1. Slave Hard Drive. Pull the hard drive out of the Toshiba laptop and hook it up as a "second" hard drive to a desktop computer. (As a slave - you do not want to boot this drive). You may need to purchase an interface adaptor to do this. Also, if you're working with IDE drives; you may have to adjust "jumper" settings. Best to use one of the internal interfaces of the "other" computer rather than an external "USB" connection.
2. Recovery Console. The default state for a Windows XP Home Edition system is no password set for Administrator" account. Unless you explicitly set a password for this account, just hit <Enter> key when it is requested.
So... You ran Recovery Console and did commands, "fixboot", "fixmbr", and "chkdsk /p /r".
a. Does that mean you successfully booted from CD, selected option to "repair" a Windows installation, selected the desired Windows installation, successfully responded to the prompt for Administrator password (which you successfully entered?), and then successfully executed all of those commands?
b. And now it requests an Administrator "password" that you don't know?
c. Did the "chkdsk" commands report and/or "fix" any errors?
d. Did any of the commands report any warnings and/or errors?
3. Windows XP Install CD. If you're thinking of reinstalling the operating system, you'll need compatible installation media. A Windows XP Home Edition "product key" will require a Home Edition install CD. Try to get SP3. A "repair" install will revert your system files back to the version of the source CD. Look for a "product key" sticker on the bottom of the laptop or possibly under the battery. Not sure, but I don't believe OEM and Retail versions of the CD accept each others' keys.
