Installing Windows 7 on the second drive

Hi, I hope someone will be able to help me...
I have two pc's and on one of them windows xp was crashed and computer did want to start. so i took the hard drive out and plug it into my other computer (vista) and installed windows 7 into the other hard drive. but now when i plug it back to the right pc it still does not want to start (black screen) and on mine i have to options if windows (vista and w7), obviously if i choose w7 error comes up and if vista works fine... any ideas what can i do?

 

Tried that, but for some reason cant boot it from the dvd, thats why decided to take the hard drive out and do it from the another pc...

 

It is, but still no luck... Is it possible that the actual win dvd is not bootable?

 

how can i upgrade my BIOS?

 

You need to make a DVD, or USB drive, bootable with the contents of your Windows source files. Copy the content of your Windows DVD onto your healthy PC's hard drive. I suggest using a new folder on the desktop for easy access, since you won't be needing it again except for this purpose.

Then use whatever DVD burning software you have, and burn the contents (without the folder) to a DVD. If you have none, recent versions of Windows can do it, too. You can also use ISO's, which is my preference, but that's me.

Is your DVD a genuine Windows 7 disc from your computer manufacturer or an upgrade or full edition disc from Microsoft? They should all be bootable.

As for updating the BIOS, that's never a bad idea, but it can be potentially dangerous, if you don't know what you're doing. You would need to download the latest version of the BIOS from your computer manufacturer, and then follow the instructions and make a bootable disc out of what you download (lol...again with that.). If you build your own systems, you'd need to get this from your motherboard/system board maker. This you can do on your machine that works fine. Some BIOS versions will allow for you to update it from within Windows, but since you can't get anything to boot on your machine that you want to install Windows on, you will just have to burn it on a CD or DVD (CD is good enough). I'm not sure why would need to update the BIOS for the purpose of making a bootable DVD, though...?

Who makes the machine that you're having trouble with?
