When I followed the instruction to install Ubuntu 12.10 with wubi, the come out window ask me to reboot the computer to finish the installation. I followed the instruction and stopped with the message I have left below. Could you please tell me how to finish installation? I'm worried if I follow the instruction below to remove_hiberfile in Windows it would result in a failure to boot my Window 8 system:

Completing the Ubuntu installation.
For more installation boot options, press 'ESC'now...

Busy Box v1.19.3 (Ubuntu 1:1.19.3-7ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs) windows is hibernated, refused to mount. Failed to mount '/dev/sda2/: Operation not permitted the NTFS partition is hibernated. Please resume and shutdown Windows properly, or mount the volume read-only with the 'ro' mount option, or mount the volume read-write with the 'remove_hiberfile' mount option. For example type on the command line:

mount -t ntsfs-3g -0 remove_hiberfile/dev/sda2/isodevice

mount:mounting/dev/sda2 on /isodevice failed: No such device

Could not find the ISO/ubuntu/install/installation.iso
This could also happen if the file system is not clean because of an operating system crash, an interrupted boot process, an improper shutdown, or unplugging of a removable device without first unmounting or ejecting it. To fix this, simply reboot into windows, let it fully start, log in, run 'chkdsk/r', then gracefully shut down and reboot back into Windows. After this you should be able to reboot again and resume the installation.
