There should be a recovery partition, unless you replaced the hard drive. Have you tried power off the laptop, holding down 0 and then turning it back on? If there is indeed no recovery partition, get in touch with Toshiba and they should send you the recovery disks for free.
Unfortunately, it's a 2005 model & they hadn't yet started using recovery partitions. Toshiba discontinued support & software for this model & suggested that I buy a new retail version of xp. I paid $2600 for this thing in 2005. I'm not putting another dime into it. I'll wait until I can find someone willing to burn me a copy of their OEM disks.
