I recently reinstalled Windows 11 from a USB drive and chose the option to remove all files and folders. However, I didn't do a system reset beforehand. Am I safe to say all my data has been wiped?

For peace of mind, check if your BIOS has a secure wipe option. That'll clear everything completely, and there's no way to recover data after that.

Yes, if you formatted and deleted the partitions during the installation process, then everything is typically gone.

No, you really shouldn't worry if you've followed those steps. Just ensure you don't use the drive again until you're certain.

If you deleted all partitions during the Windows installation, then yes, your data is wiped and would typically be unrecoverable, especially if you're using an SSD. Just keep in mind that some data could still be recoverable until that space is overwritten.

Exactly! Just remember, when you select "delete" in Windows, it only marks that space as free to use. Until something else writes over it, there's a slim chance of recovery. If you're really worried, use a low-level format tool to ensure everything is gone.
