Hi everyone!
Zorin OS 15.3 is installed on an SSD. I installed a HDD in my PC as a data storage device and formatted it to Ext4 and earlier I've tried formatting it to FAT. When I turn on the PC I go into the bios and select the option to boot from the Zorin OS SSD. After hitting enter, I get a blank screen with a flashing underscore and nothing happens. I get this issue no matter if I format the HDD to FAT or Ext4. When I disconnect the HDD, Zorin OS boots just fine from the SSD.
What am I doing wrong?
Thank you for your help in advance.
