I made a boot USB and stuck it in before I launched my computer.

The Ubuntu screen appeared in black, with options, I chose to install on it on my hard-drive. Everything was fine until it got to the stage when the text on the screen displayed ata1.00: error: {UNC}. Then it showed ata1: EH complete

It repeatedly showing those two messages and it goes on and on nonstop

What can I do?

The original problem was that my Dell Inspiron Mini 10 had Windows 7 installed, crashed and on start-up started showing the message: operating system not found.

Thats when I decided to try Ubuntu and that's what happened.

when restarting with the Live USB, have you try the option "try" instead of "install". Try it now anyway, it may help you discovering the source of the problem. In general, always try before installing. – Boris Jul 17 '12 at 21:49
i agree to try ubuntu. This will run ubuntu from live usb disk. your error is related with hard disk failure. get a new hard disk. – skumara Jul 18 '12 at 2:34
is you can boot your computer from live usb - choose try ubuntu. than open gparted and try to test your hdd and posibily fix. – skumara Jul 18 '12 at 2:35
your original problem (operating system not found.) may be due to failed hdd as well – skumara Jul 18 '12 at 2:36
