Hello guys I got a rather simple question at first, but need confirmation why it happens, as I have been doing my fair search on google but it only shows people wanting to downgrade windows 8 to windows 7 -.-' Anyway the following is happening, i have 3 pcs here that i am working on, one being a desktop the other 2 being laptops, all of them have formatted hard drives, (2tb HDD for the desktop, 1TB sshd for the laptops) the hard drives are gpt and formatted as fat32, now the problem is, my desktop computer (which has an ami aptio uefi bios) can see the hard drive in legacy mode you can select it as a boot volume, obviously nothing happens since there is nothing there, but it can see the hdd, as for the other two laptops (they are both asus, one s46 the other s200ca) and the bios again are ami aptio uefi bioses on both, yet the laptops they can't see the hard drive on legacy, I can't select it as a boot volume. why does this happen? is it because of the bios? or is it something else entirely? does anyone have any clue on what to do to allow the laptops to see the gpt disks? thank you all in advance. EDIT since this has already more than 100 views and no replies, here is a too long didn't read, also i ll post pictures if needed. TL;DR: 3 different hdds formated as gpt 3 different computers UEFI bios in legacy mode recognizes one hdd, but not the others.
