BeagleBoard Black not mounting to PC after mishap.

I spoiled my BeagleBoard by formatting its USB storage.

I was to format an sd card and flash a ubuntu image on it. I inserted the card and attached the card reader to my pc. Here I didn’t realize that BeagleBoard black was also connected to usb mass storage.
When I thought I formated the SD card, instead I accidently formatted the beagleBoard.

Now my usb connection no longer works. What can I do now? I donot know what to do now.
Any help would be appreciated.
