Create Windows System Repair Disk

When windows won't boot or you are caught in a "windows shut down incorrectly" loop, you will need a Windows 7 install disk or Windows 7 repair disk. Chances are good you can't find your install disk if you ever had one so creating a repair disk may be your only option. I think this is 32/64 bit specific so you need to use a matching windows machine. Start Menu and right click/properties on "computer" will tell you if your Windows is 32/64. On the non-booting machine, if it has 4GB RAM or more it is probably 64 bit.

To make the repair disk go to Start Menu and type "system repair disk" and the option should pop up. Burn the disk and use it. You need to be able to boot from the CD. If your system does not automatically boot from the CD (it probably will), try to bring up the boot menu by pressing the boot menu key. This varies by motherboard BIOS but some possibilities are "esc", F10, F12, F2. The bottom of the screen during boot should tell you but it may go by fast and make reading difficult.

I guess I should mention how if nothing brings up the boot menu you will need to enter the BIOS setup and change the boot order so the CD is listed first.

If you need to make an ISO do this:

Well, I know the others are trying to help but I am pretty sure none of these answers solved it because I was with the same problem as you. So here was what I found:

Steps:

1 - Open your temp folder through: Start + Run (type on the search programs and files box "run", or shortcut windows+d) + type %temp% on the Run box (it will open your temp folder);

2 - Go to the system repair disc tool (Yes, I know there is no disc on the drive): Start / All Programs / Maintenance / Create a System Repair Disc

3 - Once you click to create a disc you are going to receive a message "System repair disc could not be created. There is no media in the device.". It's ok, continue closing ONLY this message, the Create a system repair disc windows MUST still be open.

4 - Now you can see at the temp folder, you have a new file called "somesortofbignumber.iso" around 100 or 200 MB (if you can't see it press F5 to refresh the folder). But still, you can't move, or copy, or anything the file because the system says it is in use. That is your ISO file, you just can't do anything with it yet. So, in this part you have to use a program that lets you manage these kind of files. I used one called Unlocker.

5 - After you installed Unlocker the only thing you have to do is: Right click "somesortofbignumber.iso" + select Unlocker + select the option "Copy" and the destination folder (remember if you want to rename the file don't forget the ".iso" ending).

After that you can search for a USB tool solution from a ISO file.

It worked very well for me, good luck.
