 #### For those that just want to get on with using ShredOS, you can download the pre-built .img or .iso images and burn them straight to USB flash drive or CD/DVD. Boot from the USB flash drive or CD/DVD and nwipe will appear ready for you to select your preferred wipe options.

 ## Download the Latest ShredOS .img and .iso files for burning to USB flash drives and CD-R/DVD-R.
 
 NOTE! There may be pre-release versions that are newer than the latest versions listed below, To see all versions, [pre-release & latest](https://github.com/PartialVolume/shredos.x86_64/releases) The latest versions contain a full set of .img & .iso images in 32bit & 64bit while the pre-releases generally only contain a 64bit .img. Which should you use? Well, unless you need either 32 bit images or .iso images I would tend to download the very latest pre-release. Even the pre-releases are subjected to a fair amount of testing before they become a pre-release.

-Note for versions **after** _v2024.11_27_x86-64_0.38_: The .img files for burning to USB flash drives support both BIOS/UEFI booting, as well as saving of generated PDF reports to the USB flash drive. The .iso image also supports both BIOS/UEFI booting, burning to USB flash drives and CD/DVD-ROM, but not (yet) saving of generated PDF reports to the USB flash drive (unless being written in "ISO-Mode" with some tools, such as Rufus). Use the .img file whenever needing these generated PDF reports or planning to customize ShredOS (`autonuke` setups, kernel parameters, ...). The .img file also allows direct interaction with the filesystem and modification of the GRUB boot menu, e.g. appending of kernel parameters, which the .iso file does not support due to filesystem constraints.

 hdparm has many uses and is a powerfull tool. Although Nwipe will be adding ATA secure erase capability, i.e using the hard disk own firmware to initiate an erase, nwipe currently wipes drives using the traditional method of writing to every block. If you want to initiate a ATA secure erase using the drives firmware then hdparm will be of use.
