Resolution


The BSOD happens due to multiple CPUs assigned to the virtual machine.
Please decrease the amount of CPUs down to 1.
To do so:

1. Shut down your virtual machine if it is started now.

2. Click on Parallels Desktop top menu -> Virtual machine -> Configure or on
Configure button on virtual machine panel.

3. Switch to General tab and in "Processors" drop-down list set virtual
machine CPU number to 1.

4. Hit OK to save changes and start the virtual machine. This time it should
boot normally.

5. Login and wait while Parallels Tools are being installed.


After Parallels Tools are installed, it is safe to return the previous CPU
amount.
