I flashed my rom yesterday but now I get the following error when I try to change the startup disk to bootcamp:

The bless tool was unable to set the current boot disk​


The only way I can boot into windows now is if I take out any Hard drives that are formatted for mac os. The Windows SSD still works fine as long as there are no mac drives in the computer, but I would prefer not to have to open up the computer and remove the mac drive every time I want to boot into windows.

It was booting into windows fine before I flashed the rom, and I have flashed the rom a few other times and haven't had this issue. I'm not sure why it's happening this time. I don't think it's the windows HD because it works fine when I take out my mac formatted drives. I am using a 2009 Mac Pro (flashed to 5,1) that has Mojave installed on an nvme drive plugged into a pci slot and windows installed on a SSD.

I think I just resolved the issue. All I had to do was reset the pRAM. No reinstall necessary.
