I got a Lenovo Ideapad Y580 with Windows 8 and I want to install Windows 7 on it.
I followed the instructions on this link to create a UEFI Windows 7 Install USB flash drive - but it does not work.

I followed the steps:

  1. Format my 4 GB USB flash drive to FAT32
  2. Copy the Windows 7 64 SP1 ISO contents to the flash drive
  3. copy /efi/microsoft/boot to /efi/boot
  4. find the bootmgfw.egi in install.wim, copy to the newly copied /efi/boot and rename it to bootx64.efi
  5. restart, enter the boot menu and select USB flash drive in the UEFI boot menu list

But after I select the USB drive and the initial loading windows progress bar finished, it hangs at the "Starting Windows" screen.

Is there something wrong with my steps?

I heard that Windows7 USB/DVD Download Tool format the primary partition on usb to ntfs not fat32, so it may not work with UEFI, is that true? – Ryan Jan 3 '13 at 20:02
Tried the Windows 7 Download Tool. The UEFI mode can not find the device, because Windows 7 Download Tool format the flash drive to NTFS. – Ryan Jan 4 '13 at 2:51
I tried win8 iso with fat32 usb flash drive, it has no problem. But I can not get win7 work through, as I described in this post. – Ryan Jan 4 '13 at 6:00
