Toshiba satellite windows 8 downgrade

[lorkus]

I purchased a Toshiba Satellite P855-S5312 over two weeks ago - completely unaware of the issues it has with Quick Books. I have been advised by many to downgrade from Windows 8 to Windows 7 because a full update to make 8 compatible with Quickbooks will not be released until April 2013. Appears that there is some sort of a lock within the machine that will not let me downgrade. Toshiba says it's a Microsoft Problem - Microsoft say it's a Toshiba problem. I've been on the phone with both for more than 15 hours over the past two weeks without any resolution.
Any help would be so very much appreciated.

return it to the store and get one with Win 7

-Shut down Windows 8 while pressing the Shift key to completely power off.
-Power on and press F2 while the Toshiba logo is displayed to enter the UEFI Setup Menu.
-Go to the Security tab and set the "Secure Boot" setting to "Disabled".
-Go to the Advanced tab, enter "System Configuration" and set the Boot Mode to "CSM Boot."
-Press F10 to save and exit.

Now boot to your Win 7 disk and follow the setup instructions

Also, I expect Sysprep expects an MBR disk. So you probably need to use a partitioning tool to remove the GPT partitions. EaseUS has instructions here using its partition manager (free for personal use).
