I have tried several times to install Ubuntu on my laptop alongside Windows 10 as recommended in the Mag LINUX FORMAT but when I get to Installation type I only get /dev/sda and no other choice.
I have created an 80 Gb partition etc. but it doesn't make any difference.
The only issue I have had is that when I re-created the partition using gparted I got a message about 512 and 2048 that I didn't understand.
I have had another Linux distro installed before and it wasn't any problem to get it installed along side Windows 10 etc.
What do I need to do to solve my problem?
