Create a Windows 7 boot/repair disk

Contact Toshiba and get Recovery/Restoration media.  That really is your BEST option.

Yes - you could download the ISO image of the Windows 7 Home Premium media, use a tool to create a bootable DVD or USB stick, install using that... but you'd need to come up with the drivers and other software and so on (it would be a cleaner installation in many cases, but more complicated for anyone not into such work.)

... but that's completely up to you.

Hi,

Are you able to load Windows?  If yes, Start > Type Recovery

This will take you to the Recovery Media Creator and you can create your own disk.

You can run the Toshiba Recovery program by turning on your system and holding down the '0' (zero) key.  This will start the recovery program, and let you return your computer to its out-of-the-box-state.  If your Toshiba Recovery partition is not intact, and you did not make a set of Toshiba recovery DVD disks, then you can order them:  Cost is minimal (approx. $20 USD)

Ordering Recovery Disks

These disks will have the drivers and pre-installed software that came on your disks.
