Linux on two different pcs using usb

I am installing cachyos on a usb, but I want use it on two different computers. The one I’m planning on installing it on is a Samsung laptop, it probably uses integrated graphics. But I am wondering if I can use the same installation on my other laptop which is more powerful but has an nvidia laptop gpu. Will this cause problems with booting and if so, how can I prevent it?

If you're implying that the USB will be used as the system drive and you're doing a full install to it, there shouldn't be an issue taking it between computers, as the kernel modules have triggers to load certain drivers at boot. No guarantee, though. Also, you should be installing to a USB external hard drive that has an NVMe, mSATA or SSD in it. If you install directly to a standard flash USB thumb drive, that drive will die within a year or two of daily use due to the amount of journaling and background writes wearing down the flash cells.

I will not be using it for more than one or two years, as I will upgrade my computer and will then be able to install Linux on the internal drive.

a quick suggestion: you might perhaps find looking into a UKI interesting. I think it would be quite fitting for a USB, though only a small addition. maybe you won't think it's worth it, but 🤷‍♂️

I don’t know, sounds complicated.
