A client can't boot Windows 7 anymore
A blue screen rapidly appears and then disappears with the error c000021a (0xc000012f)
Tried a repair; restore isn't an option
I can't execute an in place repair because I can't boot into Windows
I can't run sfc /scannow from the Recovery section of the DVD setup
any ideas on how to get this system up and running again without a Windows reinstall ?
