Boot issue with Dell EFI USB device detected.
Boot issue with Dell EFI USB device detected.
I opened my boot settings and found the UEFI options. It lists EFI USB device, network, diagnostics, and setup settings. The secure boot is enabled. When I tried to boot via USB it failed with "EFI USB Device boot failed." Changing the USB format to fat32 might help if that’s the issue.
Consider switching Boot mode:UEFI to another setting such as UEFI and legacy or UEFI and CMOS/CSM. You don’t need to use UEFI if it’s simpler in most situations. Once you’ve tried this, connect your USB to a functioning Windows machine, press the power button, type "partition" and select "create or format hard disk partitions." This opens the Windows partition wizard. Locate the row for your USB—say an 8GB drive—and note its initial entry as 8GB with one active primary partition. After creating the Windows USB, open it and move all contents to a designated folder, like your desktop. Log into your computer via My Computer/ThisPC, right-click the USB drive, choose "Format" and set the allocation size to default. Pick FAT32 and ensure Quick Format is checked so it gets ready immediately. After formatting, restore the files, confirming any labels such as "active" or "primary" are restored correctly.
