hi, I want to use GPT with UEFI-BIOS , but I am not able to partition disk with Task Sequence, it gives an error. Does anyone knows how to do it? Is it possible using SCCM 2007 Sp2 r2? If it is possible what are the configuration? I checked this: http://technet.microsoft.com/en-us/library/dd744271(WS.10).aspx but it was not helpfull

Can you select GPT on the properties page? It's under 'disk type' pull down menu. Also, take a look at this thread: http://social.technet.microsoft.com/Forums/en-US/mdt/thread/a6679550-a343-463c-9301-1bf9706ad9af/

i have this option, but it gives and error while applying OS: 80070057 disk0 GPT 1) 300mb for bitlocker 2) EFI 300mb 3) MSR 128 not formatted 4) rest OS image

For UEFI support, to my knowledge, you need WinPE 3.1. http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=5188 http://blogs.technet.com/b/gastori/archive/2011/06/04/configure-sccm-after-update-to-winpe-3-1.aspxJason | http://myitforum.com/cs2/blogs/jsandys | Twitter @JasonSandys
