger issue here if the Dell system is running Dell's OEM version of Win7 Pro which will only run on Dell hardware.


The Windows installation is Customized from a standard install, not a Dell image.

So you are saying to install the Intel Rapid Storage Tech driver while the drive is booted in the Dell?  Won't it require seeing the controller before it will complete the installation of the driver?

That being said, the driver installs without error when I boot into IDE and AHCI mode(on the z820), but not when I boot into AHCI + RAID.  That is the only time I get the 7b error.

The RAID boots just fine (Windows 8 64bit VAR build) on its own, and recognizes the Win7 build as a slave, just not the other way around.

I have not tried a repair yet because it will boot in two of three available SATA modes.

IDE and AHCI work

hmmm... sounds like the raid controller from the Dell 690, wrote some info to the array, and now the HP Z820 raid controller is basically "choking" on it.
But my raid knowledge is not advanced enough to know for sure.

A repair might help. So either have a good backup, or try it on cloned drives, first.
So if you build a new version of windows on a local disk it boots, but doesn't  off the RAID? And the windows config on the RAID was built for another machine (different vendor) so it might have lots of drivers installed that don't support this new server.


Sorry, let me be very concise.

There is a Single SATA II HD with win 7 pro 64 bit on it
There is a RAID 5 (3 STATA II Drives) with Win 8 pro 64 bit on it

They both are currently connected to the same Intel disk controller in an HP Z820.

I am trying to get the win 7 pro 64 bit build on to the RAID 5

The win 7 build boots in IDE and AHCI, but BSOD when I try to boot in AHCI + RAID

The RAID 5 boots just fine

The end goal is to get the current Win 7 pro 64 bit build imaged to the RAID 5 and replace the Windows 8 build.

I have installed the Intel Rapid Storage Driver (the same one that is installed on the RAID 5 Win 8 pro 64 bit image) on the Win 7 HD.

This is NOT, a new fresh Windows 7 build.  This is a working Windows 7 build that we are trying to migrate from a Dell 690 to an HP Z820.
Dude .if the old system boots,get a eval of Symantec System Recovery 2013(60 days) ,install it.

Back it up to a USB disk and restore to the new raid 5 system using it's universal restore.
It gives you the option of installing new device drivers that support the new hardware.

By the way,Intel Rapid Storage RAID sucks,so you have been warned.

But that is the problem it ISNT a version of windows built to run on a HP server, it doesnt know about HP specific hardware built into the HP server. HP traditionally build their own RAID controllers, so its likely that the RAID drivers in your Dell build will not interface with the HP RAID controller hardware.

You need to adopt this system to new hardware simply. Use P2P Adjust OS wizard from Paragon Boot CD which is available in Hard Disk Manager 14 Suite:
It will let you install the necessary driver while yet being in Boot CD mode. Also it will automatically disable the unnecessary drivers so that you do not get a conflict in drivers.
Did the version of W7 you have come with the Dell?

If so ,you may have activation issues when moving to the HP.

Also ,a lot of image based restore programs are not supported with Intel "fake" RAID.
Thanks to those that attempted to help.  None of the posted answers actually solved the issue.

I did find a workaround.

I used a bootable Ghost disc to boot and imaged the drive (with the storage controllers drivers already installed), directly to the RAID5 volume.  When I did that, the RAID booted correctly with the Windows 7 image working.

The only caveat I would add is that the single SATA volume was never able to boot directly when the SATA mode was set to RAID+AHCI, even with the correct storage drivers were installed.


I've requested that this question be closed as follows:

I was the only person able to find the workaround.
Nobody suggested Ghost, but the apparent "solution" was related to RAID drivers which had been suggested by different experts.

No, the RAID drivers were ALWAYS there, from the beginning.  Please read the entire post before you comment.
