What we need to know before USB/CD boot a VM in VMware?
Why we need to boot a virtual machine from USB or CD on VMware, such as boot Windows 10 or Mac OS X from USB or CD on VMware Workstation?
Virtual machine is an effective solution to improve system performance. By installing or running rarely-used programs on virtual machine but not your host machine, you can release the space the programs occupy while you close the apps or virtual machine. And the most attractive feature of virtual machine is that you can run it as you are using host machine.
For example, you can run iSunshare Windows Password Genius on Windows 10 to reset Windows password in VM Workstation. Firstly make sure whether the third-party Windows password recovery tools really works. And then take it to unlock your computer when it is locked because of incorrect login user or password.
