Win 10 updates froze at 98% for hours and now will not load the os. I have (on any number of help boards) read for hours of similar problems and suggestions to solve the problem none have worked. I contacted Acer who provided the os as firm ware on the loptop. Acer was no help. I have been trying to learn about a bios option to use UEFI to load setup defaults but I cannot find out what those are and am not sure if I should proceed and what will happen if I do. Any help will be greatly appreciated.
