Computer cannot boot to Ubuntu 13.04 after installing Netflix-desktop and
later Wine

Can anyone help me with this issue?
Issue: Black screen after boot attempt from GRUB (cannot boot Ubuntu, not
even in failsafe mode) Process to get to Issue: On Ubuntu 13.04, I
installed netflix-desktop following this procedure; Netflix app didn't
show up in Unity dash, so I uninstalled and reinstalled, still to no
avail. Immediately after, I installed Wine, following this procedure.
Since the Netflix app was still nowhere to be found, I uninstalled Wine
and reinstalled it. Nothing... so I restarted Ubuntu, only to find out
that ever since I cannot boot. I've tried several of the options in
Advanced options for Ubuntu on the GRUB menu but nothing.
I have a computer with Windows 8 Pro dual-boot so I'm able to keep
searching for answers online, but I can't seem to use Ubuntu anymore and
will have to resign and reinstall Ubuntu somehow.
Thank you for taking time in looking at my issue.
