I have just created a USB boot disk using the universal USB installer program to create a bootable Ubuntu 12.04 flash drive. I did this in Windows 7 on my laptop. I am going to install Ubuntu 12.04 on a Eee Asus Netbook which already has Ubuntu 10.04. Any attempt to upgrade doesn't work so I am going to just upgrade with my flash drive. Problem is the flash drive will not be detected. When it checks for the USB drive it tells me the USB drive is not detected. When I select the USB drive from the bootable menu (which ironically shows the drive even though the netbook says there is no usb drive detected) I get a line that reads "boot:", which then flashes another piece of text so quickly I cannot read it but goes back to this "boot:" line. It loops forever.
Basically I cannot boot from my USB drive. Perhaps I should just reformat the whole thing but I don't know from where I can do that in Ubuntu (I'm a bit of an Ubuntu noob). Any ideas?
