i tried installing ubuntu alongside windows 7

Installing Ubuntu alongside Windows

and i failed so i decided to go with wubi again. after installing it, i noticed a separate hard disk. i investigated and found out that this hard disk is actually for the failed installation.

i don't know where to find it inside the windows system. can anyone please teach me how to remove the 'failed' hard disk.

here's a screenshot

the left side is the current filesystem. the right side on the other hand is the 'failed' harddisk. i verified that it is the failed one because the wubi installation will provide a 'host' folder for the current partition it is currently installed.

i tried looking for the 'failed' one using the windows' commandline but i don't know where to look for the 'failed' disk.

(i used the cmd coz i don't want root.disk to mysteriously disappear again.)
