Windows Installation Stuck at 0%? Here’s What Actually Fixed It

Why Windows Installation Gets Stuck

Few things are more frustrating than watching a Windows installation freeze at 0% or 1% for hours. You’re excited to get your new system running, but instead, you’re staring at a progress bar that refuses to move. This is a surprisingly common issue with several possible causes.

Common Causes of Stuck Windows Installation

• USB drive issues — Corrupted installation media or slow USB 2.0 ports
• Hard drive problems — Bad sectors or incompatible drive formats
• BIOS/UEFI settings — Incorrect boot mode or secure boot conflicts
• Hardware conflicts — Incompatible RAM, peripherals, or drivers
• Corrupted Windows ISO — Downloaded file is incomplete or damaged

Fix 1: Disconnect All Unnecessary Peripherals

This simple fix worked for me immediately:

1. Unplug all USB devices except keyboard and mouse
2. Remove external hard drives, printers, webcams, and USB hubs
3. Disconnect any secondary monitors
4. Restart the installation

Sometimes a single incompatible device can halt the entire installation process.

Fix 2: Use a Different USB Port (USB 2.0 Preferred)

USB 3.0 ports can sometimes cause issues during installation:

1. Remove the installation USB drive
2. Plug it into a USB 2.0 port (usually black, not blue)
3. Restart the installation

USB 2.0 is slower but more compatible during Windows setup.

Fix 3: Recreate the Installation Media

A corrupted USB drive or ISO file is a common culprit:

1. Download the Windows Media Creation Tool from Microsoft’s official site
2. Use a different USB drive (at least 8GB)
3. Format the USB as FAT32 (not NTFS) for better compatibility
4. Create the installation media again
5. Try the installation with the new USB

Fix 4: Change BIOS/UEFI Settings

Incorrect BIOS settings can prevent Windows from installing:

Disable Secure Boot

1. Restart your computer and press F2, F10, F12, or Delete to enter BIOS
2. Find Secure Boot (usually under Security or Boot tab)
3. Set it to Disabled
4. Save and exit

Switch Boot Mode

1. In BIOS, find Boot Mode or Boot List Option
2. If it’s set to UEFI, try switching to Legacy (or vice versa)
3. Save and restart

Fix 5: Check and Prepare Your Hard Drive

Hard drive issues can stop installation cold:

Delete All Partitions

1. Boot from the Windows installation USB
2. When you reach “Where do you want to install Windows?”, select each partition
3. Click Delete for each one
4. Select the unallocated space and click Next
5. Windows will create the necessary partitions automatically

Run Diskpart to Clean the Drive

1. At the Windows setup screen, press Shift + F10 to open Command Prompt
2. Type diskpart and press Enter
3. Type list disk to see all drives
4. Type select disk X (replace X with your drive number)
5. Type clean to wipe the drive completely
6. Type exit and restart the installation

Warning: This erases everything on the drive!

Fix 6: Test Your RAM

Faulty RAM can cause installation failures:

1. If you have multiple RAM sticks, remove all but one
2. Try the installation with just one stick
3. If it still fails, try a different stick
4. This helps identify bad RAM

Fix 7: Update Your BIOS

An outdated BIOS can cause compatibility issues:

1. Visit your motherboard manufacturer’s website
2. Download the latest BIOS update
3. Follow their instructions to update (usually via USB)
4. Try the Windows installation again

Fix 8: Try a Different Installation Method

If USB installation fails, try:

• DVD installation — Burn the ISO to a DVD and install from there
• Network installation — Use PXE boot if your network supports it
• Internal hard drive — Copy the ISO to a separate partition and boot from there

Conclusion

In my case, the installation was stuck because of a USB 3.0 port conflict. Switching to a USB 2.0 port and disconnecting all peripherals allowed the installation to proceed smoothly. If you’re still stuck, try recreating the installation media and cleaning your hard drive with diskpart. These methods solve 90% of stuck installation issues.
