GRUB not opening on startup, dual boot Windows 10/Manjaro

ah okay, live and learn. I’ve already wiped both drives. Do I need to do anything this time round to get it going?

oh no haha … yes convert the mbr drive to gpt and then you can proceed with install

do you mean convert it from bios? This is on a fresh emtpy machine

no boot into live usb of manjaro, open the default disk app, and create a new file system on the mbr disk, then install manjaro, then install windows on the other, now gpt disk and thats it
