Last night I tried to upgrade an Acer Aspire One that my granddaughter uses to Ubuntu 12.0.4 but it failed before it finished and now the machine won't start at all. I've had a look at how to create a bootable USB but the instructions don't seem to cater for cross platform situations.
I have a Macbook running Snow Leopard and I want to create a bootable USB that will allow me to restore the Acer Aspire One to a working state running Ubuntu 12.0.4.
Any advice would be much appreciated.
