Normal PC#



How can I check if I'm 64-bit?

Windows: Consult Microsoft's guide.

MacOS: Click the and choose About This Mac. Anything other than Intel Core Solo or Intel Core Duo (Intel Core 2 Duo is 64-bit) under CPU is 64-bit.

Linux: Run getconf LONG_BIT in a terminal. The resulting number should be 64.

  • A 64-bit CPU, from no earlier than 2009.
  • A minimum of 4 GBs of RAM and 25 GBs of storage.
  • A spare USB drive, with a minimum size of 4GBs.
  • A network connection, for the installer
  • Time
  • (Optional) Basic YAML knowledge

Download blendOS#

Go to the Download page.

Flash a USB#

Download Etcher from and plug in your USB.

You can click the button below to automatically download and flash the ISO:


If you already have an ISO, pick your downloaded ISO, your USB drive, and hit Flash!.


Open your ISO in Rufus, and hit START. When prompted, choose DD Mode!

Download Ventoy and extract it to a folder.

Download Ventoy

Once downloaded, open Ventoy2Disk.exe or

Choose your drive at the top. Then make sure Secure Boot Support is checked.


Choose Install.

Download our ISO and copy it to the root of the drive labeled Ventoy.

Open a terminal and type the following:

sudo dd if="path_to_blendos.iso" of="/dev/sdX" bs=4M status=progress

Replace /dev/sdX with your USB's identifier (found via lsblk)

Install blendOS#

Now we can get on to actually installing this distro.

Boot the USB#

First, find your one-time boot key. You can do this by searching:




Tip: Common boot keys include: F12, Esc, F2, F10 and F11.

Plug your USB in and spam that key while turning on your PC.

You should see a device list, choose your USB device. It will be listed under its brand name or as EFI USB device. If you get booted to a diagnostic screen or get a "Secure Boot violation" error, see the below abstract.

Ventoy Users: 'Security Violation' Error
Video Demonstration

If you get an error screen saying there was a 'Security Violation,' follow the steps below:

1. Press Enter to load MokManager

2. Press any key to begin key management

3. Choose Enroll Key From Disk

4. Choose VTOYEFI

  • The controls are arrow keys to move and Enter to select


6. Choose Continue, then Yes, and finally Reboot

7. Boot from the USB again, as the issue should be resolved

If it is still not working, try 'Hash Enrollment,' as detailed in Ventoy's guide.

Non-Ventoy Users: Disabling Secure Boot

Enter your BIOS setup and find a section called Secure Boot (or if it doesn't exist, look under Boot). Turn Secure Boot (also called UEFI Secure Boot) off.

If you want to know what Secure Boot is, see Microsoft's article on it.

If you see a sort of settings menu, go to the Boot section, and change the boot order so that your USB drive is at the top. Then save your changes and reboot.

If you're on legacy BIOS, you'll see a bootscreen, just press Enter. If you're on UEFI blendOS will just load.


Eventually the desktop will load and look something like this:


Running the installer#

Click Start.


Once you start, you now need to choose your installation disk.

You can either choose a disk ( THIS WIPES THE CHOSEN DISK AND ALL DATA ON IT!) or go to Manual Partitioning.


Manual Partitioning#

Oh, wait, Rudra wrote this guide for me 😑.


After clicking Switch to Manual Partitioning, choose Partitioning How-To under Quick Actions. This will explain exactly what to do.

A copy of the file that opens has been provided here for reference:

"Reloading the list of available partitions" means click that little refresh icon (refresh)

I set up partitioning and the Next button is greyed out!

This is a strange bug, simply switch to automatic partitioning then back to manual partitioning again.

You will see a summary and the installation will begin. Wait for first build to finish, then click Next and finally, Reboot.

First Boot#

On first boot, a GNOME welcome window will open. From here, it's pretty self-explanatory. Set your language, keyboard, timezone, etc.


After you click Start Using, your desktop will open.

blendOS is now installed!

Now, continue with the Post-Install section.
