Windows 7 fails to boot after 5/26/09 test updates

Hi,

I installed the Win 7 RC on my system a few days ago and ran into problems after installing the following three updates:

KB970421
KB970423
KB970424

I have done a clean install a couple of times and each time after these three updates are installed when the system reboots it goes into the Startup Repair wizard and detects the problem as:

"missing or corrupt ndis.sys"

I have tried doing a system restore to a point prior to these updates being installed but I still see the same error. If I disable automatic updates and don't install these 3 updates the system is stable.

Has anyone else run into problems with these updates?

Thanks,
Mark

Jeff,

Thanks for the reply. I can't get into safe mode. When I select boot into safe mode the Startup Repair wizard runs and I see the same error.

I am not too concerned about repairing this installation since it was a clean install and I can wipe it and start over. However, this is the 2nd time that these particular updates have caused this same issue so I am afraid that when I reinstall if I enable automatic updates the same thing will happen again.

Thanks,
Mark

Thanks Jeff, I'll give this a try and see how things go.

When you access the boot screen, choose Safe Mode with Command Prompt and you'l be able to run sfc there.

Thanks for the reply. I can't get into safe mode. When I select boot into safe mode the Startup Repair wizard runs and I see the same error.

This is a kind of contradictory statement.

I haven't had a chance to try "Safe Mode with Command Prompt" yet but when I do either "Safe Mode" or the normal boot sequence the Microsoft logo flashes briefly then disappears and the Startup Repair Wizard then runs.

I'll try "Safe Mode with Command Prompt" to see if I get the same result before I do another clean install.

Thanks,
Mark
