    Thank you for any help. I am new with Parallels.
    I have a trash can Mac running Mojave I want to keep.
    I installed Parallels 17 and wanted to have BigSur in an external drive.
    First it says it must create a disk image which I allowed. However when I reach the installation it indicates my internal drive's free space as destination and am afraid to go on.
    Will it be installed as a VM inside my internal main drive WITHOUT affecting Mojave and will I be able to move it to the external drive?
    Thank you very much for any kind help!
