Installing Win 7 UEFI on a Windows 8 Computer

So I recently purchased a Lenovo y480, along with a new hard drive to replace the rather slow 5400 rpm stock drive it came with (the new drive is a 7200 rpm Seagate if that is relevant). I wasn't a big fan of the time I spent playing around with windows 8, so I figured when I got the new drive I'd just put Windows 7 on there, along with Ubuntu 12.04.

I can get Win 7 to install fine in legacy mode, but I can't get it to work when installing in UEFI. Specifically, my install hangs at the "Starting Windows" screen. Here were the steps I went through to try and get it working on UEFI mode:


1) I enabled only UEFI mode
2) I disabled secure boot
3) I used the guide here:UEFI Bootable USB Flash Drive - Create in Windows to make a UEFI bootable USB drive. I used an .iso for Win7 /w SP1, and it installed fine while in legacy mode.
4) When booting from the USB, I go through a couple screens of "windows is loading files". When I get to the "Starting Windows" splash screen, it freezes up. This has happened several times, I allowed it to set there for a few hours as well just to make sure it wasn't trying to load up anything in the background.

I've tried a bunch of different tests (changing SATA from ASCI to compatibility, swapping out ram, disabling the wireless,optical drive,etc), but I still freeze on the "Starting Windows Screen". I was able to install Ubuntu just fine with UEFI enabled, it's just windows 7 that is causing the problems. This freezing on the windows splash screen seems to be a very common problem for installing UEFI from the quick searches I did, but no one on the web has posted a solution other than "Just use legacy mode".


As an aside, just how exactly are you supposed to reinstall windows 8 to a new hard drive? I could not burn recovery discs of any kind for windows 8, and the laptop didn't come with any. The only non-torrented .iso files for win8 require a product key, which is of course hidden in the bios and not accessible. OneKey recovery from Lenovo won't allow you to create backup discs either, and the image that it makes of the recovery partition (to potentially put on a usb? This option also was not available to me...) was nearly 30gb, which wont fit on any of the usb thumb drives I have. In the off chance that I actually wanted to try windows 8, how exactly do I get myself an install disc? Lenovo can potentially provide them but they aren't cheap, and it seems ridiculous to pay for something that should have come with the computer in the first place.

1) Downgrade to Windows 7.
Downgrade Windows 8 to Windows 7
Warning you must have the uEFI/BIOS firmware setting in Step Three set.

2) If Using a USB Pendrive on a PC with a uEFI BIOS.
USB Pendrive need to be formated to FAT32 as in
UEFI Bootable USB Flash Drive - Create in Windows
Take note of Step 11 for Windows 7.
Also you will need to use a USB 2.0 port, as there no USB 3.0 drivers in Windows 7.

If you have Windows 8 Pro Pre-install, call Lenovo & order the downgrade rights DVD.

I believe he was using the USB 2.0 port . If he wasn't he wouldn't be able to boot from it if he was using USB 3.0. He would have to slipstream the driver of USB 3.0 to his Windows 7 installation Flash Drive .



Yes, unfortunately using that link I get stuck on Step 5, because I never make it to the language select screen. After I boot from the USB, it loads some files and then freezes on the Windows splash screen, prior to making it to the language select.

Try using another USB 2.0 port

Unfortunately I only have the one 2.0 port, the rest are all 3.0. I've tried a couple of different flash drives and .ISOs as well.

Yeah, my BIOS is set such that UEFI is enabled, but secure boot is disabled. I made sure to do step 11 when creating the USB install drive. I booted the USB in UEFI mode, and am using the USB 2.0 port, and both .ISOs I tried are win7x64 SP1. It successfully loads the windows files, but freezes on the "Starting Windows" splash screen, before it loads the language settings.

If all else fails, what always works for everyone who's tried it is to Bypass UEFI to Install WIn7

I was able to install win7 in legacy mode, I just wanted to see if I could get it working with UEFI.

Mrhayden,

In BIOS now a days UEFI what is your HD set as? AHCI ? . You might want to boot up into safe mode and see what driver it hangs at.
