You supposed to install GRUB in a disk, not in a partition. So,
/dev/sda, not /dev/sda1. You select /dev/sda during installation.

I am not surprised here, if you really installed GRUB in a partition.
Computer is trying to boot from /dev/sda, and GRUB is not there, its
somewhere further down in the disk on sda1 partition. I don't think BIOS
is looking for it there.

You can change boot priority by pressing button (usually F9), or
entering BIOS and selecting drive you want to boot from.

But in current state, most likely you will not be able to boot to new
Bullseye on /dev/sda, because GRUB is not correctly installed.
