I am trying to find a solution after applying the dual boot to install in my computer ubuntu. I was redirected to "How can I change/convert a Ubuntu MBR drive to a GPT, and make Ubuntu boot from EFI?" and I the community says that I have to convert the disk.
But, I would like your advice please to know which part of the disk I have to convert? because I would not like to lose my personal documents in the windows drive or do something wrong. Please is there anybody out there to give me and advice?
I put a picture of the result of gparted:
