There is a laptop acer aspire e5-574g-53hw. I installed ssd in place of hdd, and put hdd into the adapter and installed it instead of a dvd drive. There is Windows and files on the hdd. The ssd is ubuntu. It loads, works, hdd, its folders and files are available in it. But this hdd is not visible in the BIOS, as a result I can’t boot from it in order to load Windows. On the F12 button at boot, there is only ssd to choose from and that's it. Bios updated to the latest. And here is the main question: how to start downloading from the hdd, which is in the pocket of the dvd drive?

You need to add a new NVRAM variable of type BootOption to UEFI, which will be the path to the drive in the ODD pocket. By default, of course, the BIOS does not expect a hard drive to be installed instead of a drive, so there is no such path in BootOptions initially.
If you have Windows installed in UEFI mode, try the following software:

Editing NVRAM is also possible manually, but it's very easy to break everything to hell
