Choose a bootloader device that matches your system needs during Ubuntu setup.
You have two SSDs, with one running Windows 10 (256 GB) and the other hosting Ubuntu 20.04 (120 GB). You've already partitioned them, but you're unsure where to place the bootloader.
Choose the disk where Windows is set up (likely /dev/sda), then a boot menu will appear each time you start, letting you pick between Windows and Ubuntu. If you place the boot loader on another drive, you'll need to change boot disks in the BIOS whenever you switch between Windows and Linux.
You should completely disconnect the Windows storage device. Regardless of which option you select, if a bootloader is already present on another partition, the operating system will always install it next. The best way to ensure it appears where you need it is to remove all other drives. Once installed, reconnect the Windows drive, boot into Ubuntu, and execute "sudo update-grub" via Terminal to add Windows to GRUB.
