Windows 7: How to reformat and reninstall Windows 7 Home Premium WITHOUT disk?

My laptop didn't come with an OS disk. I have 56GB out of 250, and honestly I don't know where it all went. Is there any way to reinstall without a disk? I'm not too big into torrenting things like this, but if its the only way I guess I would have to.

There is most likely a way, depending on what laptop you have.

Please fill in your system specifcations so we know what hardware you have.

But---why do you want to reinstall?

Is the machine running smoothly?

If the only problem is lack of drive space, I'd certainly do something else---get more drive space, find out what is using up your current hard drive, uninstall unnecessary applications, etc.

No. It's not smooth at all. I have a Toshiba Satellite if that helps. The only 2 programs I need on it are World of Warcraft and Google Chrome. Now that I think of it, I'm pretty sure that might be something in MyToshiba.

Back up your files, make your Recovery Disks to have as a backup and then run Toshiba HDD Recovery Utility to restore to Factory Condition, although this will include all the preinstalled factory bloatware and useless factory utilities which have better versions built into Windows 7.

If you want a cleaner reinstall borrow or find a Windows 7 installer ISO, burn to DVD or write to flash stick with Windows 7 USB-DVD Download Tool . If you download get a safe copy by googling Official Windows 7 ISO at My Digital Life (not a torrent).

Follow these steps to get a Perfect Reinstall of factory OEM.
