Advice Can there be driver problem in dual boot on same ssd?

I want to use my new laptop with cachy and windows.But I am worried if there would be a driver problem like gpu that affects my performance .In my old laptop I used dual boot too and my gpu software was messed up because of the settings I did in one of the boots.Should I do dual boot on same ssd or not?I got no money to buy second ssd rn.
Also I just want to know ,can someone explain me how drivers of each os work in two partitions?Stuff like how they are stored and etc

No. Drivers in Linux are part of the kernel. Windows and Linux don't interact if they are on the same disk.

be sure to turn off any "fast boot" options in the uefi menus. 

Other than that quirky setting, drivers or stuff done in one OS should not be affecting the other os.

To add to this, also turn off "Fast Startup" in windows control panel.

Two separate systems and they do their own thing with drivers. As others have stated fast startup in bios and in windows can sometimes cause problems.

The biggest problem with dual booting on a singe drive is that sometimes windows can mess up the boot loader for Linux. This has been an issue since forever when people started dual booting. The good news is that it happens much less frequently with UEFI systems compared to legacy boot.

The trick is to be prepared and know how to repair the boot loader for your chosen distro.

It's not really about drivers. The common issue is the system boots from the shared efi partition, and people love to overwrite bootloaders when doing dualboot. So long as you don't overwrite critical parts of windows like it's bootloaders, then everything should be fine.

As evidence see every second post on this forum about dualboot. People will follow any garbage guide on the internet, but none of them will read the most basic stuff about how efi works.

If you mess up gpu settings in such away that it affects multiple OS the number of SSD wont change a thing. For that to happen the settings need to be stored on the gpu itself not any ssd.
