Re: How do I switch default bootloader?
You decide which bootloader you want to use, and leave/have that installed. Changing back depends on how the old one was installed. Under the old distro, uninstall its bootloader package, then install again. There may be faster more direct options, but this suggestion is more likely to accomplish this under a wider range of distros and their versions. You then add the boot entries into whichever boot loader you want to use.
