How to Fix "Select Proper Boot Device" & "Insert Boot Media"

Are you getting an error that says "Reboot and select proper boot device" or "insert boot media in boot device?" This ominous-sounding error prevents your PC from booting normally, but there's nearly always an easy fix. This wikiHow article teaches you how to troubleshoot insert boot media errors on any Windows PC.

Method 1
Method 1 of 4:

Choose the Right Boot Order

  1. Image titled Insert Boot Media Step 1
    1
    Remove all connected drives and/or CDs/DVDs. Before you do anything else, make sure you don't have a flash or external drive connected to the PC, and remove any CDs or DVDs from your optical drive. Then, restart your PC to see if this resolves the issue.
    • If your PC boots up without removable media connected, it was trying to boot from a drive that didn't contain a bootable operating system. You can avoid this in the future by removing connected/inserted media when rebooting, or by continuing with this method to change the boot order.
    • If your PC still doesn't boot, continue with this method anyway.

    Reboot your PC into the BIOS or UEFI. If your PC is set to boot from external media like a USB flash drive or optical disc before your hard drive, it'll check for a bootable operating system on the removable media at boot time. If it doesn't find an operating system on the removable drive, you'll be prompted to insert boot media.
    • To reboot into the BIOS or UEFI, you'll need to know your PC's setup key. This key is usually F2, F8, Del, Esc, or F10.
    • When you reboot your PC, press the setup key repeatedly as soon as the PC restarts. You may see a message on the PC that says "Press (setup key) to enter SETUP."

    Locate the Boot, Boot Order, or Boot Sequence area. Each BIOS or UEFI is different—you'll need to browse through the menus to find this section. You may find it in a section called Advanced or System Configuration.[1]
    • If your system has a UEFI, you can usually use your mouse to click and select menus and options.
    • If your mouse is unavailable, use your keyboard's arrow keys to navigate, and press Enter to select options.

    Select your hard drive (or preferred boot device) as the first option in the boot order. If you want to boot into the version of Windows or Linux installed on your PC, select the hard drive from the device list. To boot from a removable device like a flash or external drive, choose Removable or similar.
    • If your hard drive is not found, the drive itself might be disconnected from the motherboard. You will need to open your computer and check the cabling. If everything is nice and secure, it's likely your hard drive is dead.
    • The steps to choose a boot order are different in each BIOS. You may have to manually reorder all devices by selecting them and using the arrow keys to move them up or down. Sometimes you'll have to choose 1st and select a device.
    • The device you set as first in the boot order will be the first drive your PC boots from each time you turn it on.
    • If you set a removable drive or CD/DVD as first in the boot order, you can still boot into the operating system installed on your hard drive—just be sure to disconnect the removable media or remove the CD/DVD when rebooting.

    Disable Legacy Mode. Depending on your BIOS or UEFI, you may see an option called Legacy Mode or Legacy Boot. It could be in the Boot Order section, but it may also be in another menu. Browse around for a "Legacy" option, and choose the alternative option, such as UEFI or Secure.
  6. Image titled Insert Boot Media Step 6
    6
    Save your changes and exit. You'll usually need to press F10 or choose Save to save your changes and exist. The specific key you'll need to use usually appears at the bottom of the BIOS screen. Once your changes are saved, your PC will reboot from the selected device.

Run a Startup Repair

    Boot your PC from a Windows installation or recovery disc/drive. As long as you have access to bootable installation or recovery media, you can easily perform additional troubleshooting tasks, including running a startup repair.
    • If you don't have the original Windows DVD or a bootable repair disc, you can create a bootable install drive using any working PC.
    • To boot from a bootable drive or DVD, you'll need to go back into the UEFI or BIOS to make your removable or optical drive first in the boot order.
    • Insert the install or recover media, reboot your PC, and follow any on-screen instructions to boot from the installed media.

    There could be any number of reasons for this. It can really depend on the setup of the machine and the BIOS settings. It could also be that your machine has been set up to not boot from the hard drive anymore, but that's a pretty rare case. More often than not, this happens when the hard drive is physically damaged.
