The error code 0xc1900101 - 0x30018 typically occurs during the installation of Windows (especially during major updates like the upgrade to Windows 10 or subsequent large feature updates) and is usually related to driver conflicts or settings that are not compatible with the new version of the operating system. This error can be particularly frustrating as it often causes the installation to fail after reaching a certain percentage, followed by a rollback to the previous version of Windows.
Understanding and Resolving Error Code 0xc1900101 - 0x30018:
Root Causes
- Driver Issues: The most common cause for this error is incompatible, outdated, or faulty drivers. This includes graphics drivers, network drivers, and other critical hardware drivers.
- BIOS Settings: Incorrect BIOS settings or an outdated BIOS firmware can conflict with the Windows upgrade/installation process.
- System File Corruption: Corrupted system files can hinder OS upgrades.
- Hardware Conflicts: Sometimes, connected external devices create conflicts during an OS update.
- Insufficient Disk Space: Adeqaute free disk space is crucial for performing upgrades as temporary files need to be created during the process.
Troubleshooting Steps
Step 1: Update Drivers
Before attempting another upgrade:
- Update all your device drivers including graphics card, motherboard chipset, network adapters, etc., from the manufacturer's official website.
- Use Device Manager in Windows to locate any devices marked with a yellow exclamation point and attempt to update those drivers directly.
Step 2: Run Windows Update Troubleshooter
- Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
- Run both "Windows Update" and "Internet Connections" troubleshooters.
Step 3: Check Your Disk Space
- Ensure you possess enough free space on your hard drive (at least 20GB).
Step 4: Disconnect Unnecessary Hardware
- Disconnect non-essential peripherals such as USB drives, external hard disks, printers etc., leaving only mouse, keyboard and monitor connected.
Step 5: Perform a Clean Boot
- Start your computer using minimal set of drivers and startup programs (through System Configuration -> Selective startup).
Step 6: Check System Files Integrity
- Use Command Prompt Admin mode and run
sfc /scannow followed by DISM /Online /Cleanup-image /RestoreHealth.
Step 7: Adjust BIOS/UEFI Settings
- Restore default settings in BIOS/UEFI which might resolve potential conflicts between existing configurations and new operating system requirements.
Step 8: Upgrade BIOS/UEFI Firmware
If possible:
- Visit your motherboard’s support page and check for any firmware updates that might make your system more compatible with newer versions of Windows.
Alternative Solution
If all else fails:
- Perform a Clean Installation: Backup important data and perform a clean install rather than an upgrade. This method erases all existing data on your primary disk but might circumvent issues related to legacy software or driver remnants causing conflicts.
Following these troubleshooting steps should significantly help in overcoming the error code 0xc1900101 - 0x30018 when upgrading/installing Windows. In case persistent difficulties occur despite these efforts, consider contacting Microsoft Support or visiting online forums specific to Microsoft products for additional assistance tailored specifically towards complex scenarios not covered by typical troubleshooting methods.
