Thanks for your feedback.

You need to first prepare the ISO file:

Prepare Windows 10 ISO file

After you have downloaded the Windows 10 ISO, you need prepare it, this is especially important for Windows 7 users..

After obtaining the .iso file you can use the built in Disc Image burning tool or Microsoft .iso to USB/DVD tool to create a bootable DVD or USB (requires a blank DVD or USB flash stick of at least 4 GB).

After downloading the .ISO file, right click it and click Burn disc image

Insert a blank DVD

Windows 8/8.1 users can mount the .ISO file and start the upgrade automatically. Learn more here

Important:

If you are creating a bootable USB thumb drive, make sure the thumb drive is first formatted as FAT32.

Connect the thumb drive

Right click thumbdrive

Make sure FAT32 is selected as the file system.

For UEFI based systems

If your computer is UEFI based, these are normally systems that come pre-loaded with Windows 8 or later, you will need to prepare the ISO file for such a configuration or you will receive an error message during setup. The thumbdrive needs to be formatted as FAT32 and use the GPT partitioning scheme. To do this, you need to use Rufus, a small tool you can download for free.

After you have installed Rufus:

  • Launch it
  • Select ISO Image
  • Point to the Windows 10 ISO file
  • Check off Create a bootable disk using
  • Select GPT partitioning for EUFI firmware as the Partition scheme
  • Choose FAT32 NOT NTFS as the File system
  • Make sure your USB thumbdrive in the Device list box
  • Click Start
  • Close when complete

Once you have your Windows 10 installation media ready, all you need to do is boot from the disc or USB thumb drive to begin setup.

To learn how to change your BIOS options to boot from the DVD drive, see the following tutorial:

Once your computer is set to boot from the DVD, you should see this option.

If you are installing from a thumb drive, see the following instructions how to prepare your computer to boot from one:

How to Boot From a USB Drive or CD on Any Computer

When you’re troubleshooting your computer or installing a new operating system, you may need to “boot from a disc” or USB device (like an external hard drive or flash drive). Here’s what that means—and how to do it.

When you press the power button on your computer, it boots up from its internal hard drive, where your operating system (usually Windows or macOS) is stored. But sometimes you need to boot into something different. Maybe you need to boot from your Windows installation disc to reinstall Windows, or perhaps you need to boot from a system rescue disc to solve a problem with your machine. You may simply want to run a different operating system on your computer.

On a Windows PC

Every Windows PC is different. Some PCs are already set up to search for a USB option before defaulting to the operating system on the internal hard disk. But once you get into your system’s boot menu, you should be able to find what you’re looking for.

Here’s how to boot from a CD or USB drive on a PC:

Restart your computer

Restart your computer and wait for that first screen to pop up. Often, it’ll say something like “Press F12 to Choose Boot Device” somewhere on the screen—the requested function key could vary depending on your machine. Press that key now.

Wait a second

Give it a moment to continue booting, and you should see a menu pop up with a list of choices on it. Highlight your preferred CD or USB drive and press Enter.

Alternatively, you can set your computer to always check for a bootable CD or USB drive and change the boot order. That way, when you have an external disc inserted, your machine will boot from it automatically, and when you don’t, it’ll head into your regular operating system. To set this up, follow these instructions.

Restart your computer and watch for the first screen that shows up when you boot. You should see a message like “Press DEL to enter SETUP” or something similar (the requested key may vary depending on your machine). Press the noted key on your keyboard and wait for setup to start.

Select ‘Boot Device’

You should see a new screen pop up, called your BIOS. This is where you set a lot of low-level settings for your computer. BIOS menus are configured differently across machines, but you should see instructions for how to navigate yours (i.e., which keystrokes to use) somewhere in the window.

Using those instructions, look through your menu options (be careful not to change anything else) for a setting called “Boot Device,” “Boot Order,” or something similar. Select that option.

Choose the right drive

From the menu that pops up, choose your computer’s disc drive and press Enter. If you’re trying to boot from a USB drive, choose that option. It might be listed on its own or under a sub-menu like “Removable Devices.” Press Enter. Depending on your BIOS, you may need to use the Page Up and Page Down or +/- keys to move your selection to the top of a list instead. Again, use the directions listed on your specific machine.

Exit the BIOS

Follow instructions to exit out of your BIOS and save your changes. Usually, this option is under “Exit” or “Save and Exit” on the main menu or available via a keyboard shortcut listed somewhere on your screen. Depending on your BIOS, you may have to confirm your selection again.

