My computer no longer boots Windows or the installed operating system. Instead, I may get this error:
PXE-E61: Media test failure, check cable -or- Check cable connection! PXE-M0F: Exiting PXE ROM.
and/or one of the following messages or similar:
Operating System not found No boot device available- No bootable devices--strike F1 to retry boot, F2 for setup utility No bootable device -- insert boot disk and press any key No Boot Device Found. Press any key to reboot the machine Default Boot Device Missing or Boot Failed Reboot and Select proper Boot device or Insert Boot Media in selected Boot device
What does this mean and what can I do?
This question comes up often and the answers are usually the same. This post is meant to provide a definitive, canonical answer for this problem. Feel free to edit the answer to add additional details.

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.
This error usually indicates a disk failure, but be sure the disk is properly attached to the system
This usually happens when the computer cannot find or communicate with the hard drive or SSD where the operating system is installed. In most cases, this indicates that the drive has failed.
Many computers are configured by default to fall back to PXE boot in the event it cannot find a drive to boot from. The idea is that if there is no hard drive with an OS installed on the computer, then the computer may be a thin client and should try to boot from the network. Except in certain business environments, there is generally no PXE server to load the operating system from, so it fails with an error.
A failed hard drive typically will not communicate with the computer, causing it to disappear from the system. Repetitive buzzing, clicking, or beeping noises are a common indication of a hard drive failure. SSDs contain no moving parts and do not make noise during operation, so you may need to enter the UEFI or BIOS setup to determine if the system detects it or if the drive has failed. See also: How do I recover lost/inaccessible data from my storage device?
This error can also occur, perhaps intermittently, if the disk is physically disconnected or poorly connected to the computer. This is probably the case if it’s apparent that the drive isn’t doing anything at all. Check that all cables are properly seated and reconnect them as necessary. Also, replace any damaged cables and try using other ports or cables if available.
Less commonly, an erroneous or corrupted boot configuration can cause this error
If you just installed a new operating system or have changed the OS boot configuration, and the hard drive or SSD is operating properly, you may still get this error message, but possibly preceded by a “No active partition” error.
On UEFI systems, this can happen if there is no EFI System Partition (ESP). UEFI firmware executes the bootloader from this partition to boot the operating system, so the system will not be able to boot if there is no ESP. You’ll probably need to repartition the disk and reinstall the OS to fix the problem. It’s also possible that the OS doesn’t properly support UEFI boot; try enabling BIOS compatibility mode and see if it works.
If an ESP is, in fact, present and you get this error, this typically means that the bootloader it contains is missing or corrupt. A procedure to repair the EFI bootloader on Windows systems can be found on the Dell support website and in this answer. A summary of the steps follows:
- Boot to a Windows installation or recovery disk
- Click Repair your computer and open Command Prompt
- Use DiskPart to assign a drive letter to the ESP
- Navigate to the directory on the ESP where the bootloader should be stored (
<ESP drive letter>:\EFI\Microsoft\Boot\) and run
- Back up or remove the old BCD, then rebuild it:
bcdboot c:\Windows /l en-us /s <boot letter>: All(where
<boot letter>is the drive letter of the boot volume; add
If your system uses legacy BIOS firmware or is in BIOS compatibility mode (formally known as the Compatibility Support Module or CSM), this means that none of the partitions on the disk have been set as active. The BIOS can only boot from an active partition. You’ll need to boot into a Linux live disc or other environment and change the settings to set an active partition; this can easily be done with most partitioning tools.
Parts of this answer were taken from a previous answer.
Note: Use and implement solution 1 because this method fully tested our system.
