I have a big problem I have a laptop with dual boot (Windows and Ubuntu) , and two days ago my father made some changes to BIOS (he wanted to change Windows data from BIOS ...) and checked an option that says :
Restore Default... and guess what I could not acces Ubuntu anymore, because my laptop load windows without asking me what system I want to load. Also my father called a fried that came to us to "repair" our laptop and he reinstalled Ubuntu. Now I'm wondering if I can still recover my data, because when I run :
sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
in terminal it shows me a partition called Recovery ( I think all my lost data is there) but I don't know what to do and how to acces it.
Please help me ! I was having in Ubuntu projects and files about web development , I think now they could be lost.