Reboot

Your computer should restart automatically. Make sure your CD or USB drive is in your computer. If you’re prompted to “Press any key to boot from external device,” do so. Your computer should boot into the CD or USB drive instead of your normal operating system.

From there, you can follow the on-screen instructions to install Windows, troubleshoot issues, or do whatever else it is you need to do.

On a Mac

Booting from a USB or CD is very, very easy on a Mac. One way to do this is to open System Preferences > Startup Disk. You’ll see your built-in hard disk as well as any compatible operating systems and external drives.

Click the lock icon at the bottom-left corner of the window, enter your admin password, select the startup disk you want to boot from, and hit Restart. This method will save your startup disk preference until you go through this process again to choose a different option.

To do a one-off boot from a USB, you’ll use the Startup Manager instead. Here’s how it works:

Boot Disk – Guide for Windows XP, Vista, 7, 8, 8.1, 10

This guide is about boot (or startup) disks for the following Windows versions: Windows XP, Vista, 7, 8, 8.1 or 10.

What is a boot disk

A boot disk (or a startup disk) is a recovery media (CD, DVD or floppy disk for older Windows versions) that you can use to start Windows, if it became damaged or corrupted somehow.

The term “boot disk” was mostly used in connection with Windows XP (and older versions) and, in some cases, with Windows Vista. For Windows 7, Windows 8 and Windows 10 the “boot disk” term is mostly replaced with the term “recovery disk” (sometimes also named as a “repair disk” or “restore disk”).

NeoSmart Technologies has extensive guides on how to create recovery media for all major PC manufacturers that have their own software for recovery procedures and a recovery disk for all Windows versions (XP, Vista, 7, 8, 10).

If you have a computer from any of the following manufacturers, read that guide too. Most PC manufacturers with computers that have Windows installed also have a recovery partition that you can make use of to restore or repair your computer. Some older models had only a recovery disk (as a CD, DVD etc.) or only the recovery partition.

Our list of recovery media guides for specific PC manufacturers: Dell (including the guide on the recovery partition), Acer, Asus, Gateway, Toshiba, HP, Lenovo.

A boot or startup disk is not an installation disk! You can not use a boot disk to install Windows. To install Windows, use your original Windows installation disk.

You can use the following formats to create a disk:

  • CD or diskette (floppy disk) for Windows XP
  • CD or DVD for Windows Vista
  • CD or DVD for Windows 7
  • CD or DVD or USB for Windows 8
  • USB for Windows 8.1 or Windows 10

Windows 10 users

You can use Easy Recovery Essentials as a boot or startup disk (now known as a recovery media) for computers with Windows 10 installed to repair or restore your computer.

Create boot disk for Windows XP

The original Windows XP installation CD itself acts as a boot or startup disk that you can use and run Recovery Console (Command Prompt) to repair your computer with.

If you already have the installation CD, follow these steps to boot into Recovery Console and the Command Prompt of Windows XP:

  1. Insert the CD in the disk drive and restart your computer
  2. Press any key, when prompted to boot from the CD
  3. Press R to open Recovery Console, at the “Welcome to Setup” screen

Windows XP Press R for Recovery Console

If you don’t have the CD, you can create a bootable diskette if your computer has a floppy disk drive to boot into MS-DOS. You need to be able to boot into Windows XP to create this diskette.

To create the boot diskette for Windows XP, follow these steps:

  1. Insert a diskette in your computer’s floppy disk drive
  2. Go to My Computer
  3. Right click on A:\ , this is usually the drive letter that holds the diskette
  4. Click Format
  5. Check the “Create an MS-DOS startup disk” option

Create MS-DOS startup disk option

Once you have the diskette created, follow these instructions to use it when you need it:

  1. Make sure the disk is in write-protect mode
  2. Insert the disk in the floppy disk
  3. Restart your computer
  4. Follow the instructions on the screen as you boot the system from the diskette

You can also create a set of setup/boot disks that will allow you to bypass the need for a bootable CD-ROM (and then continue a reinstallation of Windows XP) by following these instructions:

  1. Download the setup program file for the Windows XP you have installed:
    • Windows XP Home Edition with Service Pack 2
    • Windows XP Professional with Service Pack 2
  2. Extract the files
  3. Type the drive where your floppy disks is – example: A: – and hit Enter when you receive this message:
  4. Insert the first blank disk in the floppy drive when you receive this message:
  5. Continue with the process until all 6 disks are created
  6. Boot from the first created diskette. Make sure you have the installation CD at hand to be used during a reinstallation process.

