This step-by-step guide will illustrate you how to upgrade to Windows 10 using ISO file, from your existing Windows installation.

Previously, we’ve seen how to make clean install of Windows 10 using an ISO file or Windows 10 installation disc in the following article:

How to make clean install of Windows 10

In that article, if you have opted for Upgrade : Install Windows and keep files, settings and applications option at step 6 then you may receive this window which advocates to upgrade the OS by running the setup file inside Windows:

The computer started using Windows installation media. Remove the installation media and restart your computer so that Windows start normally. Then, insert the installation media and restart the upgrade. [Do not select Custom (advanced) to perform an upgrade. Custom (advanced) installs a new copy of Windows and deletes your programs and settings.]

So as far as upgrading the OS is concerned, the steps are little bit different. Here you need to temporarily mount the ISO file by assigning it a drive letter, then you can proceed via upgrade.

In this article, we’ll see the step-by-step procedure to upgrade your existing Windows OS to Windows 10. Here is what you need:

1. Official Windows 10 ISO file which you can download from here:

2. A device that can run Windows 10, or that fulfills system requirements for Windows 10.

Now here comes the how-to part:

  • How can I get an Installation DVD of Windows 10? The upgrade is not working for me. Thank You for your help in the past.

  • I have been trying to get windows 10 from a free upgrade. So far it has not worked. I think the installation DVD would work. How can I get a free DVD, or can I?

  • Kapil Arya

    ^^ You can download official Windows 10 ISO from following page and burn it to DVD, if you like: microsoft.com/en-us/software-download/windows10ISO

  • are my files and there locations effected when upgrading?

  • Kapil Arya

    ^^ Nope, but if your files are of prime concern, you can create backup of them on an external drive such as USB :)

  • hello sir will i lose my games and other stufff if i upgrade from win 8.1 to win 10??help me fast

  • Kapil Arya

    ^^ Nope. But games may not work after upgrade, if they’re not supported on Windows 10.

  • No way for skipping product key ? I wanna stuck on there.

  • i just downloaded media creation tool.exe. how do i proceed from here to create an iso file for windows 10 installation

  • Kapil Arya

    ^^ You can directly download ISO file from Microsoft using link mentioned in the article. Once you’ve ISO file, go ahead with steps.

  • After restarting there is no pre-mounted drive.

  • i got to where it says the computer started using the windows installation etc….How do I actaully restart the computer once i removed the cd There is no option about restarting unless you press the power button which I did and ya operating system not found..back from scratch.

  • Kapil Arya

    ^^ In that case, physical restart is the only option left.

  • Hi, im stuck at where it says “Hi there, let’s get a few basic things out of the way, what’s your country/region?, what keyboard layout.., etc”. So yeah, i chose my settings and now it’s taking forever to apply these settings. Prior to this, i chose “keep nothing” for a clean installationg. Any help? Going over half an hour and still “applying these settings”.

  • Kapil Arya

    ^^ If it’s still there, can you go back and check Use Express settings button?

  • Hey Kapil, it appears that I am a similar situation just like Benjie, When I get to the ‘Compatibility’ report that says remove my USB install media, I have a restart button on my desktop that I can press. I go thru the stated set of instructions: 1) remove the USB media; 2) Press my restart button; 3) Wait for the machine to reboot into my old Windows 7 (32bit) Sp1 OS; 4) Wait for that start-up to complete; 5) Reinsert the USB media and tell Win-login page to restart my machine; 6) On this occurrence the same Initialize process starts all over again w/o regard for the initiating files that should have been written to my harddrive from the prior install attempt. Effectively I’m in a never ending loop with no chance of a successful continuance of the reinstall process. How can I get this issue resolved.

    Thanks in advance…

  • Kapil Arya

    ^^ If you’ve ISO file, simply start your Windows 7 go ahead with steps mentioned here 😊

  • “Your PC will restart in a few moments” it never pass

  • Kapil Arya

    ^^ Give it some time, it will pass. This depends upon your system specs.

    ^^ Download latest Windows 10 ISO file and make a clean install using it: https://www.kapilarya.com/how-to-make-clean-install-of-windows-10

  • Hi.. Everything was working fine. 2 days ago my Acer 4740G running on Windows 10 Pro 64bit is updating to its latest update, a commulative update. At 68% percent the laptop suddenly turned off due to the plug is a bit loose and it was moved a bit and boom laptop died. Now I cant open it, asking me for a bootable device. I made a bootable USB and making an install, trying for upgrade because I dont have back up of my files. Then compatibility report keeps showing (The computer started using the Windows installation media. Remove the installation media and restart your computer……). When I clicked close it brings me back to Windows setup where you choose install now or repair your computer. I dont even know how I’ll restart it. Please help me.. :( Thank you..

