Hi all, just got my G55VW and am loving it! Yes you can bypass the UEFI in the bios by enabling "Launch CSM". You can also install several distro's of Linux with GPT partitioned disc's. (So I've heard) I have just completed setting up my new lappy with just Linux. (Debian netinst) I'm also pleased with the Nvidia 319.12 beta driver.
I got to this point through a very rough 24 hour stretch which seriously frayed my nerves by the time I was successfully booted in and everything worked. I'm a "tester" for the 'VSIDO GNU/Linux distro', (vsido.org) and I have yet to try to get it installed. Taking a break for some sleep first!!
Mine came pre-loaded with Windows 8 which lasted about an hour. What a crappy OS. MS's worst to date IMO. Wiped the disc's, re-partitioned and haven't looked back!
Switching to the older "Legacy" BIOS is a breeze though, truly. When the lappy is getting ready to post, hit the Delete key and once in the BIOS, arrow over to the "Boot" section and at the top of that screen you'll see where it says "Launch CSM". Enable that, and I would advise to 'disable' the "Fast Boot" option that is right next to it. It makes it easier to hit the 'Delete' key in time to get into the BIOS!
G55VW-DH71, 16Gb RAM, 240Gb SSD, Running VSIDO Linux with full functionality! Incredible!
3+ years running this Linux Distro, couldn't be happier!
