If you've recovered your original (Buster?) oldstable to good working/booting order, you may install Bullseye without a bootloader, thus not disrupting Buster booting, and use Buster or rEFInd to boot Bullseye. If in the process of installing Bullseye, you elect not to mount a swap partition that already exists, you will avoid the installer's insistence on formatting swap, which assigns it a new UUID, which breaks fstab on any existing installation that uses that swap partition, as well as bootloader configs that include the UUID of the swap for resume=. I find online upgrades to be easier than all the reconfiguration necessary to reach my happy state starting from a virgin installation. You could clone your Buster to another filesystem(s), correct the duplicate UUIDs and volume labels, adjust fstab to the new location(s), get booting sorted out, then full-upgrade either the original or the clone to Bullseye. If your PC is new enough to include UEFI, consider switching to it. It makes multiboot less problematic, with reduced possibility for a new installation to damage or inhibit booting an existing installation. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
