Hello, I've just recovered from a "Windows Boot Loader" crash/error on my Windows Server 2008 R2 since then none of MMC snap-ins are working (you could see print screens below). What I've tried: 1. Run "sfc /scannow" - now errors were detected. 2. Tried this with no luck: "Navigate to C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG and Rename machine.config to machine.config.old" 3. Ran " .NET Framework repair tool" without success, it says "cannot complete repairs". 4. Used "System Update Readiness tool" no errors detected. Why the MMC snap-ins are crashing ? What caused it, don't understand how a boot loader error could create such a problem. Please give me some advice, need to solve this asap. Thank you in advance. Error screenshots attached.
