This is not really a question, it is more of an observation. I could not find an answer to my specific problem and stumbled on the solution after many hours of trial and error. I installed Ubuntu 20.04 on my Asus Laptop along side Windows 10. Things were running smoothly until I plugged in the USB Wireless Mouse dongle. After doing that, the computer would bypass the dual boot screen and boot directly into Ubuntu and not give me the ability to boot into Windows or enter BIOS update no matter how hard I tried. After unplugging the mouse dongle, everything returned to normal, the dual-boot menu returned and I was also able to enter the BIOS setup by pressing F2.

Edit - 2020/12/16 - As it turns out, my computer works just fine now with the mouse dongle plugged in. I ran several instances of boot-repair that did not correct the problem. Then I ran some scripts from this question in askubuntu - [Find (and reinstall) packages with corrupted files (without breaking anything)](https://askubuntu.com/questions/57682/find-and-reinstall-packages-with-corrupted-files-without-breaking-anything) to repair some corrupted files in install packages and another boot-repair and unplugged the mouse dongle and the computer booted normally. So I guess either repairing the corrupted files or the boot-repair or both corrected the problem and not unplugging the mouse dongle. Thank-you all for your assistance.
