Here are some steps to help you fix disk partition issues during Windows installation:

Preparation

• Backup your data: Before attempting any repair or replacement operations, make sure you have backed up all important files and data on the faulty disk.

• Check the installation media: Ensure that you are using a legitimate Windows installation media (USB drive or DVD) and that it is not damaged or corrupted.

Method 1: Reinstall Windows from a Different Disk

If you have another partition on the same disk, you can attempt to reinstall Windows from there:

• Remove the faulty disk: Disconnect the faulty disk from your computer.

• Insert the other disk: Insert the disk that has another working partition and follow the installation prompts.

• Perform a fresh install: Complete the installation process, which should reinstall Windows on the new disk.

Method 2: Repair Disk Partition Issues

If you’re unable to reinstall Windows from an alternative disk or if your system is severely damaged, you can try repairing disk partition issues:

• Boot in Safe Mode: Restart your computer and press F8 repeatedly until you reach the Advanced Boot Options menu.

• Check for corrupted files: Run the “chkdsk” command (in Command Prompt) to scan for any corrupted or bad sectors on the faulty disk:

chkdsk /f /r

• Use System Restore: If you have System Restore enabled, try restoring your system to a previous point when it was working correctly:

System Restore -> Properties -> Select a restore point and click Next.

Method 3: Use the Command Line (Advanced User)

If you’re comfortable using the command line, you can use advanced tools to repair disk partition issues:

• Open Command Prompt as Administrator: Right-click on the Start button and select “Command Prompt (Admin)” or press Windows + X and click “Command Prompt (Admin)”.

• Run diskpart command: Type diskpart in the Command Prompt and press Enter to open the DiskPart utility.

• List disk partitions: Type list disk and press Enter to list all available disks.

• Delete faulty partition: Type select disk (e.g., “select disk 1”) and press Enter to delete the faulty partition. Then, type create partition primary /s followed by the desired file system type (e.g., create partition primary ext32) and press Enter.

• Format partition: Type format fs=ntfs quick for NTFS or format fs=ext32 for FAT32 to format the newly created partitions.

Post-Recovery Steps

After attempting the above methods, you may need to perform additional steps to restore your system:

• Reinstall Windows from a different disk: If you successfully reinstalled Windows on another disk using Method 1.

• Apply System Restore: If you restored your system using Method 3.

• Run Disk Check (chkdsk) again: Type chkdsk /f and press Enter to run the check again.
