My laptop was a work laptop which is not used now. It is in a domain and I don't know the admin password. I dual booted Win10 and Win7 and it was working fine until yesterday. After getting to the 'Choose Your OS' of Win10 and after selecting Win7. 7 boots up and when i login it says Service Notification Event Error and changes ti a black screen. Microsoft offers a hotfix but i need an admin password to apply it. I can't get to my company to unlock it. Can I remove the domain and get the admin password with Win10 somehow?
