All this Ventoy stick is to do easily again. (From archive.)
There is no need at all, to recover anything.
It is about, how to remove this unbootable, this read-only situation.
I now did try lots of tools and software, until very old Low Level Format (DOS Floppy-Disks) from Western Digital, because SanDisk is from them. Nothing helps.
But now bought a new stick. Did create the Ventoy again.
Then - accidentily - I could see with GParted, that - at least; first - one partition is marked as read-only, with a yellow exclamation mark. And depending on what You do further, for tests, also orange or red; always as sign to see for this read-only status.
And this here, without any boot-error - it is to boot, and further ISOs are to add -, despite this read-only ...
What I really do not need now, is many many explanations to that.
But to me now this just says: oh, Ventoy creates ´some kind´ of read-only.
And my - accidentily - using of (diskpart) bcdboot - accidentily using this parameter - ´/all´, did have this effect to the stick, that it is no more bootable, and this read-only no more to remove, on usual ways.
(The bcdboot command I had to use as last command, to repair boot error from a Win10 installaton, which now works again.
But with now knowing this, I would never use this all parameter or/and plug off just the stick, before running this command.
Or: too said, that this stick has no hardware-switch for write-protection ... )
