I'm a longtime Windows user who's curious to toy around with Zorin OS. I'd like to install it to an external USB HDD and manually select, via my BIOS shortcut, whether to boot from the external HDD. I know I need to use the "Something else" option when choosing the installation type, but could use some direction on how to configure partitions.
Specifically, are there partitions that I need to create in order to install Zorin properly? Or is it simply enough to create an ext4 partition and mount root? I've seen various guides that refer to setting up all sorts of different partitions, including a boot partition and a home partition, and frankly I'm just stumped.
I also need some guidance on where I need to install the boot loader. For now, I don't want anything on my current boot drive changed at all. I want prefer to manually chose to boot into Zorin by pulling up my BIOS boot options upon startup and selecting my external USB HDD. Does that mean I should install the bootloader to my external USB HDD?
Thanks for any assistance you learned Linux experts can provide!
