Unable to boot into Windows Vista after uninstalling Service Pack 1 Beta
Posted on 2008-06-21
This is my first question here....
My system information should be attached. I have a HP HDX9000 Laptop with Windows Vista Ultimate 64-bit installed (factory preinstalled). I have had the laptop for about 6 months, so reinstalling Windows isn't really an option. I downloaded and installed Windows Vista SP1 Beta some time back (I think it was v.664). Anyhow, yesterday a message appeared stating "Your Windows license will expire in 10 days. Please back up your files and install any version of Windows Vista." With an OK button on the box. So, I read a bit and found that it was actually SP1 expiring. I installed it so long ago, I was hesitant. But I tried to install the network install version of the Final SP1 and it said "SP1 is already installed."
So, I proceed to Add/Remove Programs and choose to uninstall SP1. It took some time, rebooted, and then seemed to continuously reboot a few times. So, I hit F8 and chose "Disable Automatic Restart on Windows Failure". Here's what I've got:
STOP c0000139 Entry point not found
The procedure entry point NtRenameTransactionManager could not be located in the dynamic link library ntdll.dll
Safe mode without networking produces the same result. I do have an ERD Commander disc that I could use, but don't know what I would do. Should I try to replace the ntdll.dll file with the one from the final Service Pack somehow? I do have another Vista 64-bit desktop, but have NOT installed SP1 of any kind on it as of yet.
Thanks for any help provided!!!
