How can I boot from a USB flash drive with Alienware Aurora R7?
The issue was that I should have used the MBR partition scheme (and not GPT) when creating the bootable USB flash drive with https://rufus.ie. Here are the proper settings:
After doing so, I see USB in the boot options:
I didn't expect the partition scheme was incorrect as on one of my other computers (non Aurora), if the partition scheme is incorrect, I can still see USB flash disk as a boot option:
and I get a clear error message:

How can I boot from a USB flash drive with Alienware Aurora R7?
I have enabled the USB boot support in the BIOS, but I don't see USB in the boot menu.
USB boot support is enabled in the BIOS:
No USB option in the boot menu:
The USB ports are activated:
Switching from legacy to UEFI boot didn't help:
The USB flash drive seems recognized as its light indicator is flashing when the computer starts. The USB flash drive was formatted to be bootable with rufus and has an image on it. It shows up in Windows Explorer when logged into Microsoft Windows:

DrZoo about 5 yearsI’m assuming the USB has been formatted to be bootable and has an image on it? Does it show up in explorer when logged into Windows? -
Franck Dernoncourt about 5 years@DrZoo correct, using rufus.ie

DrZoo about 5 yearsAnd it shows up in explorer?

Franck Dernoncourt about 5 years@DrZoo I'll let you know in around one hour when I try

Franck Dernoncourt about 5 years@DrZoo It shows up in Windows Explorer when logged into Microsoft Windows. I have added a screenshot of it at the end of the question's details. I'll create another bootable USB key on some basic Ubuntu to make sure the issue isn't specific to this USB key. I'll try on Monday or Tuesday and will keep you posted. Other ideas welcome in the meantime!

DrZoo about 5 yearsHmm interesting. I’d try making another one as you suggested. You seem to have everything correct.

Franck Dernoncourt about 5 years@DrZoo It seems that the USB flash drive was formatted for UEFI (screenshot from another computer that isn't Alienware Aurora R7: i.stack.imgur.com/rUFrl.jpg), so it's strange it didn't work when I switched the BIOS to UEFI. I'll try disabling the legacy option ROMs. Plan B is re-creating the USB flash drive with the legacy mode as explained on the screenshot.

Franck Dernoncourt about 5 years@DrZoo Turns out the partition scheme is incorrect, and in the BIOS installed on Aurora does not give any error message about it.
