BSOD after Dell Raid controller upgrade

I have a Dell PE server which has a H200 raid controller in it with 2 x 600GB SAS drives in raid 1.

I have struggled with disk performance and after doing a lot of reading found that i would get some performance improvements from upgrading to a better raid card.

I ordered a Dell H700 card and attempted the upgrade tonight.

The instructions were as follows:

Power down server.
Plug in new raid controller into server in a spare pcie slot leaving the H200 in place with drives attached.
When into windows (SBS2011) load the latest driver for the H700.
Power down server.
Take out H200 and put in place the H700 and attached drives.
Boot server and go into raid controller.
Import foreign config.
Save and reboot.

Now to this point everything went well.

When the server tries to boot into windows it gets to the splash screen with the horizontal bar and then blue screens.

I have now gone back to the H200 but the raid has been wiped out so im now running without raid.

Any ideas on what i did wrong or how to resolve the BSOD?
