The USB stick is not recognized by Windows after the TrueNAS installer writes to it. When Rufus prompts for which write method to use, make sure dd mode is selected.
Rufus iso ok for commercial uses verification#
But if you do not choose DD mode, you are undoing any signature verification that you previously performed and introducing a potential vector into downloading a malicious bootloader for the installer. To write the TrueNAS installer to a USB stick on Windows, plug the USB stick into the system and use a program like Rufus to write the. On the positive side, it allows you to put other files on the USB drive, whereas DD mode makes the USB drive read-only, as it uses the ISO9660 read-only file system.ĭon’t worry about downloading the files, because DD mode does not use them. As the Qubes installer is signed over the whole qubes.iso file, there would be no way to verify the files that are written to the USB drive match what was in qubes.iso.
The files that it is asking to download are part of that process/bootloader. It installs its own bootloader, reformats and partitions the USB drive, then copies files within the qubes.iso file to the USB drive. You want this, because hopefully you’ve already verified the PGP signature of the qubes.iso file, and this will ensure what is written to the disk matches what has been verified. Rufus 3.0 is no longer supported on Windows XP. Rufus requires reformatting the USB drive for each use. Every byte starting from byte 0 of the USB drive will match your qubes.iso file. This tool does not support creating multiboot usb with multiple ISO files, and can not have multiple operating systems on USB unless the ISO file supports it. When selecting DD mode, Rufus is doing a byte-for-byte copy of the qubes.iso file to the USB drive.
You can say yes to download the files if it does not allow you to go further, but those files are not used if you select DD mode.
