EDIT: It turned out to be some strange issue with the USB key. If anyone else is encountering this I'd recommend using Universal USB Installer instead of Unetbootin to burn the .iso, then, after install, use Boot Repair to get the boot options right and ensure Launch CSM is disabled in Aptio.
Hi, I've been trying to install Ubuntu on my Asus laptop but it's proving extremely difficult to get the bootloader to recognise my liveUSB due to this godawful UEFI thing.
Bit of background: When I bought my laptop I also bought an SSHD and a caddy. My friend very kindly installed the SSHD in the optical drive for me and installed Arch on it. Unfortunately, something went horribly wrong during the install process, and when I tried to get it up and running with a desktop and all the other usual bits and pieces I found that all the libraries needed for internet access and... most other things weren't to be found. Installing them from USB did nothing so after a few weeks of booting back and forth between W8 (to search for and write down terminal code) and Arch (to try typing in said code in the hope something would happen) I gave up and decided to just try installing a distro which has all the required libraries as standard.
Fortunately, my friend had taken care of most of the donkey's work like disabling fast boot in W8 and disabling secure boot in aptio, so I can at least access the boot menu easily enough. I tried first with a UbuntuGNOME 13.10 image. I burned it to the USB with UNetBootin and it all seemed to go OK. It didn't show up as an option on the boot menu so, as per advice on the internet, I enabled Launch CSM. That solved the problem in that the USB key (or something) now shows up as "Generic Storage Device" on the boot menu but when I try to boot from it it gives me an error "Reboot and select proper boot device or insert boot media in selected boot device and press any key."
I tried adding a boot option, but the only drive it'll let me select to do so is the SSHD Arch is installed on. I also tried using WUBI just on the off chance, but it only recognises the drive W8 is installed on... I don't particularly want to overwrite W8, and the whole point is to install it to the SSHD anyway. I tried burning a generic Ubuntu 13.10 image and used that... but exactly the same problem. I'm pretty sure the USB key isn't the issue as I've used it for a bunch of stuff, it was also the installation media for Arch, which went fine apart from not having some libraries.
So yeah... I'm a bit out of options here. My goal is to set up a dual boot between W8 and UbuntuGNOME, which I'm pretty sure I can do, but not unless I can get the bootloader to recognise the liveUSB. The whole thing is a bit worrying because I used to have no problem installing a new distro using BIOS, but with this whole UEFI thing it's turning into a bit of a nightmare. I'm pretty sure anyone not used to mucking around with their computer like this would have given up long before now.
