I bought a copy of Windows 7 off a vendor on eBay. I've been trying to install it for a week now. In the meantime, i think my machine has gotten infected. It has 3 hard drives in it. Two of them are infected, i think. I've disconnected all but one of them. I also bought a new one. I've tried installing over Windows XP SP3, XP SP2, and over a brand new drive with no OS on it. After that failed, I installed a new copy of Windows XP and tried to install Win7. Fail. Took that drive out and put in an older one, wiped the partition and tried to install Win7. Fail. Installed XP, then tried again. Got halfway through the installation process and the machine rebooted, and wouldn't go any farther, although it gave me the choice of restarting with a previous version of Windows. After trying several times to employ the option of resuming the installation (using both options of starting from the CDROM or the Hard Drive), it only went as far as a screen that said it was installing and then freezing. I think I've tried every way of installing it (both 64 and 32 bit versions). What is wrong? I'd love some advice...anecdotal, scholarly, or other. Thank you.
Do i have to be connected to the internet while installing?
Can you install on a Hard Drive that has no OS loaded?
