Hi
before about week, I started topic, because my windows7 installation startup speed was realy slow, lot of you told me that I have to flash bios and my setup will run ok, but it didn't. So I looked for real problem and i found it and it's kind of stupid

Only thing I have to do, was disable Floppy Drive in bios and vola, it's work fine, Installed Windows 7 x64 in 12min 47sec, from putting cd in the drive till logging in window.
