Unistalling the bitcoin client (which means i have no bitcoin folder inside appdata folder) makes the whole recovery process impossible?
No. But the fact you've used that PC for so many years can easily mean that the removed data was also overwritten, hence it has become unrecoverable forever.
I tried hexworkshop and searched for the "magic bytes" but couldnt find anything.
In theory, if the disk was re-partitioned (for example for fresh Win10), there may be areas now used by other partitions, for example, that could have useful data. But I am
not a specialist and I may be wrong (and scammers can pretend to be specialists and give you false hopes in order to try to scam you, so be overly careful and keep your expectations low).

Something more: I've seen in your post history that in 2017 you were interested in an altcoin. Please also make sure you're not mixing up things, since I don't think that the altcoin worth the effort.
About the altcoin, no I?m not mixing up because I remember mining on my dad's pc because I didnt have one for myself until 2011 when I went to university. So the range is 2009 up to sept 2010. I remember I was making few pennies per day so i could be 1/3 btc if i mined in 2010 or maybe 50/100 if i mined in the 2009. But i dont remember anything other than "few pennies per day"
I would like to find someone to explain me how to use the keyhunter.py script since I have no coding knowledge. I did an image disk of the hard drive to avoid more data corruption but then I simply can't make the script work.
What I did was to download python 3, I run cmd in the image disk folder(first question which folder? I have windowsImagebackup>desktop-name>backup2022-07-28 which folder to put the keyhunter in?) installed pyinstaller with "pip install pyinstaller", made keyhunter executable with "pyinstaller --onefile keyhunter.py" then run the script with "python keyhunter.py" and it says syntax error for missing ()
I saw the same issue in the keyhunter github saying you need to use python 2.7.3. I did that but same thing.
