I let someone use my computer and somehow they ended up formatting my hard drive, so now I have no operating system. If windows are not coming how can I fix.

I let someone use my computer and somehow they formatted my computer, s he always tells me to run the Startup Repair, but it won't let me. Someone knows how to fix this?

Your best option is to try to reinstall Windows 7:

If Windows 7 is pre-installed:

New computers that come pre-installed with Windows often have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

If your recovery partition is not available or damaged, you must contact the manufacturer of your computer, and request that a defined recovery disk you can use to reinstall Windows 7. They could practice a small shipping and handling.
------------------------------------
This is how the recovery partition is accessible to most popular brands...
For Dell, press CTRL + F11 directly after switching on the device
For HP, press F11 directly after switching on the device
For LG, press F11 directly after switching on the device
For Toshiba, press and hold "0" BEFORE and during the power upward
For Acer, press and hold ALT + F10, as soon as you see the logo
For Asus, press F9, as soon as you see the Asus logo.
For Samsung, press F4 to the power upward...
For Fujitsu, press the F8 key directly after the power
Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"
Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".

If you have a retail copy of Windows 7 installed, use your reinstallation disk to perform a new installation:
