Common Windows Installation Problems & What Causes Them

Before diving into solutions, here are the frequent issues people run into:

  1. “No bootable device / no operating system found”
    Usually means the installer can’t find a valid system to boot from — could be bad BIOS settings, messed-up disk partition, or hardware failure.

  2. Blue Screen of Death (BSOD) during or immediately after install
    Error codes like 0xC000021A, 0x0000007B, or others suggest driver or disk issues.

  3. “Setup could not configure Windows to run on this hardware”
    This often occurs when Windows can’t find the right driver or on certain storage controllers (e.g. NVMe, RAID).

  4. Installer freezes, gets stuck at a percentage (e.g. “Installing features 30%”)
    Caused by incompatible hardware, failing drive, faulty USB media, or power issues.

  5. Activation or licensing errors after install
    Even if Windows installs, sometimes you’ll see “Windows is not genuine” or activation errors.

  6. Missing drivers after install
    E.g. network adapter, graphics card, or chipset drivers not found, leaving features unusable.

Step-by-Step Troubleshooting (DIY)

Here’s a methodical approach to try before bringing your machine in:

1. Check BIOS / UEFI Settings

  • Ensure Secure Boot is disabled (for certain installs) and Legacy Boot / CSM is appropriate for your hardware.

  • Confirm the boot order: USB or DVD first, then internal drive.

  • On SSD / NVMe drives, check if the controller mode is AHCI or RAID, and match that to how Windows was configured.

2. Verify Installation Media

  • Recreate your USB installer using Microsoft’s official tool (for Windows 10 / 11).

  • Use Rufus or similar to build the installer, and ensure you choose the correct partition scheme (MBR vs GPT) depending on UEFI or legacy BIOS.

  • Try a different USB port (prefer USB 2.0 rather than USB 3.0 for stability in some systems).

3. Run Diagnostics on the Hard Drive / SSD

  • Use chkdsk /f or chkdsk /r from a recovery environment.

  • Use manufacturer tools (Samsung Magician, CrystalDiskInfo, etc.) to test drive health.

  • If the drive is dying or has bad sectors, replace it before installation.

4. Use Disk Partition Tools Wisely

  • Delete all existing partitions during setup and let Windows recreate them if possible (be careful: this erases data).

  • If dual-booting, ensure partitions are properly aligned and sized.

  • Watch for leftover OEM partitions or recovery partitions interfering.

5. Install Drivers Early

  • Before installing optional programs, get base drivers (chipset, storage controller, network) from your PC maker’s site.

  • If the installer doesn’t detect network, you can manually load drivers during setup.

6. Address Activation / Licensing Issues

  • Use the correct Windows edition matching your license (Home, Pro, etc.).

  • If upgrading from a prior install, ensure your digital license is linked to your Microsoft account.

  • Use slmgr /ipk and slmgr /ato commands to manually activate if online activation fails.

7. Check for Firmware / BIOS Updates

  • Sometimes, outdated firmware causes incompatibility, especially with newer SSDs or chipsets.

  • Only update BIOS/UEFI if needed — it’s a potentially risky operation.

Tips to Avoid Windows Installation Issues in Future

  • Always back up your data before trying OS work.

  • Use reliable, known-good USB media and check the integrity (e.g. hash checks).

  • Keep your firmware / BIOS / driver software up to date.

  • Use surge-protected power — unexpected shutdowns during installation can corrupt system files.

  • Maintain a recovery drive or system image so you can roll back quickly.
