Hi everyone, welcome! I’m new here and hoping to get some advice. I’m trying to install unRaid in a virtual machine on my Mac to explore it, after being on FreeNAS. I downloaded the installation tool, ran it, and created a bootable USB. Then I started VirtualBox, but it doesn’t recognize the ISO or boot from it. Am I missing something? Should the make bootable process generate an ISO, or is there another step I need to follow in VirtualBox? I’m also considering trying Unraid under the free trial to see if it fits my needs before upgrading my current setup. Thanks! -Jason

The issue arises because ISO files are essentially images of a boot drive, whereas you possess the physical drive. You can generate an ISO from your USB using specific commands. First, ensure your USB is unmounted. Next, locate the drive name in /dev using diskutil list—here it should appear as /dev/disk1. Finally, employ dd to create the ISO: dd if=/dev/disk1 of=./unraid.iso

This process has taken a while, hasn't it? You're doing the right things so far. The USB drive setup and the boot process were correct. The issue with the "access denied" message likely means the system isn't recognizing the boot medium properly. Have you checked the disk image for any errors or corruption? Also, ensure the USB drive is properly formatted and inserted correctly. If you're still stuck, let's troubleshoot further.

It varies based on your USB drive size. The command copies all content, including empty sections, to the ISO file. Are you certain it's attempting to boot from the ISO rather than a virtual hard drive?

Ensure the "live cd/dvd" option is checked. While operating the device, attempt to press f12 to open the boot menu and choose the appropriate storage.
