Please help! PC stuck on "Please insert external storage media and press OK" error message

[Windows Central Question]

I tried to update Windows 10 but I didn't have enough storage so it made me use a flash drive to complete the update. I restarted the computer when it was done, and now it's stuck on a "Please insert external storage media and press OK" error message. I press OK over and over again but nothing happens and the message doesn't go away. I can't get to the desktop. Anyone know how I can fix this?? It happened in the middle of a big project I've been working on =(. Any help would be greatly appreciated!

Try booting in to your BIOS and changing the boot order so that your main hard drive is first, not your USB stick.
