If you rooted your android then messed up stuff, now you wanna go back to day it was working, hey you find yourself in deep shit, so here is what you do.
Vista and Win7 cannot see the hard drive on Toshiba laptops. You can use a USB stick or Toshiba's external floppy drive to load the RAID driver.
This procedure is helpful for a dual-boot scenario, where the Toshiba XP load is the first partition.
For example, you have a netbook or desktop that you want to install Windows 7 onto, but can’t use DVD or USB for whatever reason (or don't want to, like me). This method will allow you to boot and install Windows directly from the hard drive. This guide involves plugging the hard drive into another working computer, preparing the hard drive, placing it back in the system, and installing Windows as usual.
This guide will work for Windows 7 and Windows 8. I have a Windows 8 instructable, but it's essentially the same guide with some Windows 8 pictures. This guide will not work for Windows Vista - I have an instructable for that.
