I have a Win7 64-bit machine …recently updated to the new version…
Since the next Boot …I’m Unable to Boot Back into Win7…
No Safe Mode… -Normal,with Networking,Command Prompt…None of Them…
booting with these causes it to load the windows files, then it gets to aswRvrt.sys
Google helped in directing me to know other user’s also have faced similar problem…
