After experiencing these problems Why is my desktop background blank after upgrade to 13.04?, Unity isn't working after running `unity --replace` I realised my best bet would be to uninstall ubuntu and reinstall from scratch. So I logged out of ubuntu (after backing up the files I needed, of course) and into my Windows 7 OS and removed the partition on which Ubuntu had been and downloaded the 13.04 iso file for 32 bit operating systems like the one I had previously burned it to a disk and then I rebooted but when I rebooted I received a grub error, "Error: Unknown File System" and the next line had "grub rescue>". Please help me I have NO idea of where to go from here.
I tried typing, 'F12' to boot from my liveCD instead of my harddrive but this resulted in the same grub rescue screen. I also tried taking the CD out of the drive to see if it would do anything and it didn't.
I know next to zilch when it comes to programming so please just tell me, step-by-step, what I need to do.
I am using a Dell Vostro 3500 laptop with 4x3.7GHz processors and 4GB (I think) RAM.
