Dear Max G,
Thank you for reaching out to us regarding the boot issue you encountered. We understand how frustrating it can be when your system doesn’t start as expected, especially when you need it for work.
To help you resolve this, we’ve outlined the steps to upgrade Windows 11 from a USB drive while keeping your data:
- Prepare the Installation USB
- Download the Media Creation Tool from Microsoft:
https://www.microsoft.com/software-download/windows11
- Use the tool to create a bootable USB drive (formatted as FAT32, UEFI-compatible).
- Connect the NVMe Drive and Start the Upgrade
- Boot the PC from the USB → choose Repair your computer first.
- If repair fails, select Install Now and keep your data (choose the current Windows partition without formatting).
- During Installation
- If running setup from within Windows: select Keep personal files and apps to retain both applications and data.
- If running setup after booting from USB: options to keep data may be limited (usually only personal files, not apps).
- Complete the Upgrade
- Windows will reinstall the system, update the boot loader, and configure drivers for the current hardware.
- After completion, the NVMe drive should boot successfully on the machine where the upgrade was performed.
Thank you for your patience and cooperation.
