Re: Trying to Recover Windows 7 for dual boot
You said you used the Windows partition as swap -- which implies you reformatted it.
In some cases, preinstalled Win7 machines come with two different partitions (at least). One contains the boot loader files, the other (much larger), the OS.
IF you only overwrote the bootloader partition, you could then reformat that and use boot-repair to get the Win7 boot files back.
But ... if you overwrote the Win7 OS partition, that stuff is gone. There are Win7 data recovery apps that might be able to allow you to get some files back, but you would have to remove your drive and connect it to a Win7 PC to do that.
Ubuntu 14.04, Mint 17; MS Win 8.1.
