A new laptop and the screen goes from the DELL logo to CHECKING MEDIA [FAIL] then NO BOOT DEVICE FOUND. PRESS ANY KEY TO REBOOT MACHINE. in BIOS boot options, LEGACY BOOT and UEFI BOOT. UEFI BOOT needs network connection to boot as I understand. With LAN cable plugged in I get: Start PXE over IPv4 Press ESC to EXIT PXE-E18: Server Time Out. I tried using legacy boot but after CLIENT MAC ADDR info displayed the next entry is: PXE-M0F: EXITING PXE ROM. No Boot Device Found. Press Any Key To Reboot Machine. What do I need to check to correct this?
