How can i reset my everything without Reinstalling please??

                                                                     
Currently in my boot directory are the following files:



But Linux Lites Kernel Remover reports:


[size=1.35em]Because the Kernel Remover finds more Linux kernels than I see in /boot, I wonder how and in which directories does the kernel remover search for existing Linux kernels?[/size]

This is no criticism of Linux Lite's Kernel Remover, I only try to deepen my Linux knowledge.

wie und in welchen Verzeichnissen sucht der Kernel-Remover nach vorhandenen Linux-Kerneln? Mir ist aufgefallen, dass der Kernel-Remover mehr Linux-Kernel findet als im /Verzeichnis /boot liegen.

So sieht bei mir derzeit das Verzeichnis /boot aus:




Was der "Kernel Remover" findet:

Hello everybody  ,

I am quite new to linux lite (using linux mint before) and I have a soundproblem with my integrated webcam, don't know if I am in the right place here. I am using guvcview as a software tool. My first attempts to record a video were quite successful, but ever since then, I get an awful noise as a result - as if the camera would now record very directly my computer's fans noise (I hope you get what I mean, I am German...). You can't even listen to the records :-( - sorry, I would not bother you with this if I would not have tried EVERYTHING to solve the problem. Yes, after my two initial records, I did try to improve the sound a little in general on the guvcview board, which may have caused the change?, although I tried to put it back to default afterwards. Does anyone have any idea? - Did I brake my webcam :-(?

Any recommendation will be greatly appreciated
Anais
