I would like to Dual boot my secondary laptop. I want to keep one Linux Distro (Lets take Ubuntu..!) as my daily driver and try out different distros like Linux Mint, Fedora, Manjaro....etc. How can I configure my GRUB for constantly changing secondary distro?? I don't want to keep common /home folder for them; I just want to try out different distros for a week or may be couple of weeks. Please suggest me a good way to do it.
Edit: I am having legacy BIOS in my Laptop.
