During the March update, the Pro hosed. I finally was able to coax it to boot, but it just doesn't run right. So I tried to reset using the PC Settings tool, but it returns the message that I don't have the needed files. The recovery partitions are intact and healthy. Support walked me through a series of command prompts to cure the problem to no avail. I was transferred to Singapore, and it will cost me at least $300 to send the unit back to the States. There must be some way of restoring the unit. Advice?
