I apologize for the title of the post, as I am not sure how to phrase it more precisely. Hopefully someone would correct it.
I have an SSD that has Windows 10 on it. I am going to remove completely Windows and install Ubuntu (perhaps another distro beside it, but no Windows). When I come to the partitioning part of the installation I am not sure how to partition the boot partitions. Grub, UEFI, etc. is all foreign to me. As far as I could tell I need to manually create partitions, but how many, what size, what type - that I couldn't find, or the explanation must have been foreign to me.
