Then you are not typing the commands correctly. Proofread them closely.

Yes, you can download Partition Wizard CD, rightclick the ISO file to burn to CD using Windows Image Burner, then boot it to Resize Win7 partition from the right by about 50 gb.

Be sure to check first if WIn7 partition is marked Active, because if its not then that's why it won't repair. Click Modify>Set to Active then run the Repairs.

Are you sure you marked it active?

Ok two things. The new button in the windows instaillion screen is greyed out.
Will partition wizard make everything much simpler?? If so I might quickly run to parents shop.

Also I selected shrink it said shrunk by 439. Now what??

If same as surety max then I doubt it will work

You have to choose the unallocated space that you shrunk to create a New partition and Format it for install. It hasn't finished shrinking it yet.

It's going to shrink Win7 by way too much. So after you install, boot into the old Win7 partition to set it as Default and turn off its boot menu, reboot to test it boots into the old Win7 partition on its own now.

Next go into Disk Mgmt to Delete the rescue install you made, then I would immediately Extend the Win7 partition back into the space you shrunk: Partition or Volume - Extend

Did the shrink complete?

After the shrink completes it will appear as Unallocated Space. As I said before you need to highlight it, then choose Drive Options>New to create and format a New partition there in the Unallocated space.

Ok good news. I'm installing windows on that unallocated space. What do i do once it is done
My only concern is when it reboots durnig installion, how does it know how to get back into windows.

If for some reason the new install doesn't configure a Dual Boot, install EasyBCD (click Download - no Name or Email required) to add the old WIn7 to a Dual Boot menu on the Add OS Entry tab.

Then reboot into the old Win7, in Control Panel>System>Advanced System Settings>Startup set old Win7 as default OS with no boot menu, reboot to test that.

Then when it boots correctly confirm old Win7 is marked System Active in Disk Mgmt then delete the test install, Extend the old Win7 partition into the space you shrunk.

I'm going to bed.

Never touching windows 8 again.

Sorry for the pain and not listening. I wad stressed, in year 12 and assessment task was due tomorrow, and that was only PC in house. To make me even more stressed I was on the most slowest and smallest Android phone ever. It has 512mb of ram, and a 3.2 inch screen. So small!!

Sorry for the pain
