After install nvidia driver stuck on loading initial ramdisk

Check if the ibt=off kernel boot parameter helps: see e.g. here how to do it.
To test it once, before making it persistent with the procedure above, when you are in the grub line that you use, press button E, go to the end of the line starting with linux and add ibt=off at the end of the line (with a space before...), then CTRL+x
