I am new to Ubuntu and I just got Ubuntu 12.04. but my mouse does not work. After hours of trying to fix it with one of you guys we gave up. He said that the easiest way would be to switch to Ubuntu 13.10 because it had the support.

I put Ubuntu 13.10 on a USB, and when I click the option to erase everything and install Ubuntu it gives me a error message box:

Header: ??? ???

Body text: ??????

I have no idea how this happens. I am running Ubuntu 12.04, but with a trackpad, and it's a pain in the ass. I searched around, but I didn't find anything. Am I missing something?

boot from live usb and click on try ubuntu,is that a desktop screen opened or not? – Avinash Raj Dec 3 '13 at 5:04
  • From the screenshot,it shows that your previously installed ubuntu was mounted,you cant erase a mounted partition and reinstall another version of ubuntu to it.

  • So unmount the ext4 partition through gparted and then try to erase and reinstall ubuntu.

  • To unmount a mounted partition,open gparted then rightclick on that partition you want to unmount and select the unmount option.Your partition will be unmounted successfully.

did you successfully unmounted the partition?If yes then,format that partition through gparted only.After that run the ubuntu installer. – Avinash Raj Dec 3 '13 at 5:35
The partition is unallocated now still giving me the error – Robert Dec 3 '13 at 13:36
create a new ext4 partition for ubuntu through gparted,run the ubuntu installer and then click on the option "something else" and choose the created ext4 partition for installing ubuntu. – Avinash Raj Dec 3 '13 at 14:22
