This is a follow up to my last question

http://www.tomshardware.com/forum/383952-31-video-signa...

Basically I had to stop in trying to fix that problem because I found that Windows wouldn't boot. It said I needed to insert the disk and repair the install, however I didn't have it anymore. I had to hunt another up and buy it.

Now I have booted from the disk and tried to repair the install twice. The first time it just didn't work, the second time it said this is a problem that cannot be fixed by the automatic repair.

I am running Windows Vista Ultimate 64bit OEM.

What I am wondering is, is there any way to get the system to boot again without losing all my files? Do I have to add a new hard drive and install Windows to that? What about upgrading to Windows 7 Ultimate? Can I reinstall Windows Vista Ultimate without losing all my programs? Will reinstalling Windows even work?

If you changed your motherboard that's why, windows saves onto your motherboard in a way, you will need a new copy of windows for it to boot once more.

"I had to hunt another up and buy it."

Does this mean you purchased a new copy of Windows? You should be able to do a clean install - this will wipe out all your data and applications.

You need a new copy of windows. With a new CD key.

Would I be able to install it without losing my stuff then? Can I do an upgrade install without actually being able to boot windows?

No, you have to do a fresh install. Make a partition on the HDD for the new install. The old files will be accessible but all programs and apps will need to be reinstalled.

I see. Would I be able to request a new product key from windows even though I used the OEM version? Or is my only choice to buy the new Windows?

As for a new partition, how would I go about making one? Don't know how to without being able to boot, but I certainly have the space.

Microsoft might give you a new key. They will deactivate the old key though, if they give you a new one. You create the partition on the drive when you install windows. Just partition off the old files. (is they are 89gb then give them a 90gb partition). Install windows on the new empty partition.

I only see the option to install to the drive or format the drive when installing windows. How exactly do you create a new partition? Don't want to accidentally destroy my old files.

I don't think it is a product key issue. I swapped out the motherboard and windows booted fine although I initially had some driver problems.

Later it prompted for activation but I tried online and it worked.

Sounds like a major driver issue. Probably need to reinstall fresh.

That is NOT true. There is a way to fix the issue without having to reinstall Windows. Check this link: http://www.dowdandassociates.com/content/howto-repair-w...
