Today you turned on your computer after being on vacation for a week. You see spinning white dots on a black screen. You decide that an update might be installing, so you allow the computer to work for approximately 20 minutes. After 20 minutes, you turn off your computer and then restart it, and it fails two more times.

A. Use BIOS to see if the hard drive is available.
B. Use Safe Mode to boot.
C. Use Startup Repair.
D. Run sfc /scannow for Windows RE command prompt.

C. Use startup repair

Explanation:

to fix startup stuck on the spinning circle in Windows 10 is to press the Ctrl+Alt+Del keys simultaneously. It would bring up the login box. A system restore rolls back your Windows 10 to the point when it was in a normal state. Hold the power button to hard shutdown your PC

- from my experience in BIOS and dual booting, B. will have nothing to do with the problem as its just a precaution, so a malicious program cannot run at boot. A. it is plausible, ask the customer(s) if they have attempted to boot from another drive(or they could of disabled, windows boot manager), And for D. its not possible since you cannot get to cmd(command prompt), which leaves us with C. the most common way to fix this very common problem.

- BTW: Learn PowerShell instead of cmd, its what is becoming industry standard!

the omega button is one of them.
