It is boot looping. I have tried disconnecting and reconnecting the HDD, connecting it to different HDD sata slots, start up repair, running all of the boot rec commands in CMD with start up disc, and also it says when I do a bootrec/scanos it says No Operating System found. It was working fine a week ago. Nothing changed, and this appears to be an issue. We usually just pull the HDD, back up the data, and reinstall the same OS but I wan't a fix rather than a last resort. This client has VERY proprietary software and I would like to actually fix this.
