On my MacPro I have multiple Startup drives. On one drive I have 10.11 gm. When I try to boot to this drive the startup gets to the gray screen with the Apple logo and then restarts over and over. It does this in safe mode. All other boot drives boot fine. This is a new HD. I did Disk repair. I reset the PRAM. All seems fine.

The only fix so far is to reinstall the OS. But after a boot or two the problem persists



Any ideas?
