Can I run a Windows 7 repair disk that was created on a different PC?

I have an issue with my desktop PC.
I believe I have a corrupted system file since the HDD is no longer bootable; however I have been able to remove the infected drive and install it as a slave on my HTPC. This has allowed me to backup all my important files.

My question... I'd like to run a Repair on the existing Windows 7 install but I never created a rescue disk when the OS was operational. Can I create a repair disk using my Windows 7 OS off the HTPC and run it over my desktop PC? Or is the disk specific to the PC the OS belongs to.

I'd like to avoid a fresh reinstall if possible.

As long as they are both x64 or both x86, which ever you have,

Have a look at the red box at the top of this tutorial,

Click to expand...

...they are the same Windows 7 x64 versions.

You should be fine then.

So now I have a new issue.
The recovery seems to be hanging at the System Recovery Options "Searching for Windows installations..." screen..
The status bar scrolls and scrolls but ultimately does not get past this point of the recovery process.

Try the bootrec commands given in Troubleshooting Windows 7 Failure to Start.

This can jumpstart the appearance of an installation to repair when it fails to do so.

Everything else that can be done to start Win7 is in the tutorial. Is this your problem?
