Fix 0xC000026C: Driver Failed to Load

The 30-Second Fix: Run SFC and DISM

Don't overthink this — most of the time the system file checker catches it. Boot into the Windows Recovery Environment (WinRE) by powering on and off three times to trigger automatic repair. Then go to Troubleshoot > Advanced Options > Command Prompt.

Run these two commands in order:

sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

DISM /Image:C:\Windows /Cleanup-Image /RestoreHealth

Let both finish. If SFC finds corrupted files and repairs them, reboot. That's it for about 30% of cases. If you still get the error, move on.

The 5-Minute Fix: Safe Mode and Driver Rollback

The culprit here is almost always a storage controller driver — Intel RST, NVMe, or a SATA AHCI driver that got borked by a Windows Update or a failed driver install.

Boot into Safe Mode. You can get there from WinRE: Troubleshoot > Advanced Options > Startup Settings > Restart. Hit 4 for Safe Mode.

Once logged in, open Device Manager (right-click Start). Look under Storage Controllers or IDE ATA/ATAPI controllers. Any device showing a yellow triangle? Right-click it, choose Properties > Driver > Roll Back Driver. If rollback is greyed out, just Uninstall Device (check “Delete the driver software for this device”). Reboot normally — Windows will reinstall the generic driver.

If you're on an older machine with an Intel chipset (6th gen or older), the Intel RST driver is famous for this error. Uninstall it and let Windows use the standard AHCI driver. Don't bother with the latest Intel driver package — it rarely helps here.

The 15+ Minute Fix: Registry and Boot Volume Repair

If you're still stuck, the driver entry in the registry is shot. You'll need to edit it manually. Boot back to WinRE command prompt.

First, find your Windows drive letter. It's often D: in WinRE, but check:

diskpart
list volume
exit

Now load the registry hive:

reg load HKLM\TempSystem D:\Windows\System32\config\SYSTEM

Navigate this key:

HKLM\TempSystem\ControlSet001\Services

Look for a subkey named after a driver that starts with stor, nvme, iaStor, or amdsata. Common ones: storahci, iaStorV, nvme. Check the Start value. It should be 0 (boot start) for critical drivers. If it's 4 (disabled), change it to 0. If it's missing, you'll need to create it.

Also check ImagePath — if it points to a missing file (like \SystemRoot\System32\drivers\something.sys and that file doesn't exist), delete the entire subkey for that driver. Yes, delete the offending driver's key. Windows will rebuild it on next boot.

Unload the hive:

reg unload HKLM\TempSystem

Reboot. If the error persists, you've got deeper corruption — try a repair install or check the disk for bad sectors:

chkdsk C: /f /r

But honestly, if you've reached this point and it's still broken, I'd backup your data and do a clean install. You've lost more time than the driver is worth.

Real-world trigger: This error pops up most often after a Windows Update KB5025239 or similar patch that replaces the storage driver. If you're running an Intel Optane system with an older RST driver, that's your smoking gun.
