when i attempted to get Ubuntu on my school laptop, i accidentally deleted windows. then because when setting up Ubuntu i set its storage so it would only take up 30 gb i figured the rest of the space was still there so re installed windows hoping it would find the space but no. is there any way i could get my original stuff back cause i need it for school. (no i did not backup, however would it be possible for a friend with the exact same computer to make a backup for me to use)
