Alright, I found some information pertaining to use of the recovery partition. It's far too long to post here, so I'll ask you to download the instructions from Toshiba.
1. Visit the
Toshiba Support Website.
2. Press, "Product Support."
3. Click on, "Laptops," then click, "Satellite," then type, "A135-S2276" into the Model Finding Filter.
4. Click on your model and press GO.
5. Click on the second User's Guide link.
6. If the option is available, download the guide. Otherwise, scroll to page 58.
To ensure you're looking at the right page, this is a small piece of the page:
Getting Started
Hard Drive Recovery Utilities
Hard Disk Drive Recovery using the recovery partition
You have the options of recovering your system using the Hard
Drive Recovery partition to the factory-set default....
CAUTION: If you decide to use this method, all files that were saved to your computer since you bought it will be LOST! I only recommend this method if the files on your system are of no importance to you or if you have backed them up to some form of removable media (CD, DVD, Flash Drive, External Hard-Drive, etc...).
I'm posting this as a solution so that the link I posted will actually work. However, if this doesn't solve your problem, we can continue debugging the situation just as easily as before.
Let us know how things turn out.
