Please help!

In BIOS SETUP, is it configured for "secure boot" or for "legacy" ?

This limits booting to allow only "trusted" images.

What's on the USB stick?  Linux?  MEMTEST86 ?  Windows 8?  Windows 10?

Can you boot other computers, especially Windows 7 systems, from the USB ?

Secure bootlegacy  i dont think it's enabled because i dont see the menu for it anywhere.

I tried bootling linux with gpt and with mbr partition table in the stick.

I booted 2 computers so far with the same stick both work fine.

Hi,

            create the new USB drive using MBR partition style and try the following bios configuration.

1. Open the bios and enable the boot from USB.
2. Change the boot device order and set USB as the highest priority. (In uppermost location)
3. Disable the HDD boot. (If this option is available in your bios).
4. Disable USB 3.0 from BIOS
5. press esc on boot and select "Change boot device order" [Or simply press f9 on boot].
6. Select your USB drive from the available list.

Good luck.

Hello there,

I have encounter this troulbe as well and all the solution suggested from this thread doesn't help.

I have tried several time with changing bios configuration setting still can not boot from USB (Windows boot USB for installing as well or the USB booth for system maintenance.

Finally, i find out that booting from CD-Room is ok. So let burn the Windows installing ISO to the CD as well as using other Boot CD/DVD instead of USB.

I'm mentioning about the HP Compag DC 7800 desktop computer with 2007 Bios version.

Cheers
