I have posted on the ASUS forums as well as on another hardware site, but I have gotten no good responce. Hopefully someone here may know something.

I am having trouble booting a Windows 7 USB on my P5KPL-AM motherboard. I have verified the USB drive by testing it on two other computers. I have also tried two different versions of Windows 7, work on other two computers, but not this one. What happens is once I boot from the USB it loads the Windows files and goes to the background with the mouse pointer present. The menu to select installation type never loads. See image below:

On the other two computers it did load and the installation process worked.

I upgraded my BIOS to 0518 (latest) and installed it using the EZ Flash utility. The computer still does not get past screen 1 I described above. You can see some of my settings below:

For emulation type, only HDD and Auto work, everything else refuses to boot. HDD and Auto, however, just lead to screen 1.

What I have tried:

- FAT32 and NTFS USB, works on both two other computers, but not on this one.
- Create boot USB both with UltraISO program and manually creating boot sector and copying files, works on both two other computers, but not on this one.
- ACPI mode S3 and Auto, no change in results.
- ACPI 2 Enabled, no change in result.
- PnP Aware OS: On/Off, no change in result with either.
- Unplug mouse, no change.

P.S. I don't have a DVD drive or media so that is out of the question.

USB boot from what i have seen has never been 100% - you can try enabling and disabling legacy mode, usb 1/2 modes and updating the bios but at the end of the day its never going to be 100%, hell even network booting has till this day never been 100% unless you have a realtek 8139 card and the boot disk/cd
