I run Parallels 13 on Sierra. HD is a SSD. 95GB are used in Windows. 30GB are free on MacOS. Expandable disk does not expand and switching to fixed size fails with 'not enough space'. I also tried to move the VM to an external HD (2TB) -> Problem still remaining!
Hello @EwaldH , It looks like you do not have enough space on the Windows virtual machine hence please refer the steps provided in the article below to give more hard disk space to Windows virtual machine and check if it works http://kb.parallels.com/113972 . Thanks Alfena
