Tips for Ensuring Your Bootable USB Works
Following these tips improves the chances that the bootable USB will work correctly.
Use a Reliable, High-Speed USB Drive
Choose a good-quality flash drive (USB 3.0 or better) from a known brand. A capacity of 16 GB or more is recommended, as newer Windows ISOs are large.
Back Up Data on the USB First
Creating a bootable USB will erase all existing data on the drive. Before proceeding, copy any important files off the USB stick.
Verify the ISO File
Make sure the Windows ISO file you are using is complete and not corrupted. It’s best to get it from Microsoft’s official site.
Try Different Ports if Needed
If the computer does not detect the USB, try plugging it into another port. Many older PCs boot more reliably from USB 2.0 ports. rather than USB 3.0.
Match the Boot Mode
Make sure the mode (UEFI or Legacy/BIOS) you chose in PowerISO matches your PC’s firmware. If a USB created for UEFI doesn’t work on an older BIOS system (or vice versa), recreate it with the alternate boot mode.
Recreate the USB if There Are Errors
If the USB still won’t boot or shows errors, try creating it again. Sometimes the write process can fail; using a different USB stick or USB port can help fix the issue.
