How to boot from usb?

[amir786_z]

Hi there guys I have Asus G750JS with Windows 8.1. With GPT UEFI. I have created multi boot iso with xboot. How should I create bootable usb that will work with my system. Also tell me if I need to enable/disable fast boot or csm. Thanks

You can use rufus to create a bootable usb stick that will work with uefi.
Yes turn off fast boot to gove your bios the chance to detect the usb.

As the message says,you will have to use a uefi dvd/iso as the source.
If you want to modify your own iso or manualy make a usb check this out.

Didnt work. The thing i now understand is that i need a ISO that is GPT UEFI supported. Any tool that create GPT/UEFI supported multi boot ISO?? Xboot creates MBR/Bios supported ISOs only.

The link shows you how to copy the uefi files to your iso from a working windows installation,that is your only chance.

Other than that you will have to find an installation disk online that is allready uefi,if you download 8.1 from microsoft it will be uefi.

New technology also brings new disappointments... I can't find any software that create multi boot GPT/UEFI iso.

I think I have to give up. Tried many times but nothing seems to work. I created macrium rescue usb. Booted from it with no problems. But wanted to create a multi boot usb with all tools in one place.

You can use Xboot and WinToFlash

I created multi boot iso with xboot. But it's not GPT/UEFI supported.
