Why I'm having a problem with linux kernel when dual boot with windows?
 
So my problem is when I dual boot linux and windows I face overheating when I start linux and I face desktop environment glitches and laggs.
At first I thought it was because if the distribution I use,so I swithced from ubuntu to linux mint and I faced the same issue then I switched to deepin os,but before that I bought ssd and I put it beside my hdd in the same laptop and I installed windows on the ssd and I installed deepin os on hdd, and here is what I've noticed:
when I reject the ssd from my laptop and run linux on the hdd it runs smothly without any error, but when I insert the ssd in the laptop and run linux from hdd problems started I don't know why,so I checked my system monitor and I noticed that a process called kworker start to overload on the cpu,that's why my laptop overheat,the same problem happened when I the 2 systems were on the same hard drive.
so to summarise,kworker overload when windows is detected,kworker works fine then there's no windows detected,and the desktop environment too as well whether it's gnome or cinnamon or kwin.
I searched for kworker and it has something to do with the kernel and with procesing.
Anybody knows why that happens?
PS:I have hp laptop with intel core i7-4500u cpu, nvidia geforce 820m gpu

Boot with splash and/or quiet disabled.
Can you see relevant error messages?

Boot into recovery and issue
Code:

journalctl
Can you see relevant error messages?

Well, even given the old rivalry between Microsoft and Linux, I doubt your computer overheats because it finds Windows somewhere. It may be related to the additional disk, though.

It's not quite clear what you want to tell us. How does the problem relate to the desktop environment?

In addition to ondoho's suggestions, you could check if there are any messages in the kernel's message buffer. You can dump it out with the dmesg command.

There are quite a few results when searching for kworker high cpu. Perhaps one of them fits your situation?
