oh boy, yesterday I decided that I wanted a new os,(elementary os) but to install it I had to shrink the partition with my current os(Ubuntu) one miscalculation involving converting strange numbers of megabytes to gigabytes I broke ubuntu as I found out sadly after booting into it. the way I broke it was I made the partition that had it on there too small. then making things worse Elementary os broke so I had to delete BOTH partitions and install a new os(Q4OS) that worked and since my home folder(along with steam and ksp) was on a separate partition so it was safe. But finally I had a working os.
