I recently replaced my broken ASRock motherboard with an Asus P8Z77-V. I am very happy with it except for one thing. It won't boot from my SanDisk Cruzer Glide 32gb flash drive. It does this no matter which program I use to make a bootable usb. The motherboard will boot fine from any other flash drive I use, but not this one. It just sits there with a _.
 


The flash drive itself works fine as storage. I used Fat32 and ntfs to create the drive.(I tried it multiple times using both filesystems)
 
what o.s. are you trying to boot?
which programs did you use?
i've been successful with universal usb installer, hiren's boot cd, and rescue disks from avg, memtest and avast.

you'd need to make sure of these:
enable boot from usb in the bios,
use the native usb 2.0/3.0 ports, not the ones from asmedia chipset,
ensure the usb drive is selected as boot drive,
firmly insert the drive and make sure it shows up in bios.

sometimes 32bit o.s./installers may cause problems, if that happens, try 64bit versions.

for windows installation, sometimes the boot files need "proper" placement if the the tool doesn't place them.
 


I tried to boot both linux and windows from it. I tried universal usb installer, unetbootin, and ubuntu startup disk creator.
 
check my latter edits.

which linux live CD? i've had issues with 32bit ubuntu disks while 64bit ones boot better.
 


Both
 


I have used that before too. Doesn't work. Also, as I said, everything works fine with other flash drives. It's just this one.
