It will work better if you call Sony Support and order the Windows 8 Recovery DVD's. Then delete all the partions on the hard drive, disable UEFI, format and install Windows 7. I think you will need to do this.

Sony has some machines that are very particular about what OS they will run and what they will not.

So another approach (in addition to getting Windows 8 Recovery DVD's) would be to get Windows 7 Recovery DVD's from Sony Support.

You should be able to install Windows 7 on a GPT disk as long as you have an UEFI BIOS, which obviously you have. But in order to get it to work you need to boot your installation DVD that boots to UEFI mode. For that you shouldn't boot directly to the DVD, but rather start up into your UEFI BIOS and select the boot menu there. It should now have two entries for your DVD drive, one with UEFI (which you should select), and the other without. Your DVD should now boot into UEFI mode and your installation should work. Be aware that this only works when using the 64 bit version of Windows 7.

Make sure UEFI boot type is enabled, could be that is another name for the same option. Not all BIOS are the same.
