Install windows 7 from usb (prewin7, no csm in bios, secure boot)

[ryanswalters]

I'm trying to install windows 7 from usb, but can't figure it out for some reason? Even if I cant, just like to reinstall windows it came with on the partition? I can't find option for that also. I don't have the launch csm option in bios, or secure boot. This g75vw-ns71 came with windows 7 installed.

Are you using the original ASUS factory partition and just want to erase everything (back-up first if necessary)?
Tap 'F9' as soon as you power on the unit to start the recovery process if this is what you want to do.

By the way if you haven't already, you may want to try to back-up the recovery partition (doesn't save anything else) to DVDs using the ASUS AI Recovery utility although you could also back-up your hard drive image in other ways.

Win7 notebooks will not normally have CSM or secure boot options in the bios, but you may want to keep an eye on the UEFI/non-UEFI boot setting if you have any troubles booting to media.

Yea I agree with cl-albert, your probably trying to install a MBR Version of win 7, your system is UEFI GPT. Also you'll need an ISO that has SP1 built in. Check out Rewben sticky on upgrading guides and notes I think there is a win 7 clean install guide. Pay peculiar attention on setting up a Win 7 sp1 UEFI install media
