Well a Cd/Dvd is not an option since my lovely daughter decided to demolish my laptop

But I tried to use Startup disk creator and it will reckonize my usb drive but when i browse to the iso and select it simply does not go into the box..I was able to get it on there the very first time but that was before i put in the flash drive.. now it will not do it at all.. Ive tried several restarts and tried alternating gettings the iso before plugging in flashdrive but with no success.
Does anyone have an idea of what I could do.. I simply do not have another computer that I can do this on or I would
