Upgraded laptop online to Windows 10 (previous 7 pre-loaded) 3 weeks ago. 2 days ago started pc, got BSOD Recovery Screen with info: System32\drivers\WRkrn.sys Error code 0x000007b) I do not have a recovery disc or flash. WHAT Do I do?I had someone reinstalled my win 7 which was pre installed when I originally bought laptop. This person added this Webroot Anywhere & this is the reason I am having error msg. I have no idea if or how he registered this. The BSOD says F8 but when I go to other screen it won't let me use any options listed. I can't boot in safe mode, command prompt or anything except BIOS unless I haven't tried holding down shift key yet. I doubt that will work since the macros aren't working. Please help!!!
