Windows 7: A disk read error has occurred, - after deleting partition

A disk read error has occurred, - after deleting partition

Hi,
I'm new to the forums and have decided to post so I can hopefully resolve the mess I have got my girlfriends laptop into....

1. The laptop already had windows 7 on it but I wanted a clean install so I created a W7 disk from an ISO on a usb stick.

2. It wouldn't however install onto the original partition as it froze during installation so I created another partition and installed W7 on there.

3.I then set the new partition as active and ran startup repair multiple times to allow the correct boot files to be installed onto the new partition

4.I then used command prompt to delete the old boot partition that had the old W7 on it, but then the laptop gave me the "A disk read error occurred" spiel

5.I have tried every command to rebuild my bcd in command prompt from the W7 disk but it still says no installations are found after the /rebuildbcd command

Specs:
W7 64 bit
Toshiba Sattelite C660
4GB Ram

Thanks for reading and replying in advanced, any help would be greatly appreciated.

Does the new win7 partition boot succesfully? Does it have a bootmenu with 2 options (new win7, old win7)?
Please post full screen image of diskmanagement with all fields visible. Please tell on which partition old win7 is and on which partition new win7

Thanks for the reply,

No it does not boot at all. All i get is black screen saying Disk Error. I did before get two options to pick Windows 7 at startup just after bios loading screen. I have completely deleted the old partition it is just unallocated space now, I cant get into disk management because the laptop will not boot.

Point 5 is normal! the OS is already in bootmenu.

Did you reboot after doing point 3? and system booted fine then?

Yes. After step 3 everything was fine but then I deleted boot partition in command prompt on the W7 disk and then it gave me the error.

If you boot into Recovery Environment... does it see the win7 installation?
How many partitions are on disk?

"command prompt" in win7 recovery environment:
Code:
 
diskpart
select disk 0
list part  (now you see how many partitions and the numbers)
sel part 0
det part
sel par 1
det part
sel par 2
det par
sel par 3
det par
exit
all partitions are healthy?

diskpart
list vol
exit

All are Healthy, for reference the C partition "New" is the created partition with W7 installed on it.

Also the second screen shot is of my system recovery screen
