Essentially, what occurred was that the individual was utilizing Windows 10 on an Acer Predator G9-791 computer and made some changes in the BIOS. They switched the boot mode from UEFI to Legacy and restarted the laptop, but were only able to see a smaller logo during the boot process that read “(Acer Predator image) Predator,” with nothing happening afterwards.

The issue is that they cannot switch the boot mode back to UEFI, and are unable to access BIOS using the F2 key, despite trying different keys such as del, esc, and f1-12. They need help on what to do. Additionally, when they removed the SSD with Windows, the computer booted to some sort of terminal and continues to display a message:

Intel UNDI, PXE-2.0 (build 083) Copyright (C) 1997-2000 Intel Corporation.

For Qualcomm Athernos PCIE Ethernet Controller v2.1.1.5(03/15/13).

Check the connection! PXE-M0F: Exiting PXE ROM. No bootable

device — insert boot disk and press any key

TL;DR: After changing my boot system to legacy, I am no longer able to access BIOS.
