UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with

MrCrowling88 said:

Hi Guys,

I'm trying to install Windows 7 Ultimate x64 on a Toshiba laptop with Windows 8 pre-installed. I'm getting to the boot menu, choose to boot from DVD, press any button to start the installation. It's copying the installation files and then The Windows Logo shows up stating "Windows is starting" and that's where it stops. It doesn't move any further. Would you know why ? Does it have anything to do with the new UEFI boot mode ?

Your help will be much appreciated.

Many thanks,

You'll also need to turn off Secure Boot on the new Win8 PC's: Secure Boot - Enable or Disable in UEFI

If all else fails, what always seems to work is to Bypass UEFI to Install WIn7

I get the same problem. See the attached photo. Secure Boot has been disabled. I AM able to install Windows 7 successfully onto this pre-installed Windows 8 laptop using the legacy BIOS mode, however. Any ideas what I can do other than re-install using the legacy BIOS?

Are you booting the DVD in uEFI mode?

The USB stick, yes.

Also, how do I get to the one-time boot menu on this laptop? I've tried all the F keys and the escape key. The people at Sony are clueless, as is expected. I can press the assist key from shut-down, and then press F11 to use boot from media option, but that still isn't the normal one-time boot menu. In theog's one-time boot menu, it shows a UEFI DVD drive and a P1 DVD drive. I';d like to see if I get those two choices for my USB stick, but since I cannot access the one-time boot menu, I can't check it out.

On many Sony's it is F2.

If that doesn't work then set the device first to boot in BIOS setup.

Thanks, Greg. F2 didn't work, so I changed the USB stick to boot first in BIOS. I still get the frozen screen during "Starting Windows." I guess I'll have to install Windows 7 under the legacy BIOS.

There are special steps for UEFI Bootable USB Flash Drive - Create in Windows

Make sure the stick is bootable on other hardware, that it works. If in doubt what always works for me is using the latest official ISO and UltraISO Software To Create Bootable USB Flash Drive.

Clean Reinstall - Factory OEM Windows 7

Take note of step 11.

I followed step 11 exactly, but it still didn't work.
