Need Help, grub rescue

So the title pretty much says everthing, after installing another OS using unetbootin I created a partition for the secondary OS, it didn't work so I deleted the partition with Minitool Partition Wizard not knowing I deleted the bootmenu for unetbooting, now I get this error and want to know how to load up the original boot system(windows 7 bootmenu). I saw a few but most say that I need a upgrade/installation disc which I don't have, so if you can help me with this problem please tell me how.

Error: no such partition.
grub rescue>


Specs:
Windows 7 Home Premium
Dell Inspiron
1TB Hard drive

! You have to activate your C partition with Partition Wizard CD
2. Download and burn the exact Win 7 edition (same as your system) to CD
3. Run startup/repair 3 times - Startup Repair

WHS, So I need to download Windows 7 Home Premium from the link you sent me?

If Home Premium SP1 is the system you want to fix, then yes.

I dont know if thi is going to work,but im going to install another OS again (Kali Lunix) and going to try to replace it with the new boot menu kali lunix is going to give me to see if it works, the only thing im afraid of is it said to split a partition for kali, since i dont have access to windows 7 im going to need to resize the windows 7 partition which may delete everything

I think I understand what you are trying to do - install another Grub in the hopes it will pick up the Windows bootmgr. I am not sure whether that will work.

And be careful with the creation of new partitions. Check first how many primary partitions you already have. If it is more than 3, you cannot create another partition - at least not without running into the dreaded dynamics.

Better check first how the disk is subdivided - with the Partition Wizard CD (the .iso is in the last box of the webpage)

You only have to rewrite the MBR boot code. Partition Wizard has an option "Rewrite MBR". Or win7 repair disc: bootrec/fixmbr. Or bootsect /nt60 C: /force /mbr
