VM will not boot after update to Parallels 14

I've been running Parallels for a long time. I had an older version (I can't find now what it was) and everything worked fine.
After doing the 'update' to 14, the VM will not boot. It says there is not OS on the boot drive. I cannot shut down the VM either, so I can't modify any settings.

I changed my permissions on the boot file so everyone had read/write access (along with me as a user and administrators also).
Still will not boot.
help!

 

Hi Lotus54. Please provide the screenshot of the error message along with the virtual machine file size.

 

I posted the error message in my original post.
the size is 34.88GB

I tested another virtual hd- it initially started, but after the 'upgrade' to operate with Parallels 14 it did the same thing.
it appears it *may* be a permissions issue, but I have read & write all all users in the 'info' on the virtual machine.

I can mount the VM and it most certainly still has the OS files on there.

 

that fixed it!
thanks!

 

You are welcome. Nice to know that it works now. Please post again for additional queries.

 

I had this same issue and went through the various recommended steps of modifying access rights and editing the XML file, all to no avail, although I did not try the suggestion above regarding Recovery mode and First Aid. What finally worked for me was to use Parallels Control Center to clone the non-booting VM. The cloned VM booted properly, presumably because the act of copying the original created a new VM that MacOS allowed Parallels to have write access to. I then deleted the original VM. I have been a very happy Parallels user for over 8 years and recommend the product to those I think might have an interest. But I encountered this issue a few months ago when attempting to upgrade Parallels on my work Mac and reverted back to the prior version because the recommended solutions were not working for me. I simply couldn't afford to be without my Windows VM at work for any period of time. So a few months later I decided to upgrade the home Mac to Parallels Desktop 14 and ran into the same issue, finally resolving it as described above. I will make another attempt with the office Mac, knowing that a solution is possible. I state all this as a possible aid to others who experience the 'Hard Disk 1' issue, but also to express my mild disappointment with the Parallels technical team. But having said all that, I still compliment them on a great product.
