Something has gone very wrong all of a sudden. I have been using the First Defense-ISR for quite sometime. This has enabled me to create several snapshots for testing purposes. After having problems getting into one snapshot earlier today, i.e windows hanging at "Loading Your Personal Settings", I thought I would try a chkdsk /f in another snapshot. It seemed all was OK, because the system continued, but all that then happened was a BSOD which indicated "Sessions_Initialization_Failed. Trying to boot into this snapshot in safe mode has failed , also. So after having 3 alternate snapshots installed with WSA, I am now down to my remaining accessible snapshot. I think some change has occurred with v8.0.025 that has led to this problem of (now) unbootable snapshots. Joe, I hope you can suggest a way to fix the situation. Perhaps a remote session?
