Re: PXE-E61: Media test failure, check cable und PXE-M0F: Exiting PXE ROM
If you are seeing PXE boot fail message then the boot order may need to be changed to DVD, HDD, USB then PXE.
If the POST hands off to BIOS OS loader and nothing is found to "boot strap" the OS up, then it will cycle thru the options until it gets to a bootable device.
If nothing is found, the last checked device will be shown with an error message indicating no boot device found.
This usually means that the OS loaded to the hard disk drive (if any) has corrupted or missing boot files, even if the data is still there.
EasyBCD has a repair disk option available that works quite well for repairing non-booting systems. If it comes up with errors with the HDD then it is time to replace the drive. Even new drives can fail right at the start so no surprises there.
If you re-install the OS and is solves the problem (on an older drive) then run a SMART diagnostic and see if you need to replace the drive due to errors listed.
