Cannot get UEFI BIOS to recognise USB drive?

[bruvvamoff]

Hello,

Upgraded all my gear, have no dvd drive to reinstall windows.
Created a bootable windows on external hard drive but my board won't see it on startup.
It's an Asus P8Z68 V LX board.
Is there a setting I need to change for it to recognise USB hard drives?

Then you improperly created the Flash Drive:

There are (2) choices: MBR which is more compatible but if any of the HDD's are 2TB or larger then use GPT.

Preparation MBR:
* Backup data and any registered Apps deauthorize if possible
* Use the latest BIOS and you must use a minimum BIOS version which supports your components.
* Create Bootable Flash Drive MBR USB installer
** Flash Drive -> http://www.youtube.com/watch?v=H4CdEZPTPzk
* Create a folder on Flash Drive e.g. 'RAID' (F6) if needed or 'DRIVERS' extracted drivers

Preparation GPT:
* Backup data and any registered Apps deauthorize if possible
* Use the latest BIOS and you must use a minimum BIOS version which supports your components i.e. 2TB+ HDD(s).
* Create Bootable Flash Drive GPT USB installer
** Flash Drive -> http://www.youtube.com/watch?v=H4CdEZPTPzk
** Windows Installer for GPT -> http://www.youtube.com/watch?v=39qPm1rNnWk
* Create a folder on Flash Drive e.g. 'RAID' (F6) if needed or 'DRIVERS' extracted drivers

Once done boot pressing F8 until the boot manager pops-up, often it will list the Flash Drive twice, more often than not it's the first listed but if failure then the next listing for the Flash Drive.

It turned out to be a BIOS setting. I changed the SATA configuration to IDE and boom, works.
Thanks.
