Lost My Windows 7. After Installing Kali Linux Rolling.

Hi Sir(s)/Maam(s). Can you pls help me? So i tried to install a Kali Linux rolling in my HP Probook Laptop pre-installed with a Windows 7 ultimate 32bit. I googled the machine of my laptop and it says it can support 64 bit. Then i followed instructions on how to (dual boot) Kali Linux with Windows 7. so i followed the instructions only that since the instructions written in the website: You are being redirected... showed a portion Using a tool "Gparted". This did not show up while i opened "Kali Live"(as in the instructions), and i thought to myself maybe it ddnt show an option - "gparted" bcause the kali they were using to install is an old kali while i'm installing a new 2016.1 kali rolling 64bit. so i went ahead and clicked graphical install. so the installation went on(Kali Linux) to an option where it says - Partition Disk(so my thoughts were correct i thought) then i went to a partition where it said "Separate/home partition" so i thought maybe it'll separate my windows 7 partition automatically. then it displayed the partitions it made so i thought maybe i was doing everything right.(as shown here You are being redirected...). And then installation was complete and it requested to reboot so i went and rebooted it. now i was expecting to show options where i can choose where to reboot Kali Linux or Windows 7. Now it only shows Kali Linux. . Did i delete my windows? i had so much important data there... Can someone ls help me? P.S. I'm a newbee. i'm a gradute of AB History(just saying) so i have very little knowledge about computers. but i'm a quick learn, at least i'm trying to be... i really need help. right now i wanna die.

First thing I would do is to open a file manger and see if you did delete or overwrite your Windows partition and if it is still there all you have to do is update your MBR.

If it is gone then you could try to recover your files in Kali and save them to another drive.

Good thing your a quick leaner, Oh and don't skip any steps this time.

Don't you have a backup of your important data?
Unfortunately, you may had erased your disk when you installed Kali.
But also it can be that you installed Kali on a created partition and your Windows is still there, you just can't boot.
Boot Kali and on a disk manager look for a partition formatted as NTFS.
Return here with what you have fond.

Thank u for replying to my post. So i've been reading about how to see where my files were inside linux, and using the windows cd. So i followed the procedure in "repair my computer" where it made me use the "bootrec.exe" command in the command prompt. But it did not detect any installed windows os. So u assumed i deleted the windows partition when i installed kali. :'( so i re-installed windows again, fresh, reformatted thw drive and now i'm just downloading every drivers i can find
