Hi :)
Thanks :)  Err with normal Bios and Mbr it is supposedly possible to copy the Mbr using dd or dd-rescue or something, in order to restore it if things go wrong.  Is that possible with Uefi?  Do you happen to know the right addresses to copy? 
Regards from
Tom :)

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.
