¿Como quito este error: No bootable device -- insert boot disk and press any key?

Intente instalar Windows 7 a mi computadora Acer aspire e5-573 series modelo N15Q1 y cuando reinicie la laptop abrió un menú que me mostraba las opciones de abrir Windows 10 o instalacion de windows, yo seleccione la ultima y entré en la bios, como soy inexperto en este tema cambie una opción que decía UEFI o algo por el estilo a "Legacy". Ahora mi computadora prende y muestra una pantalla en la que luego de varios mensajes dice: "No bootable device -- insert boot disk and press any key". Yo intente abrir la bios nuevamente, pero no pude, probé con todas las teclas posibles, hasta saque la batería CMOS por 30 segundos y la volví a insertar, pero todo seguía igual.

I tried to install Windows 7 to my Acer aspire e5-573 series, model N15Q1 computer and when I restarted the laptop it opened a menu that showed me the options to open Windows 10 or windows installation, I selected the last one and entered the bios, as I am inexperienced in this subject change an option that said UEFI or something like that to "Legacy". Now my computer turns on and shows a screen in which after several messages it says: "No bootable device - insert boot disk and press any key". I tried to open the bios again, but I could not, I tried with all the possible keys, until I took out the CMOS battery for 30 seconds and inserted it again, but everything remained the same.

Hi HashtagOne

1) Turn off your computer.

2) Remove any external devices including your USB drive, Bluetooth devices and headsets.

3) Remove your AC adapter cable, hard drives and your battery (if your battery is removable).

4) Press and hold the Power button for 60 seconds and release. Your laptop may boot up and turn off during this time period.

5) Plug your AC adapter and your battery back (if your battery is removable).

6) Press the Power button as normal to turn on your Toshiba laptop.

Now see if your laptop starts without popping up the “No bootable device” error.

1) Make sure your computer is off.
2) Press the Power button to start your computer normally, then keep pressing the F2 key after the flash logo screen appears to open 3) In BIOS, press the arrow keys to go to the Boot tab.4) There you’ll see the boot options available.
