The first step is to prepare a USB flash drive with at least 8GB of free space and format it to the NTFS file system. Before starting, connect the USB drive to your computer. There are several ways to format it:
Option 1: Using File Explorer
Step 1. Press Windows + E to open File Explorer.
Step 2. Click This PC on the left panel and locate your connected USB drive on the right.
Step 3. Right-click the USB drive and select Format.
Step 4. In the Format window, choose NTFS from the File System dropdown and check Quick Format.
Step 5. Click Start to begin the process. If a warning appears, click OK to confirm.
Option 2: Using Disk Management
Step 1. Right-click the Windows icon on your desktop and select Disk Management.
Step 2. Locate your USB drive, right-click it, and choose Format.
Step 3. Select NTFS as the file system, check Perform a quick format, and click OK. Confirm any warning that appears.
Option 3: Using AOMEI Partition Assistant
Sometimes File Explorer or Disk Management may fail—for example, the Format option may be greyed out or Windows may show “unable to complete the format”.In such cases, AOMEI Partition Assistant is a reliable alternative.
This tool allows you to format disks or partitions quickly and also serves as a USB or SD card formatter. Notably, if your USB drive is currently formatted as FAT32, AOMEI Partition Assistantcan convert it to NTFS without losing data, allowing you to avoid a full format and retain your files.
Step 1. Install and run AOMEI Partition Assistant Professional. Right-click the drive you need to convert. Select “Advanced”> “Convert to NTFS”.
Step 2. In the pop-up window, NTFS is selected by default. Click “OK”.
Step 3. Now the USB drive is with NTFS file system. Click “Apply” to execute it.
Once your USB drive is formatted to NTFS, the next step is to load the OSU1 file onto it. Follow these steps:
Step 1. Download the latest version of the Xbox One console OS from the official source. The download may take some time, so be patient.
Step 2. Once the download is complete, extract the OSU1 files directly onto your USB drive, ensuring they are placed in the root directory for proper installation.
Step 1. Power off your Xbox One console, then plug in the USB drive containing the OSU1 files.
Step 2. Press and hold the Bind and Eject buttons, then press the Xbox button on the console.
Step 3. Release all buttons when you hear two power-up tones.
Step 4. The Startup Troubleshooter screen will appear. Select Offline system update by pressing X on your controller.
Step 5. A message saying “Preparing console…” will appear. The update time depends on your USB drive’s read/write speed and may take 15 to 45 minutes.
Step 6. Once the process completes, the console will restart automatically. Wait patiently until the Xbox One is fully ready to boot.
Resetting your Xbox console is another effective way to resolve the system error E102. You can perform this reset using the Xbox Startup Troubleshooter by following these steps:

Step 1. Press the Xbox button on your controller to open the guide.
Step 2. Go to Settings > System > Console Info.
