None of which will work unless the OP's booted his CD in UEFI mode to start with. That means, if his system is like mine, having the CD inserted before starting, prodding or whatever until the BIOS screen comes up, then picking the optical drive in UEFI mode, then booting that. Then the option to load all files into RAM is not available. Also, grub is a total failure on this box: it just isn't detected. So I use gummiboot instead. It's also far, far easier to manage if you have more than one kernel to choose from, and it saves you having to learn all that baroquery. Frankly, I'm glad to see the back of grub-2. -- Rgds Peter
