Can't boot - OS Version Mismatch__

I don't know if this forum is strictly for the released version of Win7, but I sure would appreciate some help getting my Win7 RC working long enough to export my data and settings so I can import them into my retail version.  I've searched through all applicable posts on this board, but have not found any problems similar to mine.

I don't really remember now what preceeded this situation, so before giving all of the symptoms, let me first explain what I have done so far. One day I booted to the following message: (this is not a BSOD, it's white on black, and doesn't halt the processor)
File: Windows\system32\winload.ext
Status: 0xc0000098
Info: Selected entry could not be loaded because the application is missing or corrupt

Steps I took:
1. I booted off of the recovery media (also the tried original install DVD) - I get the "OS Mismatch" message (see below) - would not repair startup
2. Booted RM and went to command line to dig around.  Note: Bad Windows is my first partition, Good Windows is the second. Both are primaries so the booting drive is designated C: and the other D: - tryied SFC as well as replacing boot files - didn't work
3. I installed another copy of win7 RC into a 2nd partition on the same drive to compare files from a working system. - all boot files (winload.exe, bootmgr, etc appear to be the same, ie: not corrupt), and chkdsk shows good integrity.
4. Ran NirSoft's BlueScreenView to collect diagnostic info. NOTE: there is no minidump directory, so these logs are from D:\Users\Chris\Local Settings\Microsoft\Windows\WER\ReportQueue\Kernel_0_0_cab_04e0b75c

What happens now:
1. Boot - get OS selection screen (Good Windows, Damaged Windows)
2. Highlight "Good Windows" & F8 goes to Boot Mgr, boots ok
3. Highlight "Bad Windows" & pressing F8 or trying to boot results in the previously mentioned error 98 message.

From the diags I am guessing a wireless driver is the cuprit (but why am I getting the OS Version Mismatch message???).

If a bad driver is the only problem, how does one remove a driver from a dead OS?  Manually through the registry?

Anyway, here are the symptoms:

  Hi AzWiz,

The version of Windows installed and the version of Windows on the disc are different or is recognized as being different versions and that is why you receive the ‘OS Mismatch’ message.  You can try the following steps to resolve the issue.  Disconnect any additional hardware before completing these steps.

Modifying REGISTRY settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of REGISTRY settings can be solved. Modifications of these settings are at your own risk.

Note: Before attempting the following please do backup what data you can.

1.      Boot from the Windows 7 DVD and select command prompt.

2.      Browse to C:\Windows\System32\Config

3.      Rename the system and software files using commands:

ren system system.old (space between each word)

ren software software.old (space between each word)

4.      Browse to the C:\Windows\System32\Config\regback folder.

5.      Copy the system and software files using commands:

copy software C:\Windows/System32\config (Press enter)

copy system C:\Windows\System32\config (Press enter)

6.      Exit and reboot.

Can you boot into the normal Desktop or Safe Mode now? If this does not resolve your issue, try Startup Repair again.
