windows 8 usb support

After having installed windows 8 on my satellite p775, everything works flawlessly except for: I cannot get the computer to boot from a usb stick. I can format the stick with windows 8 on the laptop. I can load the program on the stick, but when i try to reboot to let the usb take over, the laptop bypasses the usb and loads windows...any ideas??

In order for a USB flash drive to be bootable, it must have a primary partition marked active. You can use the diskpart command to create it.

1. Be sure you've selected the flash drive before you type clean. It removes everything.

 

2. Be sure to format for NTFS (instead of FAT32) if any files will exceed 4 GB.

I believe you also have to disable fast boot.

Yes, make sure Windows 8 shuts down completely. The normal shutdown is a sort of hibernate. This works.

 

   Settings > Power > Shift key + Shut down

In addition to assuring a complete shut downh I believe Fast Boot must be disabled or it won't look for anything except the hard drive.  I've experienced it.

Yes. I didn't notice this machine probably has a BIOS.

 

I don't believe UEFI has a fast boot. Do you know?
