Windows 7: How to do a Windows 7 REPAIR install on a Toshiba Laptop?

How to do a Windows 7 REPAIR install on a Toshiba Laptop?

After having some problems with Windows update and no fixes working, I have decided to perform a repair install on my 64-bit Windows 7 computer. I have read the excellent article about doing repair installs on this site but it does not apply for me since I don't have a Windows 7 disc. My computer came preinstalled with windows 7 (it is a Toshiba laptop) and all I have are four DVDs created from within the computer upon its first startup to clean install windows. I was also prompted to create a fifth DVD that I labelled (don't remember wh˙ because I did it 2 years ago) "windows 7 repair disc (windows recovery environment).

That's all I have. How can I perform a REPAIR install in my situation??? What steps should I take??

- By the way I have not installed SP1, that's actually one of the updates that fails.
This thread shows my problem if you must know about it: Windows Update error when installing SP1 code 80070BC9

Since I have a Windows 7 disc (it's a modified iso that lets me choose what version to install, you know, with that little file modified) I have tried to do the repair install, but I got this;

Windows 7 Professional cannot be upgraded to Windows 7 Professional. You can choose to install a new copy of Windows 7 Professional instead, but this is different from an upgrade, and does not keep your files, settings, and programs. You’ll need to reinstall any programs using the original installation discs or files. To save your files before installing Windows, back them up to an external location such as a CD, DVD, or external hard drive. To install a new copy of Windows 7 Professional, click the Back button in the upper left-hand corner, and select “Custom (advanced)”.

What do I do now...?

Windows 7 Ultimate SP1 64-Bit

I'm confused.

In your first post you say you don't have a Windows DVD, only a set of recovery discs and a Windows startup repair disc, but in your second post you say you DO have a Windows disc.

This tutorial shows you how to carry out a repair install.

Actually Ive just found it, I have had it for about a year i think, i created it by burning an ISO that I had downloaded previously, and I found it would work. I did try the tutorial you link me to but I got the error that I've copy/pastied in my second post. Any ideas?

You have two threads going on this now. Find another Pro ISO w/o SP1 to try Repair Install. The all-versions DVD is probably at fault. That error is extremely rare.
