How to create a Windows 7 system partition manually?

Question

Hard disks

Good afternoon!
There is a laptop with two SSDs Disk0 (Partition0 - system, Partition1 - windows 8, Partition2 - data, everything is encrypted by Bestcrypt) and Disk1 (Partition0 - windows7, Partition1 - Data, not encrypted).
I want to implement switching between systems via F11 (BootMenu).
Tell me how to create a system partition on Disk1 so that windows 7 boots from its bootloader, and not from Disk0 / Partition0?
I can’t disable Disk0 through bios, because it is locked by the manufacturer and allows you to change only the boot priority and system time, but you don’t want to disassemble the laptop.
