I am trying to install Ubuntu in a laptop with Windows 8.1, but after launching from a USB, I obtain the message “This computer currently has no detected operating systems”. I’ve seen a lot of similar problems in this forum, but all of them are solved in a similar way, as they are related with the UEFI or Legacy mode. However, my laptop had Windows 7 preinstalled, and I installed Windows 8 later, and when I try to modify these options in BIOS I don’t find anything related with UEFI or secure boot (I’ve already checked a lot of forums but I realized this option doesn’t exist on my BIOS). However I found strange that the USB is detected in BIOS as “UEFI: USB Flash Disk 1100”. Windows 8.1 is installed in Legacy mode, and the partition is MBR.
After a lot of time trying in this way, I created a partition (shrink space in Windows, there are also a lot of tutorials on how to do it in this forum) in order to install linux in that partition. However, when I click “Something else”, all the space is detected as free space. It is, there are no partitions. The only idea I have is to create the partition by using this assistant, but as everything is detected as free space, I will indeed lose everything I have in Windows.
Any idea? Thanks for the help!
