Not a feature which Microsoft supports.
It's the MS bootmgr display, nothing to do with EasyBCD.
EasyBCD just manipulates the entries which Microsoft displays, it has nothing to do with the generation of the image.
You can use grub4dos as an alternative bootloader http://neosmart.net/forums/attachment.php?attachmentid=825&d=1242354493
which will support custom images.
Thanks Terry60 & JustinW for your replies.
I was hoping that easybcd might have a way to do this. I've been using grub for years to overwrite the xp mbr and get a cool boot splash screen but this time I'm using win 7 and don't feel comfortable doing the same thing. Thought I'd try easybcd to preserve the mbr. Thought there might be something similiar to the tweaklogon screen I use for the windows logon page for the boot splash.
I'll check out the grub for dos although when I click on your link it tells me I don't have permission...google is your friend...
