[ubuntu] Toshiba dual boot problem win8 13.04 : Stuck at boot manager error

System; Qosmio x70, 8gb ram, 1 tb hdd, win8 preinstalled. In windows I partitioned 200 gb for ubuntu or other system. Have been following all options related to:http://askubuntu.com/questions/22183...uefi-supported, and now am stuck. I got the files to load to partition, I can see them, on restart I get the option for win8 or ubuntu. selecting ubuntu gives the boot manager error w/ missing or corrupt file: wubildr.mbr, error 0xc0000007B.
Combing this forum for the last 2 days and have yet to discover any solutions to get beyond this, yet. Help! Thanks in advance.
