that after installing Gnu&Linux she will never be able to use Win8 again (or more to the point i wont be able to mess around with Win8 and explore in order to see just how troublesome it is). I get the feeling she would quite happily lose Win8 even if it meant replacing with something better, such as Vista or DVL.

You need to find a distribution that's supporting UEFI boot natively, without disabling it. The one installer I've used (Fedora/Red Hat's anaconda) produces a UEFI installation if the computer booted the install media in UEFI mode; and produces a BIOS installation if the computer booted the install media in BIOS mode.
BIOS uses a completely different method of booting than UEFI. So you can't just switch the UEFI on/off and expect a previously installed system to work, it simply won't. The bootloaders are different, the partition scheme
is different, it's all pretty much different.
One of the design goals of Fedora is to install along side Windows 7/8 UEFI, with a UEFI installation of Fedora. At this point it might be worth trying Fedora 19 beta, so that if you encounter problems you can file a bug and thereby make the distribution better.
