General advice

Additional notes
(Please edit this page to include any of your own useful hints and tips for fixing this error.)
This error usually indicates an unrecognised image format or, less commonly, a corrupted image.
Things to try:
- Check that your build of iPXE supports the type of image you are trying to boot. You can see the list of supported image types in the iPXE start-up banner; for example:
iPXE 1.0.0+ -- Open Source Network Boot Firmware -- http://ipxe.org Features: HTTP iSCSI DNS TFTP AoE VLAN bzImage COMBOOT ELF MBOOT PXE PXEXTshows that bzImage, COMBOOT, ELF, Multiboot, and PXE images are supported in this build of iPXE.
- If you are running a UEFI version of iPXE then only EFI binaries can be loaded. PXE binaries such as pxelinux.0 use legacy BIOS calls and can never work on UEFI.
- If you are trying to load a Linux kernel (or other EFI binary) then you can use iPXE to load it directly; there is no need to load pxelinux.0 first.
- If you are trying to load a Linux kernel, make sure it is build with
CONFIG_EFI_STUBand that it is a working EFI binary. - If you are trying to display a pxelinux menu then you may want to investigate iPXE's native menuing capabilities.
- Check that the image you are trying to boot has not been corrupted in any way.
- The filesize, what iPXE reports during download, and download the same url with browser or other client and check the size.
- If the size is the same it can also be a good idea to compare checksums between original file, file on server, and downloaded file with different client.
- If you are trying to boot an iPXE script, check that the “
#!ipxe” signature is present at the beginning of the script.- If you have edited the script on a Windows machine, check that the script was saved using ASCII (or UTF-8) rather than UTF-16 encoding. (Some editors add what is known as BOM at the beginning which will cause issues)
