Unsure on the creator side of things, but besides PeerTube, which uses ActivityPub like Lemmy/Mbin/PieFed, looking at Grayjay’s sources list, there are some others, like Rumble, Odysee, BiliBili (Chinese), Nico Nico (Japanese), Dailymotion and Bitchute. Maybe a start to check?

Been some years since I last used Fedora, so not able to confirm nor deny anything. Sorry for not being able to help further. =/

Dunno what sort of setup you have, but what I would do, considering my setup and by being a tad on the neurotic side, is to unscrew and detatch any drives but the one to be flashed. This, I think, is the only way to be absolutely sure nothing goes in the wrong place.

If you mean different physical drives, I would suggest detatching the drive with the already installed system when installing the second one.

Also, Linux installers may behave differently from one another, so I would suggest testing on another machine if possible, or at least backing up what you cannot afford to lose in the current machine, shrinking the Windows partition with its native partition manager instead, and picking a system whose installer can spot the correct partitions, maybe e.g. Mint with its option to be installed alongside an already installed system, or Endeavour which, from what I remember, can detect empty partitions.

Also if during install, grub is not set up to have both Linux and Windows as start options, there is a grub manager on Linux too, so that can be salvaged.

And lastly, a word of warning, and reiterating a past point, testing something as big as a dual boot in a computer with sensitive and already existing data is playing with fire.

On Mbin instances, it joins 1:1 posts together. Maybe something to ask for the Lemmy engine devs to add?

If anything can be salvaged, I’d suggest backing those up, and then proceeding to make a fully fresh install. That will ensure you don’t come across issues inherited from the previous blunders, and also, I think, will give you the chance to take the same steps, but wiser than before, and so able to avoid the issues you either caused or came across. (Also something I’d recommend maybe around every 1~2 years, precisely because of being able to restart but wiser)
