I have read most of this thread and do not recall seeing any mention of this, so here it goes.
I have been playing around with Unetbootin for my Asus EEE 701. At the same time, I am also trying to get Ubuntu NR to get going on that EEE.
After wrestling with Unetbootin since late last week, I realized today that it does indeed create a live USB drive for me, I just never get prompted to boot into it. I have to manually hit escape during the POST to select the PCs boot source. Regardless what distro I use with Unetbootin(Ubuntu 8.04, 8.10, 9.04, BT 3). I know it is not the BIOS setup on my laptops(also testing with a sys76 laptop) because when I create a live USB with the previously mentioned Ubuntu NR, it boots up just fine.
Sorry if I lost anyone, but my basic question is this: Why does the Ubuntu Netbook Remix usb stick boot up properly, yet when I use Unetbootin, I have to manually select the boot source?
