Hello all,

I recently built a new computer for a friend, and despite anything I try it won't boot the Windows 7 ultimate installation from a USB drive. This is the same drive I install the OS from for several computers, and I've even tried 3 other drives using the ISO- USB method with Win32 Disk Imager.

BIOS: Z97 Pro4 (P1.30)

Secure Boot is Disabled.
Drives set to AHCI
USB is properly formatted for Boot installation
CSM and Legacy support is enabled and all USB ports have been tried.
I've tried using a single RAM stick in different DIMM slots, but the UEFI is detecting the RAM just fine.
EDIT: Forgot to mention I cleared the CMOS and reflashed the UEFI via USB to be on the safe side. No luck.

The crazy thing is that Ubuntu installed/operates just fine using this method.

System build:
CPU: Core i5 4690k 3.5 ghz
MOBO: Asrock Z97 PRO 4
Ram: Gskill Ripjaws X 2x4GB @ 1600mhz
Storage: Mushkin Chronos 120gb SSD
No optical drive available

USB Sticks:

Kingston Data Traveler 32GB USB3
Verbatim Store-n-go 16GB
(Two pack, used one to successfully install Ubuntu as a test, the others for windows)
Kingston DT101 G2 8GB

Were the other installations upgrades if so there are no usb Drivers are present you need to use the windows7 usb/downloads to create a bootable drive with the drivers on there then as qazzi said point t the bios to the usb drive
