My s230u fell. From what I can tell, the notebook is okay, but the disk is shot. If I try to boot, it fails. Tried to repair bad sectors from for BIOS. The check found bad sectors, but was unable to repair. I took the drive out and connected to a different pc via a USB adapter and was able to recover some files. For some of them the drive would make a clicking sound and fail. I think I need a new HDd, which I can buy. How can I reinstall windows now? There was no media that came with the notebook.
