A social worker gave a disabled friend a Gateway M285-E tablet notebook without an operating system. The computer will boot from a Windows XP Pro (full version) cd up until you enter the partitioning information and then displays a "Setup cannot find a hard disk...". I have booted with a diagnostic disk - Spot Mau Powersuite and it won't transfer files. The HD is a Hitachi 80GB SATA confirmed both with BIOS and physical observation. I know the screen, DVD drive, screen mouse and button all work fine. I don't have an external enclosure to check the HD. Would it be best to just replace the HD, or buy the ext. enclosure and check the drive? Or can someone suggest software to reformat the drive or rebuild the MBR if that is necessary? The Windows sticker says it came with "Windows XP Tablet PC Edition" Will XP Pro be useable on that machine? I don't mind loosing some of the graphic features since my goal is to get basic funtionality for web surfing and word processing. I suspect this unit is from a school system and the HD was wiped before giving it away. How do I rebuild from that? Thanks!
