Please choose the specific method according to your needs. Next, let's look at how each method works. We will start with the simplest method. Hopefully, one of the methods will be useful to you.
Fix 1. Check If PC Meets the Minimum System Requirements for Windows 10
If you want to install Windows 10 on a low-end computer, you should first check that the current computer in use has the minimum system requirements to meet the update:
- Processor: 1 GHz or faster processor or SoC
- RAM: 1 GB for 32-bit or 2 GB for 64-bit
- Hard Disk Space: 16 GB for 32-bit OS or 20 GB for 64-bit OS
- Graphics card: DirectX 9 or later with WDDM 1.0 driver
- Display: 800x600
Follow the steps to check the system specifications:
Step 1. Press "Windows + R" and open the run window.
Step 2. Type "dxdiag" and hit Enter to see the system requirements.
If your computer does not meet these requirements, you may encounter a Windows 10 ISO fail to install error. And you need to add or replace the hardware. Or, it is better to use the current system, which is more stable and secure.
If your computer meets the system requirements, the Windows ISO failed to install error may be caused by other reasons, and please continue to check the solution.
Fix 2. Remove Unnecessary External Hardware
You can unplug unnecessary devices. The Windows 10 ISO failed to install error may be caused by the insufficient power supply unit to support all the devices connected. This method can potentially solve potential power management problems caused by peripheral devices.
Possible external drives: headphones, USB flash drives, printers, scanners speakers, and other external drives.
Remove unnecessary drives:
Step 1. Right-click on the external drive in the toolbar below.
Step 2. Select "Eject" to allow the external drive to be safely removed.
By disconnecting unnecessary hardware, you can narrow the scope of the problem. And please go to the next method if this method does not work to resolve the error.
Fix 3. Uninstall Incompatible Hardware Programs
Mismatched software may cause Windows 10 ISO fail to install error when upgrading Windows. You can uninstall the unimportant or incompatible applications to help you solve the problem.
Step 1. Open "Control Panel" and choose "Programs and Features."
Step 2. Right-click the incompatible programs and select "Uninstall."
Fix 4. Run Troubleshoot to Fix Update Failures
You can follow the below steps to directly run Troubleshoot to fix Windows update KB5020030/KB5008212/KB5013945/KB4592449/KB5021655 fail to install error:
Step 1. Type: troubleshooting in the search > Go to System and Security > Tap Fix problems with Windows Update.
Step 2. Tick Advanced > Enable and check Apply repairs automatically.
Step 3. Tap: Run as administrator (you may have to enter your passcode first) > Then click Next to finish the process.

Step 1. Press Windows + X and choose Command Prompt (Admin).

Fix 8. Extend EFI Partition Space
If you are running out of space on your EFI partition, it will also prevent you from updating. I recommend updating after using the extended partition function of EaseUS Partition Master. This tool can resize partitions and merge non-adjacent partitions.
And it is also easy to use. Follow the steps to increase the partition space.
Step 1: Locate and select the target drive/partition
Launch EaseUS Partition Master and go to Partition Manager, select the target drive/partition to adjust its size, right-click on it and choose "Resize/Move".
![choose the partition](/images/en/screenshot/partition-manager/screenshots/resize-move-partition-1.png)
Step 2: Resize or move the partition
1.To shrink the partition, simply drag one of its ends to free up unallocated space. Once done, click "OK".
![drag the mouse leftwards to resize partition](/images/en/screenshot/partition-manager/screenshots/resize-move-partition-2.png)
2. To extend the partition, make sure that there is unallocated space aside (if there isn't, follow the above steps to create some). In the same way, drag your mouse into the unallocated space. Click "OK".
![drag the mouse leftwards to resize partition](/images/en/screenshot/partition-manager/screenshots/extend-partition-2.png)
3. To move a partition position, you need to leave unallocated space next to the target partition. If no, free up some unallocated space first.
Right-click the target partition, select "Reize/Move". Then drag the whole partition leftward or rightward to adjust its position. Click "OK" to confirm.
