Hai, I always used unattended windows for several years, I have now a version windows 7 unattended, which can not be installed. Normally when you install you get to the screen where you can choose on which partition you want install W7. But what I get is a screen where I can change language etc. When I press continue, I get a screen with a bar INSTALL. when i click on the INSTALL bar, I am asked for a windows dvd/usb. I have tried several versions unattended w7 versions. Tried 2 usb sticks. I can install Ubuntu so my motherboard is ok. What I have read is the fact that my BIOS is set on AHCI and my HDD is also set on AHCI If I change the setting AHCI to IDE in BIOS, BSOD will appear. I have read many ways to change AHCI to BIOS, non of them do work. I have 1 HDD, 1TB, i7, 16gig Ram. Never had any problem. Normally, USB stick in the laptop, change the boot device and thats it. Never had any problem. Please see the pictures which I see, trying to install w7. Used several windows to usb tools, downloaded the windows twice. Dont know what is wrong. Hope u can help me. dennis
