Have anyone experience with Windows 7 on EFI installation?

[va!n]

I have build a new EFI based PC for my aunt which is based on following components:

- ASUS P8P67 R3.0 Mainboard (EFI BIOS)
- Intel i7 2600 CPU
- Sapphire HD6850 Graphiccard 1 GB
- 8 GB DDR3 @1333 (2x 4 GB)
- Western Digital WD1002FAEX 1TB (SATA3)
- LG GH-22NS DVD-Burner
- Antec - Three Hundred Tower
- BeQuit Power - silver (amazing silent)

The Problem:
---------------
The new system is based on the new EFI bios and i changed all the advanced settings and tried the optimized standard values / settings. Installing Windows 7 x64 works fine but booting windows - without any autostarts - still needs about 60 - 80 seconds from the moment when turning the PC on and this boot time is still to long!!!

My own system with Windows 7 x64 on an ASUS P5Q and Intel Q8200 (sadly no EFI bios) starts in unter 1 minute from the moment when i turn the PC on!

Under windows i see only the 100 MB partition but no EFI partiton! When entering the EFI bios the HDD will be shown as normal HDD, where my 8 GB USB stick will shown now as  8 GB USB EFI - So why does my usb stick is listed with EFI support, while the hdd i want to install windows 7 x64 is not listed with EFI support.

I have no idea what i am doing wrong or if i miss something. Anyone here with experiements to install windows 7 x64 on a EFI based system to boot windows a lot faster? Or any idea how i can get the hdd accepted as EFI supported HDD?

However, tomorrow i will try to contact a pc shop and ask for any idea/help too.

Today i visited and phoned with some "known" computershops about, how the EFI BIOS can accept my HDD as EFI HDI and how Windows7 can feature of this.

I was really amazed that nearly nobody knows what EFI brings... Most ppl just think and say its a normals BIOS with just a new GUI with mouse support and nothing more! So what?

What about all the infos about EFI and that its brings ofcourse a new GUI with mouse support but the most important thing, OS (like Apple, WIndows7) dont need to load drivers for GfxCard and so, becuase EFI is loading this in a special way and this is why booting can speed up extreme.

Only one PC seller had a very smart technical support guy, who knows all about EFI and he told me i have probaly to update the HDD firmware to enable EFI support from BIOS. If there is no firmwware for the HDD; there is another way to do this but its a long and complicated way he cant explain on the phone. However, only one guy was able to help a bit and know the real thing (just all) about EFI, where all the others completely failed!

For me the problem still exist... ^^
