Prerequisites

  • A PC to install Ubuntu 26.10 on, with at least 25 GB of free space
  • A USB stick of 8 GB or larger
  • A wired internet connection (easiest) or Wi-Fi
  • A second computer to prepare the USB (the video uses Windows 11)
  • Ventoy, downloaded from https://ventoy.net

This tutorial takes about 12 minutes to complete.

This guide shows how to install Ubuntu 26.10 on your PC, from downloading the ISO to your first login, and which installer options to pick as a beginner and why. It follows the video, with the exact keys, button names and options from the recording.

New to Ventoy? The Ventoy page explains what it is, and the full Ventoy walkthrough shows the Windows steps in more detail. If you want to know how to install Ventoy on other Linux distributions instead of Windows, see the related tutorials at the bottom of this page.

Warning: this is a fresh install. Erase disk and install Ubuntu wipes the whole hard disk, and there is no disk partitioning or dual boot. Back up anything important first.

Before you start

You need a PC, a USB stick of 8 GB or larger, and at least 25 GB of free space, which is the minimum Ubuntu 26.10 requires. You will also need a second computer, or the same PC while it still runs its current system, to download the ISO and prepare the USB stick. The video does this part on Windows 11, because many people switching to Linux are coming from Windows.

A wired internet connection is the easiest and most reliable connection, because Ubuntu can download updates during the install. Wi-Fi works too, and you just connect on the installer screen. If Wi-Fi is not working for you, use a wired connection instead.

Step 1: Download the Ubuntu 26.10 ISO

Open your browser and go to releases.ubuntu.com/26.10. This is where the official Ubuntu 26.10 ISO image is. Scroll to Select an image and look for the desktop image.

If you are running an Intel or AMD CPU, click the 64-bit PC (AMD64) desktop image. Your download should start. The video skips the wait. When the download is done, open your Downloads folder, and you will see the Ubuntu 26.10 desktop image there.

Step 2: Download Ventoy

To put the ISO on a USB stick, the video uses Ventoy. It is free, and you can keep many ISOs on one stick, so the same drive can hold Ubuntu and other systems later.

Go to ventoy.net, click Downloads and scroll down. Look for the Ventoy Windows .zip file and click it. Your download should start shortly.

The ventoy.net home page with the Downloads tab highlighted.

Step 3: Extract Ventoy and open Ventoy2Disk

Go back to your Downloads folder. You should see the Ventoy Windows .zip file. It needs to be extracted, so right-click it, click Extract All and then click Extract.

Now Ventoy has been extracted. Go inside the Ventoy folder and double-click the Ventoy2Disk application. Click Yes to give administrator access. You should now see the Ventoy application.

The Ventoy folder in File Explorer with the Ventoy2Disk application highlighted.

Step 4: Select your USB drive

Connect your external USB storage device. If you do not see it in the Device menu, click the refresh button. When it appears, your USB drive is showing in the Ventoy window.

If for some reason it is not showing, open the Options menu and click Show All Devices. This should show all the hard drives on your PC, and it is turned off by default.

Warning: do not format your main drive. Make sure you select the correct drive that you want to format. Also make a backup of your USB drive first, because all information on the drive will be formatted and deleted.

The Ventoy2Disk window with the Option menu open and Show All Devices ticked.

Step 5: Turn on Secure Boot Support

In the Options menu, make sure Secure Boot Support is selected. This makes sure your Ventoy drive has secure boot support, which matters on PCs that have Secure Boot turned on.

The Ventoy2Disk window with the Option menu open and Secure Boot Support ticked.

Step 6: Install Ventoy on the USB drive

Now install Ventoy on the drive: click Install. A warning says the device will be formatted and all the data will be lost. Click Yes.

The Ventoy2Disk warning that the device will be formatted and all the data will be lost, with Yes and No buttons.

A second window double-checks that you want to format and erase the drive. Make sure you have everything backed up, then click Yes again.

When it is finished you will see Congratulations: Ventoy has been successfully installed to the device. Close that message, and then close the Ventoy application.

The Ventoy2Disk Info dialog saying Congratulations, Ventoy has been successfully installed to the device.

Step 7: Copy the Ubuntu 26.10 ISO to your Ventoy drive

Open your file manager and go to Downloads. Find your Ubuntu 26.10 ISO, right-click it and click Copy. Then go to your Ventoy drive and paste the ISO there. Wait until the ISO has finished copying to the Ventoy drive, which takes a little while, and then close the window.

Tip: for blazing fast speeds and more storage space, use an external NVMe drive. The NVMe enclosure tutorial shows how to build your own NVMe drive with an external NVMe enclosure, and the Orico M.2 NVMe enclosure page has the product details.

Step 8: Boot from the USB with the boot menu key

Shut down your computer and plug the USB into the PC you are installing on. Restart and tap the boot menu key right as it powers on. The key depends on the brand. Here are the common keys to boot into the boot menu or into the BIOS.

BrandBoot menu keyBIOS setup key
DellF12F2
HPEsc, then F9Esc, then F10
LenovoF12 (or the Novo button)F2 or F1
ASUSEsc or F8Del or F2
AcerF12 (turn on "F12 Boot Menu" in BIOS first)F2 or Del
MSI (motherboard)F11Del
Gigabyte (motherboard)F12Del
ASRock (motherboard)F11 or F8F2 or Del

Keys vary by model. The table lists the common keys. If yours does not work, check the manual of your computer or motherboard.

Tap the key, do not hold it. Tap it repeatedly right after you press the power button, with the USB already plugged in. The boot menu lets you pick the USB drive once, and the BIOS setup key opens the firmware settings, where you can change the boot order.

Acer: on some models the F12 boot menu must first be enabled in the BIOS. Press F2, go to Main, set F12 Boot Menu to Enabled, then save and restart. Lenovo: many models also have a small Novo button that opens a boot menu.

If the key does nothing: fast boot can use up your keystrokes. On a Windows PC, hold Shift and click Restart, then choose Use a device and pick your USB drive. To open the BIOS setup that way, go to Troubleshoot, Advanced options, then UEFI Firmware Settings.

The boot menu keys for Dell, HP, Lenovo, ASUS, Acer, MSI and Gigabyte are the ones said in the video. The BIOS setup keys, ASRock, the Novo button and the Acer setting come from the manufacturers' support pages and other published lists: Dell, HP, MSI, ASRock, Acer and the Gigabyte BIOS manual.

Step 9: If you get "verification failed security violation"

If you get "verification failed security violation", this is one of the Secure Boot errors. The fix only takes a minute. Click OK. When you see "Press any key to perform MOK management", press Enter.

Go to Enroll key from disk and press Enter. Choose VTOYEFI and press Enter. Then scroll down until you see ENROLL_THIS_KEY_IN_MOKMANAGER.cer and press Enter. The selected key will be enrolled into the MOK database.

Click Continue. It will ask you to enroll the key, so say yes. Then reboot, and start again from the boot menu.

Step 10: Boot the Ventoy drive and start Ubuntu

In the boot menu, select your Ventoy drive, which is the first drive shown in the video, and press Enter. You have now booted into Ventoy, and it lists the ISO files on your drive. Select the Ubuntu 26.10 ISO and press Enter, then boot into normal mode.
