From the thread you provided:
What exactly will the above commands do? The OP states this will allow the Ubuntu Live installer to recognize my drive, and then install the full version. Is this what you would instruct me to do at this point?
I am concerned about the partitions I made (based on what I'm seeing in gparted on live usb) that simply 'disappeared', or more aptly, 'reverted' to the state the harddrive originally was before I began this trip down linux lane. Is my actual Ubuntu 12.04 install still there? Should I repartition and go through the same installation steps I originally did after running the above commands?
My next question is how exactly should I install grub afterwards? I think we have concluded that my original mistake was writing to the same drive windows was in... does that mean I wrote grub to the the OS partition on the sda? Or did i write it to the 'RECOVERY' partition? Where exactly does the 'MBR' sit?
Thanks in advance for any responses, I am trying to learn as much as I can. I will be back at it this afternoon.
Edit: Typos, clarification.
