I had a Wubi install to try Ubuntu out, and decided that I want to do a proper install. I uninstalled Wubi, downloaded Ubuntu desktop 12.10 (32-bit) and put it on an 8 GB fat32 USB flash drive (following the instructions on the website and using the Linux USB Installer).
I am using a brand-new Lenovo Thinkpad T430i (running Windows 7). I have manually set the boot order so that USB HDD is first. I bring up the boot menu (F12) and select the USB HDD device, and here's what happens: the blue light on the USB stick flashes, then stops, and the computer remains on a black screen indefinitely (I've waited this out for 10 minutes).
I tried doing the same routine, but with the 64-bit version of 12.10, and still no luck.
I've looked through Google/forums for advice, but can't seem to find a resolution for my problem.
