Can I just... run it off the USB? (any downsides?) (lemmy.world)

so I've had problems getting linux to actually setup properly but the functional preview on the boot USB stick itself works without issue, so can I just run it that way, or is that going to limit functionality in some way?

If you want to try to get Linux on the main drive working (since USB works but isn't ideal) there are a few things I encountered.

-some distros just didn't like my hardware. Failed to install, or installed but boot would get errors and halt. The remedy was using an rpm distro rather than deb based (I tried about 10 debs, the rpm ones acknowledged the bios error and moved on)

-secure boot can be a bit of a pain. If you don't want to deal with it, Turnoff secureboot, and in some cases EFI and use legacy BIOS mode.

-if you want Secure boot and EFI. Allow USB boot in BIOS, do the install and ensure it is building a GPT disk with an EFI partition. At the reboot stage it should ask if you want to enroll keys, say yes.

If during reboot it does nothing or boots to windows(assuming you have windows drive). Go into BIOS and choose secure boot option where you can pick which Secure OS it found and move that to top of boot list.

-if it is not those things it is often nvidia on Wayland or X issue on laptops. If you don't want to mess with installing a GPU switcher, you can often set your laptop to discrete graphics before install and bypass the two GPU issues
