So I reset my PC on Windows 10 and when it was done resseting it said "Operating System not found... Cntrl + Alt + Enter to reset"

So I looked up on how to fix it because Im not the best with computers and it said I had to enter BIOS. I tried entering it but every key on my keyboard wouldnt let me enter it..

I cant go on to Windows so I cant get it to work. I have a Dell OptiPlex 7010 with a Wired Keyboard Intel core i5. I downloaded Windows 10 onto a CD. If someone can help me thatd be amazing thank you.
 
It could be in BIOS, it could be the boot order, but you may need to reinstall the OS.

How To Fix "Operating System Not Found" or "Missing Operating System" error.

1. You will need your Windows OS (Operating System) CD or bootable Windows OS USB device.
2. Connect the bootable USB device or insert the CD into your computer.
3. Now use the "F2, F12 and Delete" keys enter BIOS setup.
4. Click "Repair Your Computer" below the "Install Now" button.
5. While you are in the "Repair Your Computer" open "CMD" (Command Prompt).
6. When you are in "CMD" type “diskpart” then type “list volume”.
7. Next you will be in "list volume". All volumes should be shown.
8. Find your system volume, where the windows are installed and then type “select volume ###“(system volume C) shows on CMD. Ex. select volume 3.
9. After you have selected the volume, type “ACTIVE“. Your system partition is active now.
10. Now type ”exit” to leave diskpart and then type ”exit” again to close CMD.
11. That’s it now RESTART your computer.

This should work, if you follow the steps correctly.