  • This for this guide BUT I have a computer error and I cannot load Windows. Currently I only have access to my hard drive via CMD in the TROUBLESHOOTING option in the windows installation media. Is it possible to execute your guide with just CMD?

  • Kapil Arya

    ^^ I don’t think you can just go ahead with commands in this case. You must boot from the installation disc and then go ahead with clean install: https://www.kapilarya.com/how-to-make-clean-install-of-windows-10

  • Can I use Daemon tools to mount image to a virtual drive?

  • Kapil Arya

    ^^ Sorry, can’t comment on such 3rd-party tools.

  • Hi Kapil. Came across ur post. Pls I have a windows 10 that I have been using for the past two years. Some 3 weeks ago I tried booting my system. It refused to go to the login page and remained stuck on a blue screen and rounded dots. I have tried so many solutions to no avail. Kindly help assist me sole this problem.

  • My Dell Vostro 3560 laptop was upgraded from Windows 7 Pro to Windows 10 Pro Build 1511 using an old ISO file and it worked fine. In the process, Windows 10 Pro was activated automatically for free. Then, it tried to automatically upgrade via Windows updates to Build 1809 and it stopped about 54% of the way and rolled back to Build 1511. Unfortunately, it is now no longer activated and cannot be rolled back to Windows 7 Pro anymore. The reason that Build 1809 failed may be because some drivers are not available yet for this laptop model. Hence, it ran fine at Build 1511 and I can defer further upgrades to higher Builds and only update Build 1511 with available Windows updates but I can no longer activate it. Please provide guidance to fix this issue.

  • Kapil Arya

    ^^ You can try Microsoft chat support and they should be able to help you with activation: partner.support.services.microsoft.com/en-us/contactus/windows/tech-services

  • Contrary to what all of the discussion groups are saying, Microsoft told me that upgrading from Windows 7 to Windows 10 is no longer free and that I should buy a new Windows 10 license. The initial successful upgrade to build 1511 was performed on February 22, 2019. I lost the digital license when it tried to upgrade to build 1809 and then rolled back.

  • Yea you still can free upgrade if you find Windows10Upgrade24074.exe Accessibility Version Windows 10 upgrade (includes Handicap stuff,,, think of stickykeys, etc)… But it does free upgrade from 7 to 10…

  • O’ Also I have activated and or upgraded many CPU’s to W10… Once Activated I have never seen where Microsoft Activation server Lost an Activation. Its mainly based on your Motherboard Identity. Once a MB’s W10 Activation is stored it will reactivate again and again after a wipe/reload… So if you completely wipe and install 10 from scratch after its ever been W10 activated you don’t even have to type in a Key… Just Skip that step on the install screen and once online it will again get its activation from Windows Activation Server. Activation may not happen on an upgrade install over existing OS. Do a clean full install and you should be able to automatically reactivate…

  • How to Get Genuine Windows 10 Version for Free

  • Kapil Arya

    ^^ Not possible. For genuine Windows 10 version, you need to paid the license fee.

  • Kapil Arya

    ^^ I recommend you to first update to V1903 using this guide. Then perform clean boot and see if it helps you: https://www.kapilarya.com/how-to-perform-clean-boot-in-windows-10.

  • windows 10 home won’t update to 1903 version. it keeps failing at 60%. how can I repair this. is it possible to upgrade to repair and will I keep my third part software if I do?

  • Kapil Arya

    ^^ What is the exact error you receive while it fails at 60%?

  • 9/14/2019 Using a Toshiba Satellite P55W-C5200X. I thought that making an ISO disk would help me get past the 58% without running into Error 0xc0000005. Three attempts (two-online update and one update via ISO disk without wifi so it would not add the patches) failed. What a waste of a day. Guess I’ll have to forget version 1903.

  • Kapil Arya

    ^^ You need to check log files to identify the root cause. Refer this support article: support.microsoft.com/en-us/help/928901. Refer to Microsoft Answers and start new thread and share your log files. I’m sure log experts present there will assist you.
