Hi, I am trying to run an Arch system from Manjaro to try building my system from scratch... I followed all the steps in the wiki and the official readme to bootstrap... setting up chroot, running and unpacking the file in tmp. However, at the last step after populate archlinux, I can't mount the Destination Partition under /mnt because the partition is in use. I can't unmount it either, and can't overwrite the partition because I currently am running one partition (sda1 and sda2 is swap).
Please help!!! I have been struggling with this for endless hours. I feel as if I'm missing something horribly simple, but I'm not sure what.
