Uninstalled Ubuntu, "No such partition on reboot"

Uninstalled Ubuntu, "No such partition on reboot"

I had a dual boot with Ubuntu 13.04+ Windows 8, Windows 8 being the
primary system. I decided I don't need Ubuntu at the moment, so I wanted
to install it. Here are the steps I took.
Used EasyBCD to write Windows onto the MBR
Deleted the Linux partitions, and expanded my C:// drive to take the free
space
After doing these steps, my Windows HDD was back to normal, and I had more
GB as expected. When I tried to reboot, I get the error: no such
partition, with a grub command prompt. I'm assuming this is because the my
computer had grub as the default bootloader set, and since I erased
Ubuntu, it doesn't know what to do. How do I boot back into Windows? I
don't have access to my Windows 8 disk, but I do have a USB key with
Ubuntu 13.04 live boot on it.
Thanks!
