But if you faced this issue, it may not be so funny to you. So we managed to find the solution for this strange error message, and we hope it will work.
Here’s what you need to do to “make something happen” with the installation of your Windows 10:

Solution 3 – Error 80240020 while installing Windows 10
Some users who received Windows 10 as a free upgrade through Windows Update received an unexpected error 80240020. The reason for this error is reportedly due to the overloaded Windows servers, which may cause you to receive corrupted download files.

- Go to $Windows.~BT folder in C: and make sure you checked Hidden items option in the toolbar.

Wait for a couple of minutes and then check if Windows Update started to download Windows 10 again. Once the system is downloaded, you’ll get the message “Preparing for Installation”.

Solution 4 – Disconnect additional monitors and other peripherals
According to users, your Windows 10 installation can become stuck due to multiple monitors. Several users reported various issues while using two monitors during the setup.
It seems that Windows 10 setup can’t handle two monitors, and in order to fix this problem, you just need to use a single monitor. Disconnect all additional monitors and try running the setup with just a single monitor and check if that works.
In addition to your monitor, sometimes other USB devices can cause this problem to appear. However, you can fix the issue simply by disconnecting all other USB devices. Couple of users reported that their USB hub was the issue, but after disconnecting it, the installation completed without issues.
Solution 5 – Remove the installation media
Many users reported that their setup was stuck during the expanding Windows files process. To fix the problem, it’s advised that you temporarily remove your installation media and insert it again.

According to users, sometimes your Windows 10 installation can become stuck due to your BIOS configuration. To fix the problem, you need to access BIOS and make few adjustments. To do that, just keep pressing Del or F2 button while your system boots to enter BIOS. If you have problems entering BIOS, be sure to check your motherboard instruction manual and see how to access BIOS properly.
According to users, sometimes the following features can cause this problem to appear:
- Legacy Floppy Drive Support
- Intel SpeedStep
To fix the problem, simply disable these features and check if the issue is resolved. Few users reported that HyperTransport feature can cause this issue to appear, and to fix it, you need to set KN HT Speed to 1X and KN HT Width to 8.
After disabling these features, check if the problem is resolved.
Solution 7 – Remove few RAM modules
According to users, your Windows 10 installation can sometimes get stuck due to the amount of your RAM. Several users reported this problem while trying to install Windows 10 on a PC that has a large amount of RAM.
To fix the issue, users are suggesting to remove few RAM modules from your PC and check if that helps. According to users, they had this issue while using 12GB of RAM, but after reducing the amount of RAM to 6GB, the issue was completely resolved and Windows 10 installed without issues.
