I have two hard drives on this computer. I used to dual boot Windows 8 and Windows 7, each separated by physical drive. Windows 8 was my primary OS. I recently re-installed Windows 7 (overriding the existing Windows 7 installation) and lost the OS choice prompt.

How do I boot to Windows 8? How can I edit the boot record and tell the machine to look for another OS or give me the option to choose when I start the computer?

there was already a similar question here How to use BCDEdit to dual boot Windows installations? , but your case is on reverse-direction.

Assuming that you're currently on windows 7 on drive C:, and windows 8 is on drive F:, then you can run both of these commands from cmd (as administrator):

  1. bcdboot f:\windows (this maps to Windows 8)
  2. bcdboot c:\windows (this re-maps to Windows 7)
