The PureOS installation iso file contains software that will replace an existing Windows installation with a PureOS installation. If a DVD drive is not available, then there is another option involving Windows.

So the obvious solution would be to burn the iso to a DVD and boot from the DVD drive to install PureOS. Well, Mac users know you can not BIOS boot from the USB. After BIOS booting a PureOS install in VirtualBox, I was able to examine the ISO file and could not find any EFI files needed for EFI booting. When I tried the EFI boot method, the firmware could not detect any EFI files to boot from. Using the BIOS boot method, I was able to successfully install and boot using either a Master Boot Record (MBR) table scheme or a GUID Partition Table (GPT) scheme. I created a virtual machine using VirtualBox and tried both BIOS and EFI boot methods. The iso file only contains the software to BIOS boot.

Note: This is from a comment added by the OP (who does have a working DVD drive): I've since successfully replaced OS X with PureOS from the DVD iso, installed with LVM full disk encryption, and grabbed the linux package firmware-brcm80211, which has enabled WiFi :) If anyone has any tips, please share and help me out – I'd love to get this working! Thanks in advance. I'm thinking that the PureOS ISO isn't (U)EFI compatible, so my older Mac hasn't been able to pick it up on boot? PureOS ISO: $ fdisk ĭisk: geometry: 686/64/63 I also ran fdisk on the ISOs to compare with the Debian ISO (may or may not be useful)… I know that PureOS is a derivative of Debian, so this has left me somewhat confused. Just for comparison, I downloaded the Debian 9 live install ISO ( debian-9.3.0-amd64-netinst.iso), and performed the same flashing process as listed above, and my older Mac successfully picked it up on boot. I expected to see an external media icon labelled EFI.

Inserted the USB into my older Mac (detailed above) whilst it was off, then turned it on (with the Option key pressed), no PureOS boot option was available.

Flashed the ISO onto a 4GB USB using Etcher (on another Mac of mine).

Downloaded from and checked the hash.

PureOS doesn't appear in the boot 'drive' choices when I restart my Mac, so I can't boot from the ISO and run the installer.
