Reflect Rescue Media USB Not Booting

Made Reflect (free) USB rescue Media as per the instructions. Process finished successfully. USB plugged into a USB slot on the back of the machine.

My computer MoBo Asus M4A88T-M (purchased 2011), non UEFI. BIOS set to "removable media" 1st choice boot and HDD 2nd choice. This MoBo has splash screen startup selection "F8 Boot Menu". Selecting F8 shows option of booting from the Reflect USB.
Selected the Reflect USB. Next screen shows; "Remove Disk or other Media" and "Press any key to restart" Did not remove anything, pressed a key and machine reboots into my win 10 HDD.

Questions;
1-why will the reflect USB not boot to the rescue media?
2-why would i remove anything?
3-do I really need the Reflect rescue USB?

Thanks
Tom

added edit - I have Reflect ver 7.1.2646 and I have made a new image of disk on an external HDD

In the BIOS, there's should be BOOT priority and BOOT order. Did you set both to point to the Removable & Reflect USB ?
In addition, rebuild the Rescue disk, make sure you uncheck the option pointed by the arrow in the screen shot:


Rescue disk is needed to restore the backup image when needed.

Yes Bios is set to boot 1st from USB. Yes on selecting F8 and getting boot menu USB was selected.
The box and option you indicate in your pic is graded out unable to select.

Open Disk Management & Double check if the USB is formatted with FAT32 and set to "Active".

muchomurka, thanks for posting that -- I'm going to use it on all my future USBs, whether MR or something else, regarding making USB boot sticks.

For both yes

Hi chideock, your problem is well-known issue of Reflect. Use this procedure to prepare USB dongle BEFORE creating rescue disk:
Preparing a USB stick for Windows PE - KnowledgeBase v7 - Macrium Reflect Knowledgebase - KnowledgeBase v7 - Macrium Reflect Knowledgebase

Perfect. Works and shows the V7 Macrium and WinPE 10. Also it found the Macrium image that I have saved on another external HDD.
I now have a working rescue USB for Macrium.

Thank you.

Yep, this is the same problem that I helped another member last week with his LEXAR USB stick:

FYI, I don't boot the Rescue disk from a USB. Set it up on the external/internal disk along with the backup image. It's faster to boot from HD and always available:
