clarenc3 Posted June 5, 2013 Share Posted June 5, 2013 Morning all,I'm having some serious problems booting into my Win7 install UEFI USB stick. I've been on v1.04, v2.02 and now on svl7's v2.02 mod, all with similar results. On boot, I set: USB Boot: EnabledBoot Mode: UEFIOS Optim.: Win864bit (should load UEFI settings I think). To create my UEFI bootable USB I have tried: Win7 download tool and a UEFI copy of win7,Rufus, selecting UEFI/GPT boot and a UEFI win7 copy,manually creating the efi/boot folder from a BIOS win7 copyI've also played around with changing to legacy then changing to UEFI to "force" a UEFI drive scan, playing with disabling most boot settings in locked mode (e.g. WLAN=off, USB always on=off), and running off minimal internal setup (removing RAM, removing drives, internal keyboard/touchpad, etc). I've also tried all USB jacks.I've had a few successes on which I can boot to the drive and it remains detected over successive boots along with Win8 but when I reconnect the USB, it's no longer detected.On the few successful boots, it hangs after loading the install files. By "hang" I mean CPU fan turns off, no HDD/SSD activity and no USB stick activity.Have I completely lost my mind and missed vital info, or does this board simply not like USB UEFI? Can anyone else please confirm this behaviour? Thanks Quote Link to comment Share on other sites More sharing options...

That's how I installed my Windows 8 Pro x64 and it was perfect. Quote Link to comment Share on other sites More sharing options...

XXBrain Posted August 3, 2013 Share Posted August 3, 2013 Just set Boot mode : legacy supportBoot priority : legacy firstUSB Boot : enabledHey,I have the same problem. Is setting legacy support really the solution. I dont't want to Windows install the comaptible mode. Is Windows building uefi drive drive although legacy support is selected? Otherwise it would be useless. Quote Link to comment Share on other sites More sharing options...

nsan1129 Posted August 29, 2013 Share Posted August 29, 2013 I'm pretty sure you can install in legacy mode then switch to UEFI afterwards and have no problems. Quote Link to comment Share on other sites More sharing options...
HeroSoul4 Posted August 31, 2013 Share Posted August 31, 2013 Hi if you plan to install Linux after then UEFI can be an issue Quote Link to comment Share on other sites More sharing options...
