Hello, so I have a microSD card I want to boot Zorin OS from and an internal SSD with Windows. Where do I install the bootloader for it?
The Ubiquity installer will place the Zorin OS Bootloader automatically in the EFI partition of the drive.
You do not need to install it manually, unless you are doing something very particular and different...
What speed are you using for the SD card? Might be a tad slow heh..
Siding with @Aravisian - when you get to the install portion, selecting 'Install Alongside Windows' works wonders; no need to really adjust any settings with that option. Just make sure to disable SecureBoot and Fast Startup in Windows beforehand!
