DELL Latitude 7490 no hard drive available for boot
I needed several tries to install a Windows 10 on an empty DELL Latitude 7490. After giving up with a self created USB stick I bought an installation DVD and lo and behold Windows was installed. Or I thought so. To be able to boot from an external DVD I changed the settings in the BIOS. Now I have the situation, that the laptop boots, when the external DVD with the installation DVD is plugged in, but not when it is plugged out. When I start the Laptop with F12 I get the following menu: Boot mode is set to: LEGACY EXTERNAL DEVICES: Secure Boot:Off Onboard NIC UEFI Boot: **Onboard NIC (IPV4)** O
