Unable to boot from USB drive Elitbook Revolve 810 G2

HP Recommended
Elitbook Revolve 810 G2
Microsoft Windows 10 (64-bit)

Hello,

Originally I've bought Revolve 810 with Window 8.1 Pro.

Recently I upgraded it to Windows 10 64 bit Pro.

The problem is that I can't boot it from USB drive. Computer recognizes USB drive but when I click F9 and get into boot mode ... it recognizes it as 'usb hard drive' but when I select it ... it does not have any effect and does not boot.

 

Could someone help me to fix the issue? I need to be able to boot from USB drive ...

Thanks

Windows 10 64bit with UEFI can only boot from a GPT partition. It may be that your USB boot drive is partitioned as MBR [Master Boot Record] and should be partitioned GPT [GUID Partition Table] for UEFI. 

 

Create bootable USB with UEFI support

Thanks for replying
I believe that my USB is partitioned as MBR
Well. Could you please tell me how to partition it as GPT?
Thanks again
P. S. I am not much familiar with this stuff but in boot selection I did not select UEFI option. I selected to boot from USB hard drive.
Should I select another option?

Use the link in my previous post to install Rufus.

Select your USB Device in the first dropdown menu.

Choose "GPT Partition Scheme for UEFI"

Then browse to and select the bootable .iso file.

You can leave the other selections at 'default'.

Well ... I was able to partition GPT and when I boot I selected to boot from 'External USB Hard Drive' BUT I've got this message:

'Selected boot image did not authenticate'

I found on this forum that it's recommended to 'clear' secure boot option in BIOS. I did it  ... and I'm all set now...

 

thanks so much for the help

I was going to suggest it in my next reply if partitioning in GPT didn't work.

Glad you got it figured out. :generic:
