Upon initial reboot on my Windows 10 64bit Home installation, the virtual disk goes into a reboot loop after repeatedly displaying a "system thread exception not handled" error message along with a QR code. After several reboots, the VM freezes on the Windows 10 logo. I am installing from a Microsoft USB device on an iMac 5K. Any help would be greatly appreciated.
Hi RobertP7, please check out this article to know that how to install Windows 10 with Microsoft USB installation stick. We would recommend you to download Windows 10.iso from this link and install as suggested in this article. If you want to continue with the existing corrupted VM, there is any problem with drivers on your virtual hard disk. It could cause the System Thread Exception Not Handled error. If you still able to access into your Windows virtual machine (it's boot into Windows OS normally, after the BSOD occurred), you can go to "Device Manager" to check and find error / corrupted drivers. When the error driver is detected, let's uninstall it and reinstall Parallels Tools to get a new one.