Create boot disk for Windows Vista

If you already have the Windows Vista installation disk, you can use it to recover or restore your computer.

If not, go to the Create the disk section instructions to learn how you can create the disk (read Prerequisites before).

If you don’t have the installation disk and can’t boot into Windows, go to Download boot disk and use Easy Recovery Essentials’ Automated Repair function to fix boot errors automatically.

To repair your computer, if you have the Windows Vista installation disk, follow these steps:

  1. Insert the disk
  2. Restart your computer
  3. Press any key to start Windows from the disk. If the “Press any key” message doesn’t appear, please check your BIOS settings as you need to boot from the DVD first.

If you want to create a boot disk, follow the instructions from Prerequisites and then the Create the disk instructions.

Prerequisites

You must verify what version of Windows Vista you have before you create the boot or startup disk. If you have any Service Packs installed, you need the recdisc.exe file from the System32 folder to be from a Windows Vista system without any Service Packs (SP) installed.

To verify this, follow these steps:

  1. Go to Control Panel
  2. Click on System
  3. Go to the System type section
  4. Check if you run a “32-bit” Windows Vista or a “64-bit” Windows Vista

Windows Vista System Type

The Windows Vista – Windows Edition section

If you have the Windows Vista with Service Pack 1 (SP1) or Service Pack 2 (SP2) installed, you need to replace the recdisc.exe file.

Your Windows Vista has SP1 or SP2 installed only if it’s mentioned in the Windows edition section, above the “System type” section.

If you have a Service Pack installed, follow these steps to replace the recdisc.exe file before you continue with the Create the disk section steps:

  1. Copy an original recdisc.exe file from a Windows Vista without SP. This file will be replaced with your current recdisc.exe.
  2. Copy this file to your Desktop
  3. Right-click on the file > Properties
  4. Go to the General tab
  5. Click Unblock. If this option – Unblock – doesn’t exist in the General tab, skip this step.
  6. Click OK
  7. Go to C:\Windows\System32\ (from My Computer > C:\ > Windows > System32)
  8. Find the recdisc.exe file from this folder
  9. Make sure you have permissions to make modifications to this file. Right-click on this file > Properties
  10. To have a backup of your original recdisc.exe file, rename it to recdisc.exe.backup or similar
  11. Go to the copied recdisc.exe file and copy it (Right-click > Copy)
  12. Paste it in the System32 folder, to overwrite your current recdisc.exe file
  13. If you didn’t renamed the original file, confirm that you want to replace it (click Copy and Replace, when prompted)

Once these steps have been completed, move to Create the disk below to create the boot/startup disk for Windows Vista.

Creating a boot disk

Please read Prerequisites above before continuing with these instructions.

These steps allow you to create the boot or startup disk (a recovery media) for Windows Vista that you can use in emergency cases.

  1. At Start, type recdisc.exe in the search field
  2. When the search results appears, click on the top result item
  3. Insert a blank DVD in the disk tray. You can use CDs or DVDs for this
  4. Select the disk drive from the “Drive:” list
  5. Click Create disc. If after clicking Create disc, the system shows a message about the installation disk – Insert Windows installation disc – you need the original installation disk as your version of Windows Vista is missing the necessary files to continue with the process.
  6. Wait for the recdisc.exe utility software to finish the procedure

    Create boot disk for Windows 8/8.1/10

    In Windows 8 or 8.1, you can refresh, reset or restore your computer. These three actions have different outcomes:

    • Refresh will not affect your files. Windows 8/8.1 will reinstall any applications you installed and create a copy of these applications on your desktop. Even so, backup your data before you do a refresh.
    • Reset will remove all your personal files and delete any settings or configuration you did on your computer.
    • Restore will restore your computer to an earlier point in time, if System Restore is available and enabled.By default, Windows 8/8.1 creates restore points whenever you install new applications or do Windows updates. If you haven’t disabled System Restore, restoring your computer via this utility should work.

    If you want to create the boot disk, find the instructions below:

    • If you have Windows 8, not 8.1, follow Create the disk as a CD/DVD
    • If you have Windows 8.1, not 8.0, follow Create the disk as a USB drive. For Windows 8.1 you can only use USB drivers to create the disk.
