Windows 8 is not supported in Boot Camp. To get back to a supported configuration, boot from your installation disc and partition the internal drive with the default choices (wiping all data on the drive.) Then restore the OS X startup volume from the last Time Machine snapshot or other backup you made before trying to upgrade. You should then be able to upgrade to 10.8. If you wish, run Boot Camp Assistant and create a Windows 7 (not 8) installation.

If you haven't already done that, it may be too late. I suggest you ask your question in the Boot Camp forum on this site.
