Windows 10: How do I restart my windows computer and select an operating system?

My computer was showing "Activate windows" on the monitor for a year now. To try and fix the problem, I added a new key in settings. The only problem was that it was a windows 10 enterprise key and I use windows 10 professional. My computer went into safe mode and resetting my computer or booting was not an option. I tried using the command prompt to reset my computer but I am unable to because windows needs me torestart the computer, select an operating system, and then select System Restore. I don't know what it means by restarting and selecting an operating system. Help is appreciated.

Hi Ibrahim,

Thank you for posting your query on Microsoft Community.

I suggest you to check if you are able to boot the computer into Safe Mode environment.

To use a Safe Boot option, follow these steps:

• 
  Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple operating systems, you can press the F8 key when the Boot Menu appears.
  
• 
  Select an option to “Safe mode with networking” using the arrow keys on the keyboard when the Windows Advanced Options menu
  appears, and then press ENTER.
  

Also, try updating your BIOS drivers and check.

Hope it helps. Do let us know if your issue is resolved. For any further query, feel free to contact us.

Thank you.

Ok. Now that you've made the change, the installer needs to be re-registered. Follow the instructions below right from MS:

Start your computer in safe mode, and then register the Msiexec.exe file.

To do this, follow these steps:
a. Click Start, and then click Turn off computer or Shut Down.
b. Select the Restart option, and then click OK, or click Restart.
c. Press F8 before the Windows splash screen appears.
d. On the Windows Advanced Option menu, use the arrow keys to select the Safe Mode option, and then press ENTER.
e. If you use a dual-boot or multiple-boot computer, select the appropriate operating system from the list that is displayed, and then press ENTER.
f. Log on to the computer.
g. Click Start, click Run, type msiexec /regserver in the Open text box, and then click OK.

Note For 64-bit operating systems, you also have to reregister the 64-bit MSI installer. To do this, click Start, click Run, type %windir%\Syswow64\Msiexec /regserver in the Open text box, and then click OK.

On 64-bit editions of the Windows operating system, 32-bit binaries are located in %systemroot%\SysWow64 folder. The 64-bit binaries are located in the %systemroot%\System32 folder.

h. Click Start, and then click Turn off computer or Shut Down.
i. Select the Restart option, and then click OK, or click Restart.
