can't Boot From USB Flash Disk

[samerselo]

I have a computer based on the motherborad GA-P31-DS3L

the problem is it can't boot from USB flash drive but the flash drive itself can boot other computers normally

what is the problem here

Please hit F12 at startup to get to the boot menu, then choose HDD+ and on the next screen choose your USB Stick by name. You should recognize it, if not just pick the one that does not look like your hard drive names.

Some USB Devices will not work for this or Qflash, can you use your USB Stick and it be seen with Qflash? It would appear as a second floppy drive.

I've done boot correctly as you mensioned

the USB Stick I have is

the first is: transcend JV10 16G
the second is: transcend JV60 8G

and either them can boot on many computers but not on mine

Does it show up in Qflash? You do have USB 1.1 and 2.0 enabled in the BIOS correct? And Legacy USB Storage Detect enabled as well right?

Do you have another brand to test with to be sure it is not maybe a computability issue?

[samerselo]

Yes I can See it from QFlash And I also Saved The Bios On It
Yes The Options are Enabled

Yes I have Another type but I'm afraid to connect it to usb port directly bcz it always caus a power surg I'm Always connecting it to the computer using self powerd usb HUB

The USB hub is the issue then. Power surge? What do you mean? Maybe you have some short somewhere?

You should be able to plug it into the rear or front of the board and have ZERO issues.

No Power Surg Porblem is on another old USB Stick that I don't use It's My Flash ( You've asked me that if I have another brand to use for test) I noticed that My Flash brand draw too much power fom the usb port (sorry If I could'nt explain myself weel )

thank you I've Managed to Solve the Problem

I Reinstalled The MBR on the flash more than once

I use USB-FDD to Boot

Ahh, so you got it then? Nice to hear if so.
