Just barrow a Windows 7 Installation Disk, can be Upgrade, OEM, or full. Only stipulation is it must be the same version, ie if ultimate, then barrow a ultimate ver.
With OEM, or full version. do the install, But do not enter the Key during the install, wait untill after windows is installed.
With the upgrade version, you must first select custom instal to do a clean install. Again do NOT enter a key untill Install is complet - BUT must do two things first, a simple registy edit, and run a dos Cmd.
In Both the cases above, You USE the Key that is for YOUR laptop, NOT the key for the "barrowed" Disk
Once install is complet, vist the toshibia support for the drivers and or any software that is need. Just download and install. (I do this Before entering the Key and activating.).
Compliments of MaxiumPC on using Upgrade version for a clean install.
A true geek has never been intimidated by the registry, but lets face it, it's a mess in there. To access the registry you will first need to open up the start menu and type "regedit" into the search field, followed by enter. To find the proverbial needle in this haystack, you will need to navigate through the tabs listed on the left in the following order:
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/ . If you don't like doing it the hard way just click Edit then Find and type MediaBootInstall into the search field, and press enter.
Once found, double click MediaBootInstall and change the "1" to a "0". Once you have finished this, simply click Ok and close out the Registry Editor.
AND THEN
Before we try to activate our copy of Windows, we need to reset or "Re-Arm" the activation sequence. To do this, simply open up the start menu and type cmd but instead of just pressing enter, you need to press "Ctrl" + "Shift" + "Enter" to run it as an administrator. You can also accomplish this by clicking the start menu, typing cmd into the search box, then right clicking the command prompt application and selecting Run as administrator.
Once the command prompt appears type slmgr /rearm and press enter. Next simply type Exit and hit enter again, after which it will ask you to restart your machine.
OR you may be able to just purchase the Toshibia Installation disk from Toshibia at REDUSE cost. - YOU alread paid for the Lic, you just need the disk. The disk is a dollar two-ninty-eight. They will OVER Charge, but shouldn't be over $15.
LOL - "dollar two-ninty-eight" for individuals born after 1960 - Old saying that Meant CHEAP.
