So i want to install Ubuntu and im booting from USB. Im new to Ubuntu.
When i click SOMETHING ELSE, it shows 4 partions: the first of 1mb, sda1, unknown free space, second of 100mb sda2 (that i know its system recovery from win7), third is 170gb (win7) sda3, and the last one is like 830gb, i dont know where this came from.... on windows i have them separated.
is this a bug or something? How to install without losing all my data and keeping Win7?
When i try without installing i get to see my 3 partions (170gb, 600gb, 230gb) but not when i try to install.
Edit
ubuntu@ubuntu:~$ sudo gdisk -l /dev/sda
outputs this:

linux-swap
partition and its ownext4
partition. If you plan on upgrading, I recommend having a largeext4
/home
partition and a smallerext4
/
partition (like 20 GB). Good luck!
