PSA: DON'T I repeat DON'T use DD before noon.
You will end up like me and overwrite your primary data drive which you haven't backed up since over a year. This method has a 100% (1/1) success rate and will drastically decrease your will to live.
Also FUCK MONDAYS!

so you did dd if=file.iso of=/dev/sda then

@PerfectAsshole *of /Dev/sdb
Sda is my win10 ssd, sdb is my windows data drive, sdc is my Ubuntu ssd and sdd is the respective HD. And sde was the USB drive I wanted to target.

ouch. exactly why I type echo before any destructive command

atleast you didn't loose anything important since it was windows haha

@PerfectAsshole well the thing is my home automation software was Windows exclusive same for my Steam account and several other things. And I also lost all of my "spam" mail accounts so I can't reset my password for most of my accounts anymore.
Let's hope that the recovery will be successful.
