Thank you so very much for your reply, and so quickly!!! This is why I love Windows Secrets and have for years.

So when I get to that segment in the BIOS I can comfortably just say OK and when I reboot into Windows 10 everything should be good to go? The only difference is that I can then use a properly prepared USB thumb drive to boot my computer, correct? Thanks in advance!!! Chip

Steven,

Don’t hold down the F12 key. Just keep tapping it as you boot until you hear a beep. You should then get the boot menu that will let you select your USB device. Make sure your Dell is bootable from USB (BIOS Setting). I boot all the time from USB keys and HDs w/macrium and all is well on all 4 of my Dell computers (1 Desktop {UEFI Secure Boot Enabled} & 3 Laptops {1 w/UEFI Secure Boot Enabled} ).

HTH :cheers:

Hi! I have a Dell Inspiron 7347 I believe. I too have Macrium Reflect (though the paid version). I can do this just a he says. My question is this: When I go into the BIOS and try to change the Secure Boot to Legacy, it gives me a warning that I may no longer be able to boot my OS (Windows 10). Since the main reason for doing this would be to boot from a USB device (thumb drive), can I change this setting safely and is there any reason too since I can boot to a USB thumb drive via the F12 on reboot method (at least to Macrium Reflect and to Dell Restore Media thumb drives? Thanks in advance!!! I love Windows Secrets and I have been using the paid subscription for some time now.
