Cannot boot from USB for RHCSA remote exam

[bahar]

Hi,

I am trying to burn RHEL exam image in order to test it prior my exam this Friday, however, I am unable to boot up from the USB drive. I am very familiar with changing boot order from BIOS etc.. But I guess the image itself isn't bootable, here are different steps I tried:

• Burn image using Fedora Image Writed => Failed, image is burned but not bootable (tried 2 USBs and 1 external HDD)
• Burn image using dd on RHEL machine => Failed, image is burned but not bootable
• Burn image using Rufus on RHEL machine => Failed, image is burned but not bootalbe
• Creating a VM and use the downloaded ISO image to boot => Failed, unable to boot

I have re-downloaded the image once again in case the first one was damaged somehow, but still no success, if anyone has a suggestion, please let me know.

I am using this link to download the ISO: https://rhdc-static-assets-prod.s3-us-west-2.amazonaws.com/downloads/training-certification/rhrexboo...

EDIT: SecureBoot was enabled, after disabling it, it worked just fine
