Create Linux Jail on Linux!
It's not really a 'Jail'. It's supposed to be like "Windows Sandbox". If you are on Win10Home, you can do this in WSL.
I use Linux on my host.
If you can't delete the VM files, delete them using a console in recovery mode.
So, Open Terminal. Then you can run:
cd ~ mkdir jails cd jails mkdir $WHAT_YOU_WANT_TO_CALL_IT pushd $WHAT_YOU_JUST_PUT sudo curl -O http://tinycorelinux.net/5.x/x86_64/archive/5.4/distribution_files/rootfs64.gz sudo gunzip rootfs64.gz sudo cpio -id < rootfs64 sudo rm rootfs64 rootfs64.gz sudo chroot . popd
The lines with Sudo except the Chroot, is to prevent permission errors.
It's pretty simple. Right?
