Failed to install Zorin16 (Gigabyte M/B bug)

Installing Zorin OS
61

Do you have only two ports total or are you saying that you are using only 2 ports due to the error you see in the Original Post (O.P.)?

62

yes due to the error i only can use 3.0 usb and i only have 2 3.0 usb port.

63

In your BIOS settings, do you see a setting for IOMMU?

64

yes i have

65

Is it enabled?

66

yes i do

67

When you boot from USB, does it go straight to the USB port error or does it show the Zorin Grub Menu first?

68

zorin grub first

69

Can you try booting the LiveUSB, then tapping the e key or the tab key at the Grub Menu to bring up the Grub Editor?
You will know it when you see it as a whole lot of text. Search through that text until you see "quiet splash"
When you do, add iommu=soft to it, to make it look just like "quiet splash iommu=soft"
Then exit the editor and try to continue to boot.
