So I just purchased Parallels 11. I used the option to use my existing Boot Camp Partition, which is why I bought Parallels in the first place, because it had that option. Now, it just keeps saying "Upgrading Windows 10 Bootcamp", it gets about halfway then goes to a screen asking if I want to exit and continue to windows, or use system recovery. If I shutdown, or exit and continue to windows, nothing changes. It will just happen again. I've also deleted the virtual machine and tried again, but it just keeps happening.
Hi RyanN1, follow the steps below: 1. Start Windows from native Boot Camp partition on your Mac. 2. Perform SFC scan. 3. Check for Hard Disk errors by running Check Disk. Reboot Mac. Add Boot Camp in Parallels Desktop and check how it goes.
