ubuntu - After Boot Repair, Windows 7 does not boot

After I purchased my computer I followed these steps:

1. Installed Windows 7.


2. Installed Ubuntu.


3. There was no boot option, and Ubuntu automatically boots, leaving me no option to boot Windows.


4. I used Windows Repair to repair the MBR or whatever it is.


5. Now Ubuntu doesn't boot, and there is no option to boot Ubuntu.


6. Finally I used Boot Repair Disk.


7. Now there are options for Windows and Ubuntu.


8. Ubuntu boots properly.


9. Windows boots, but there is a blank purple screen after that.

Here is the link of my system boot information: http://paste.ubuntu.com/12095051
