windows 7 falls back to vista boot animation

i hope i post this in the right place...
i have the following problem concerning the boot screen animation of windows 7.

i have created a winpe environment using microsoft tutorials and Windows opk. if i normaly copy the files onto a usb flash drive for example everything works as expected and the nice boot animation appears.

if however i use the tutorial to set the stuff up on a normal active partition from a hdd in my computer: decompres the wim and manually set up a the bootloader with bcdedit the old vista ugly annimation comes up, even though i use the exact same files.

if it helps i also remember the old vista animation appearing when i installed windows 7 on a GUI - EFI partitioned harddisk and i was unable to fix it.

as requested i am adding the links to the tutorials which i folowed to the letter:
for image build: http://technet.microsoft.com/en-us/l...33(WS.10).aspx
for creating the boot part (this type has the problem): http://technet.microsoft.com/en-us/l...94(WS.10).aspx
this one works fine: http://technet.microsoft.com/en-us/l...59(WS.10).aspx

any idea would be greatly apreciated.
thanks

How are you booting the boot.wim? A link to the tutorial would also be useful.

Are you by chance using an old version of EasyBCD to boot it?

Bcdedit -store c:\boot\BCD -set <GUID> locale en-US

Obviously use the correct path for the bcd store on your little partition.
