Dual Boot Windows 7 and Linux Mint 13, Windows failed

By trying to dual boot Linux Mint 13 and Windows 7 I have made some changes in the partitions on my hard disk. I succeed and Linux is working fine but now I can't start windows. I tried to run the recovery and set my computer back to factory settings but I can't find it either. Is there anyone with an idea how to solve this?
I'm new to this site so I'm also not quit sure if this is the right place for this question, any help is welcome! Doesn't matter how smal.

Well, Win7 takes three primary partitions when it's installed -- and you can't mess with them without causing yourself a lot of grief. If you want to install Linux alongside Win7 you can only use logical partitions for the Linux side of the world; e.g., root, swap, home, etc. And, of course, you would have to shrink the Win7 side to give yourself a large block of disk space to logically partition and install Linux.

So, if you had an already installed Win7 and fiddled with any of the existing Win7 partitions... uh, you probably blew it and you'll need to reinstall Windows from scratch (then wait through over 250 critical updates, oh, joy). I don't remember what the names of any of them are (because I wipe Win7 completely, install Linux and then, maybe, install Win7 in VirtualBox; save a whole lot of time and trouble) but somebody with a "real" Win7 machine might be able to tell you (won't do you much good if they're gone, though).

Now that I think about it, maybe that would be a good alternative, if the thing is all messed anyway, to do a complete rebuild -- partition you drive completely with a, oh, I don't know, 50G - 100G partition for Win7, install VirtualBox (pointing it at that partition) and do a full install of Win7 as a virtual machine? Otherwise you're probably going to have to start from scratch and reinstall Win7. This because you're not able to use any of the Win7 "fixit" tools which is a good indication that the tools can't find what is needed to get everything back -- you do want to install Win7 then install Linux after it (just be aware of those three primary partitions that Win7 will create and remember that you will use logical partitions for Linux, you can look at the drive with cfdisk to see what they are if you're curious).

There might some way to fix it without reinstalling but I don't know what that might be; essentially, I won't all Windows on the property and only maintain one copy in VirtualBox. Hopefully you didn't blow it beyond recovery (somehow or other).

Hope this helps some.

You would have to post some information on what your drive/partition structure is as we have no way of knowing what changes you made.
Are you still able to boot Mint? If so do it, otherwise boot the Mint installation disk and open a terminal and run this command:

sudo fdisk -l
Lower case Letter L in the command. If you run it from the installed Mint, you will be prompted for your password.
Posting that information should enable someone to tell you whether you still have your windows partition.

To find Grub (from the German wiki
sudo fdisk -l 2>/dev/null | egrep "Disk /|/dev/" | sed "s#^/dev/#Part /dev/#" | awk '{print $2}' | sed 's/://' | xargs -n1 -IX sudo sh -c "hexdump -v -s 0x80 -n  2 -e '2/1 \"%x\" \"\\n\"' X | xargs -n1 -IY sh -c \"case  \"Y\" in '48b4') echo X: GRUB 2 v1.96 ;; 'aa75' | '5272') echo X: GRUB Legacy ;; '7c3c') echo X: GRUB 2 v1.97 oder v1.98 ;; '020') echo X: GRUB 2 v1.99 ;; *) echo X: Kein GRUB Y ;; esac\""
Copy and paste the entire command into a Terminal / Konsole.
E.g.: Kein Grub = no Grub, especially 6f74 = fat 32.
