I had the fun time of trying to get ubuntu 12.04.2 installed on a new Windows 8 Acer laptop the other day. Even knowing what needed to be done it was a complete exercise in frustration. Since Windows was already installed as UEFI you couldn't set Legacy mode permanently without reinstalling W8 (I'm not sure if Windows 8 will even install without it), and to access the BIOS setting to disable "secure" boot the search-the-forums magic command was to set a bios supervisor passwrd first. @$#%#$%! Oh yeah, and you had to hold the shift key down while pressing poweroff in Windows to get it it actually shut down, instead of just quick wake from hibernation bypassing the BIOS access time-window. I'm afraid that simple dual booting by the general public has been made a thing of the past, in a rather clinical fashion. :-( > But someone wanting to dual boot with a pre-installed win 8 > box will have issues using that (do we really want to give > those people 32bit anyways?). The ubuntu download page for 13.04 specifically states that people with computers with a Windows 8 sticker on it will need to get the 64bit version, although I think that's more to do with their 64bit iso having UEFI support but the 32bit version not. there's nothing wrong with running 32bit+pae software on 64bit hardware unless you want to run with >2gb file support. I think any performance slowdown from the loss of registers will be overwhelmed by the DVD or USB i/o bottleneck anyway, so not a big deal. > The reason Dvds work on a Mac is that they always > boot in Legacy mode as detected by the Mac. which is at least something, but new Macs don't come with DVD drives, so... > Ubuntu still has 32bit because there is still plenty of > older hardware that isn't 64bit.

As for me, I'm still very happy with my 32bit netbook for travelling/taking to conferences, & don't excect to replace it for that role anytime soon.
