Norton Boot Removal Tool iso/flash doesn't work

Posted: 15-Oct-2021 | 11:36AM · 5 Replies ·

Got the NBRT iso download from Norton website by launching Power Erase scan from within 360. Norton help for NBRT has a video showing how to download the .iso file and directing you to a website to download the Rufus utility to create a bootable flash drive from the Norton iso image. Help video shows an older version of Rufus but basically you choose FAT32 for flash file system and MBR and the option to make a bootable flash.

This flash will not boot on 2 different Windows 10 machines. The hp can boot from Retrospect Backup 32 or 64 bit flash drive for disaster recovery and the Dell desktop can only boot from the 64 bit Retrospect flash tool. If the NBRT was made correctly it should at least boot on the HP. Not sure if the nbrt.iso creates a 32 or 64 bit image and Norton tech support is clueless. Norton 360 should be able to create the boot flash tool from within the program, not relying on a third party shareware utility to make this tool.

Any suggestions would be appreciated.

Hello. Are you selecting "Legacy Boot" in  your BIOS to select the correct device to boot from?

If you use a UEFI-enabled computer, select the recovery media under the Legacy Boot option instead of the UEFI Boot option. The recovery media is the Norton Bootable Recovery Tool DVD or USB drive.

Thanks I hadn't seen that particular link yet, I only saw the video on another page.

i'm guessing that the Retrospect Disaster Recovery created USB tools that use Windows ADK and Retrospect from the flash drive must support UEFI as both computers can boot from the 64bit tool but only the Dell can't boot from the 32bit tool.

I'm not sure about the HP bios by on my new Dell 8940, you must disable Secure Boot before you can switch to Legacy boot. You can a long warning about not being able to boot again and I was unsure if I would have a problem switching back to UEFI with Secure boot afterwards. i don't want to brick the new machine not knowing. I don't suspect a virus that needs the tool yet but I want to be prepared just like I had made the Norton Power Erase boot USB tool many version ago. It's too bad Norton couldn't just have a few versions of the .iso image depending on you BIOS.

UEFI is the issue since secure boot will only allow the factory installed OS to post and run. Legacy allows your DVD drive and flash drives as an alternate boot source in the event the main HD becomes unbootable. Caution is indeed in order, especially if, you aren't making and keeping backups on a removable source to recover from. I have disabled secure boot on machines in the past with great success and recovered. Doing so on your part would be totally at your own risk of course.

I just booted the HP (which I have recovered win the past with the Retrospect USB boot flash) into BIOS and switching to Legacy mode is an option but I did not attempt because upon restart a screen came up with a 4 digit code to continue to Legacy. Not being sure if I would have a problem switching back to UEFI. Since I did not have to go into the BIOS for the Retrospect Backup bare metal recovery, the Retrospect USB tool must use UEFI. Therefore the problem must with with Norton BRT.

I checked the new Dell BIOS and it appears since tech support installed the latest firmware update that Legacy Boot option has been removed so the current NBRT would be useless if the boot area of the hard drive had a virus.

Thus far I have been reluctant to point out,  Retrospect USB boot flash is the probable issue. You should NOT be using retrospect to boot the NBRT device. Your aren''t flashing the BIOS, simply changing the boot method. If you are seeing a code prompt appear there is most likely an admin password block on the BIOS itself which is either present because, Microsoft has inserted it via a firmware update OR the manufacturer. If the legacy boot function has been removed. Your best chance of a resolution is contacting HP for an answer.
