Yesterday I messed up installing beryl and had to reinstall windows and then linux. I'm back on Ubuntu but are having a lot of trouble getting back to dual booting windows and linux. What happens is I'm only on Ubuntu right now and not windows but to get on windows I will have to erase all of the data on my hard drive so I can't keep linux and then have to reinstall so I tried installing windows earlier and then linux but when the partitioning menu comes up for ubuntu I only have two options
.Guided use entire hard drive
So I can't partition my hard drive to dual boot linux and windows is there any way I can fix this problem?
