First thing I always do on a new computer is fresh installation of Windows from USB. With Asus N56VJ I had an issue. Everything worked when I used BIOS compatibility mode, but UEFI boot failed.
In order to create USB installation media I used Microsoft’s Windows 7 USB/DVD download tool. Use of that tool results in NTFS on USB. UEFI usually requires FAT32 installation media. Therefore I had to create bootable medium myself as I used to do..
Procedure is actually simple. Just write
DISKPART on start screen and you will be greeted with security prompt after which you will have old-fashioned textual interface. In my case USB was disk 3 (you can deduce it based on size) but your case will probably differ. Double check which disk you are selecting because
DISKPART does destroy data:
DISKPART> LIST DISK Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 476 GB 0 B * Disk 1 Online 931 GB 0 B Disk 2 Online 7168 MB 0 B Disk 3 Online 7648 MB 0 B DISKPART> SELECT DISK 3 Disk 3 is now the selected disk. DISKPART> CLEAN DiskPart succeeded in cleaning the disk. DISKPART> CREATE PARTITION PRIMARY DiskPart succeeded in creating the specified partition. DISKPART> FORMAT FS=FAT32 QUICK 100 percent completed DiskPart successfully formatted the volume. DISKPART> ACTIVE DiskPart marked the current partition as active. DISKPART> EXIT
Assuming that your, newly created and empty, USB drive is under letter
U: and your Windows installation disk is at
W:, you can use
XCOPY to transfer files. Press
XCOPY W:*.* /e /f U:\
After copy finishes, we have a Windows installation USB on our hands. Since Asus stores its Windows key in a BIOS you will have an issue if you want to apply your own Windows key – setup just never asks for it. One solution is to create
U:\sources. It should have following content (with
XXXXX-XXXXX-XXXXX-XXXXX-XXXXX being your key):
Next step is to boot machine while pressing
<F2> to enter BIOS. Since boot is extremely fast, I always need a few attempts to get inside. :)
In BIOS we just select USB disk under
Boot Override on
Save & Exit tab. Once setup starts, proceed as normal. Windows will create GPT disk and all needed partitions itself.
