I can't enter Bios

My Chuwi ubook had a problem and it asks me to install Windows but when I try to enter Bios it doesn’t let me do anything, it only shows “Chuwi” on the screen and when loading, neither esc nor f2 nor anything like that works.any solution?

You must be more explicit, since in order to help you we need to know what problem you had and what you did to make it now ask you to reinstall Windows. We also need to know your exact model in order to provide you with the specific software and drivers to proceed with the installation. As an information, in order to get to the boot selection menu you must have the Windows bootable pendrive connected and press F7 intermittently (it can be Fn+F7) until the menu appears.
