Thanks. Tried two restore points... no change. Since I am now able to access windows via safemode, would you recommend running mwbamw and sas in safemode?
Before you do anything else, I strongly advise backing up the drive...even if you have to remove the drive and plug it in to a different computer (whether via USB, eSATA, or direct connect via an internal port).
If whatever software you are using is unable to make a normal image backup (e.g. using something like Macrium Reflect or DIXML (or even Windows backup programs)), then manually copy as many of the folders and files as you can, or copy those files/folders that are irreplaceable and important to you.
It's up to you how important your files are to you and how much effort you want to put into protecting yourself.
Even properly working repair, restore, etc. programs can corrupt or render irretrievable some or even all of the data on a drive if there is a hardware problem, or an unusual error during a repair/restore attempt. Or, the repair/restore operation might encounter a bug in the code due to a unique event during the operation.
Once you've got a backup(s) you at least have a better chance of recovering your data if something else goes wrong.
