Getting error nvidia boot agent 249.0542 - Acer Computers & Internet

It seems the Basic Input Output System (BIOS) settings have been changed on this computer.

This type of error message occurs when the computer is trying to seek a network device to boot from, or is set to boot from a removable disc or other media that have bootable files stored on them that the BIOS requires prompting or selection for in order to proceed to the boot stage.

If the computer still does not boot properly repeat the above steps to enter the BIOS Settings/Setup again -> use the keyboard arrows to navigate to Boot Menu -> arrow down to Boot Device Order -> look at the BIOS Control Options at the bottom or side of the window to find the appropriate control keys for changing the order of the boot devices (often the + and - keys, the F5 and F6 keys, the Page Up [PgUp] or Page Down [PgDn] keys -> move/promote the Hard Disk Drive (HDD) to the First Boot Device position -> press F10 -> y for yes or press Enter for OK -> test the boot process again.
