Unfortunately this only lets me post one image, here is the bios
I also have two entries in grub menu, unlike bios they have identical labels, however by pressing ‘e’ in grub menu was able to see that they have code which I unfortunately don’t understand. Second one was bigger and in addition to code in first one it also had
“insmod part_msdos
insmod ext2
if [x$feature_platform_search_hint = xy ]” … And a bunch of other stuff
I checked, both entries in bios lead to identical grub menu with those two options.
I will see if I can add new images by replying to this post. But based on that, which one should I use in bios and which one should I use in grub?
