I recently installed Ubuntu 16.10 on my new laptop, alongside the already installed Windows 10, using this site : http://www.tecmint.com/install-ubuntu-16-04-alongside-with-windows-10-or-8-in-dual-boot/
I came across some problems, since I installed Ubuntu in legacy mode, but it needed to be in UEFI mode... As can be seen in the link above, it told me to mess about with my disk space management and I'm afraid I did something irreversible. Any solutions on how I can delete my legacy ubuntu (without getting rid of windows 10 of course)? Precise detailed steps will be necessary as I'm new to operating systems and linux.
Also, I have difficulty booting the legacy ubuntu recently (finishes booting very rarely). Windows 10 still works fine.
