Dell OptiPlex fails to detect USB for OS installation
You're facing an issue where your Windows USB installation isn't recognizing the bootable drive, even after resetting BIOS settings. It sounds like the BIOS might need a clean wipe to ensure proper detection. Checking the BIOS options for a factory reset or a clean install could help. Also, verify that the USB key is correctly formatted and compatible with your system. If the problem persists, consulting Dell support or a trusted forum might provide further guidance.
I'm assuming the storage device is ready and formatted properly. Consider turning off secure boot to test, and depending on your motherboard you may need to press a specific key to open a boot menu showing available devices such as USB. The key differs but often looks like F11, F9, or F2. Check the manual for your machine or motherboard. P.S. Re-flash the USB drive using Rufus or Balena Etcher once more just to confirm it's not the drive itself and use another one if needed.
Check if USB boot is active in the BIOS settings. Verify secure boot status. For legacy systems, confirm the drive wasn’t mistakenly converted to UEFI during flashing.
Even as an older version, it must caution. Honestly, using Rufus would have alerted him.
