Similar questions have been asked, but they didn't answer my problem.
I had a partition (Windows & Ubuntu). I deleted Ubuntu and now I am stuck in Grub-Rescue. I attempted to use 1) ls 2) set root 3) set prefix suggested in another question, but it didn't work for me.
I don't care about any of my files or software. I just want to be able to start from zero again. I have two ideas, I just need to know if they would work:
Idea 1: Somehow, delete everything in my hard disk. (How to do this in grub? ) Idea 2: Purchase a replacement hard disk (optiplex 990).
My assumption is that after doing #1 or #2, I would just be able to install Ubuntu from a USB, and this would be relatively easy. Is that correct or not?
I haven't done #1 because I don't know how to "wipe out" the hard disk from grub, if at all possible. I have a ubuntu.iso in my USB, but I don't know how to access it.
I haven't done #2 because I don't know if it will work.
Please tell me what should I do. Any help is really appreciated.
Edit: Could it help me to use a Ubuntu Live CD, instead of a USB? Clarification: I want to have Ubuntu, and I don't have a Windows CD anymore.
