CPU Not Compatible

To install Windows 10 on your PC, the processor (CPU) must support the following features: Physical Address Extension (PAE), NX, and SSE2. Most CPUs have support for these features, so if you receive this error, it is likely because the NX feature is not enabled on your system.

If your computer does support these extensions, you could still try using ISO media. In some instances, you might have to switch from your current architecture,  64 to 32 bit since these requirements mostly affect installation of 64 bit Windows 10:

See instructions: How to download official Windows 10 ISO files

CompareExchange128 error

This likely means your computers processor (CPU or brains of your computer) lacks an important instruction called CMPXCHG16B.

In order to install a 64 bit version of Windows 10, this instruction must be present.

  • Updating your computer BIOS and Chipset drivers can sometimes resolve this issue.
  • Your CPU is probably too old and is not supported.
  • Your best option in this case is to downgrade to a 32 bit version of Windows 10 instead, even if you are presently running a 64 bit version of Windows. If you prefer having a 64 bit version based on factors such as the amount of installed RAM, chore associated with having to reinstall applications and hardware drivers, then its best you stick with the current version of Windows installed.

Try the following:

- Disable Hyper-Threading in your BIOS

- Disable Virtualization  in your BIOS

- Check if there are any BIOS updates for your computer

KMODE_EXCEPTION_NOT_HANDLED If you have compatible hardware and your computer stops responding, disable any unnecessary hardware. Remove universal serial bus (USB) devices; remove or disable network adapters, sound cards, and serial cards; and then restart the installation.
Incompatible Video card.

Uninstall Video Card adapter.

Press Windows key + R

Type: devmgmt.msc

Expand: Display adapters

Right click listed Display Adapter

Click Uninstall

Start setup.

When setup completes successfully, install the latest driver updates for device through Windows Update or from the manufacturers website using compatibilut mode if necessary;

Note: Some older video cards might be incompatible with Windows. It likely means the graphics adapter has or is approaching End of Life status which limits the level of support the manufacturer can provide. The card will likely function just fine for general purposes, just don't expect it to work well for scenarios such as playing games. There might even be glitches with certain casual games not working well at all.

If the Get Windows 10 app still prevents installation after uninstalling the card, try using the ISO media to upgrade:

If you installed a new video card without uninstalling the old video card, you might have reinstall the old card, then uninstall it properly through device manager.

Check the manufacturers website to find out the status of the video card. Check if there are at least Windows 8.1 drivers available. If there are no drivers available or manufacturer support options, you should purchase a new video card.

Couldn't Update System Reserved Partition

You get this error if the System Reserved partition in Disk Management is too small. The system reserve partition needs to be at least 450 to 500 MBs.

Press Windows key + R

For this example, I will be using Ease us partition manager:

  • After installing Easeus partition manager, launch the program.
  • Select the system partition where Windows is installed.
  • Click Resize/Move button on the toolbar

Under Decide size and position, use the knob and drag to the left until a desired amount of space is allocated. Look in the Unallocated Space Before: field to see how much. Once that is done, release.

You will now see an unallocated amount of disk space created. Click OK

Click Apply and OK to confirm changes. Your computer will be restarted to apply the changes.

After restart, log in and launch Disk Management – press Windows key + R > type: diskmgmt.msc then hit Enter on your keyboard.

Select the System Reserverd partition then right click it and click Extend Volume

Select the Unallocated space we created earlier then click Next then click Finish

You should now have a large enough System Reserved partition to accommodate Windows 10 setup.

Unfortunately, I continue to get error "0x8007002C - 0x4000D - The installation failed in the SECOND_BOOT phase with an error during MIGRATE_DATA operation." As per the recommendations, I tried the solutions identified for error 0xC1900101-0x4000D and I still get the same error. Is there any way that I could get some assistance?

i don't agree about 0xc000021a
because i need to keep my files

then if you dont want your data lost because change the partition type , you can use rufus when you installing windows

then change Partition scheme and target system type to BIOS - MBR  when you burn windows files to CD/DVD/Bootable

This is the third machine i've tried with a valid code that does not install

0x8007002C 0x4001E after 100 % completion, so far seems undocumented code..

Error Code

0xC1900101 - 0x30018

The installation failed in the FIRST_BOOT phase with an error during SYSPREP operation

Have disabled my AV, unplugged all unnecessary USB's and have tried to update using the download file several times.

Each time I am receiving the above error message after first phase of installation (Copying Files) and immediately after it starts the "Installing apps and drivers" stage kicks me out to "Restoring Previous version of Windows"

The error code listing states an answer as "Suggest using IDE to install"

I am on a modern system that no longer requires IDE to operate, and is not fitted with IDE slots, only SATA Ports

 My install failed with 0x80073B92 - 0x20009 failed in the SAFE OS phase

WE have had three admins, trying everything we could think of and this is what we think.

Will only install on Retail, we tried VOlume License 7 SP1 upgrade did not work, We tried OEM upgrade, did not work.

We are copying the Entire Media to the workstation instead of DVD which has to t be an 8 GIG dvd.

COuld not get it to install on a USB Key.

Typical Microsoft, like IE 11, EXPLODER.


I uploaded the Windows.msi file and the media creation tool to

a window 7 SP1 and finally now its working.

i have tried six times now five times it downloads,create the media,authorizes,and then just says windows 10 setup could not start reboot your pc and try again....and one time it just said....something error codes or anything....just a big circle of ****....

error code: 0xc1900101-0x40017

I have tried everything given over here. In the command prompt as suggested the steps for some other error by renaming, i tried but it failed saying access denied when trying to rename with the same code. I disabled my AV, no USB attached, all the drivers in my PC updated, still for no  use. setup exits after the second phase is complete i.e. installing features and drivers and i am told that windows did not start properly with the options restart and advanced options to repair or restore. Restart gives the same problem again and again, advanced option do no good and in the end I am reverted back to my old OS win 8.1. I tried this over 3 times. It took my whole day :(. I even tried with the ISO media, but it says something happened and then stops.
Now what should I do? Any help????

Initially had the 0020 error fixed that but now my install keeps hanging whenever it has to reboot.. it just sits on the BIOS splash screen and will not advance back to continuing the install.

the BIOS is not something i have ever wanted to mess with.  but am familiar with what is on there.

Is there something that needs to be changed on there to stop this hanging?
