When I opened my computer after shutting down it won't boot

Boot into System Recovery Options on Win7 installation media or System Repair Disk,

Open Command Line to Mark the 100mb System Reserved partition (preferred if you have it) or Win7 partition Partition Active,

run Startup Repair - Run 3 Separate Timesuntil Win7 starts.

Report back results, or if this succeeds then Post back a screenshot of Disk Management - Post a Screen Capture Image

You'll need to Download the ZIP file from the Download Tab, Find the ISO file. If you have a Flash Drive, You can use It and Make it bootable.

   Note

to make your Flash Drive Bootable, You'll need a Program called Rufus.

   Warning

Making your flash drive bootable Will Format ALL data on the drive!

But, There are ways of making your flash drive bootable WITHOUT formatting, there is another Program called EasyBCD that allows You to make your flash drive bootable!

I made a bootable usb stick with hirens bootcd, what should I do now? what kind of program I need to use?

Hello? Have you performed the steps I gave you yet?

After making my partition active and restarting the computer, boot menu don't show my usb stick anymore, it doesn't work. And the computer still gives me a black screen.

Did you use this flash stick to mark the Partition Active?

Which key are you using to trigger the stick? Try the Lenovo OneKey small button near the Power button to bet a Boot menu. Otherwise use F1 or F2 to boot into BIOS setup to set the stick first device to boot.

Try another USB port.

Try a DVD to make a Win7 disk for your version from Step 6 of Troubleshooting Windows 7 Failure to Boot or a CD to burn a System Repair Disk
from any Win7 PC.

I made a flash stick as a "repair disc". Do trigger the stick I press F12 and select the flash stick from the list. Also I tried another USB port and another computer it just doesn't work.

Not ever seen it be reliable as flash. Try CD, the Win7 DVD, or the ISO for your licensed version Win7 Home Premium x64 SP1 English Official ISO download written to stick with Windows 7 USB/DVD Download Tool

I downloaded that and put it on a flash stick still the same thing.

How did you put it on flash stick? Try writing it again with Download tool.

Check in BIOS setup that USB is enabled. Do you have a UEFI BIOS? If so the stick must be written with UEFI Bootable USB Flash Drive - Create in Windows

What about disks?
