Okay, I am pretty knowledgeable with computers... but with windows 7 I do not understand part of the installation procedure. Here is what I would like to understand: Upon installing Win7 it seems to put the boot sector, or boot file... whatever it is called on a different hard drive. So here is what happened to me. I installed Win7 with other hard drive in my computer. I installed it on a new HDD and later on down the road I took out a different HDD that I had in there during installation. Well, my OS failed to boot. Why does it put this here? Is there a way to move this over? Is there a way to change the boot device/sector/file/partition.. whatever? I tried just copying over some of the boot files... but my guess is that this is still pointing to a different HDD and still failed to boot. I realize I could put the Win7 CD in and probably do a repair but I would like to know an alternative method on this. If anyone can point me in the right direction or even tell me what to google to begin researching this, or to find some tools for changing the boot sector, I would appreciate any assistance.
