I tried to install the OpenSUSE Linux system on Windows 7 (x64) as a dual-system. The eventual purpose was to install Oracle for a Unix-system. It was an interesting journey, but unsuccessful, unfortunately.
Step 1: The installation of OpenSUSE was almost perfect
I downloaded OPENSUSE 13.1(x64) from http://software.opensuse.org/131/en and burned it to a DVD
I followed this link (in Chinese) for installation
Almost perfect except for the last step on automatic configuration. It hang here for several hours for the process. I closed the program and tried to install it again, the same problem. I decided to abort the automatic configuration.
But, but, but I have the OpenSUSE system running as a dual-system. Checked inside, it appears that most of the functionality works great. The only major problem is that I have to log into the system with the super user root account. The non-system account I created int the installation process is not even shown in the user account. I suspect the issue is related to the failed auto configuration process.
So the next step, obviously, was to install Oracle on OpenSUSE. Unfortunately, I found out that OpenSUSE is not a supported distribution for Oracle.

Note: OpenSUSE is different from SUSE. See this page for more information.
OK, then, I need to uninstall OPENSUSE 13.1. Sounds like a simple operation, right? Actually, not that easy as it has to deal with the partitions.
Step 2 - Uninstall OpenSUSE 13.1 and make the laptop back to the state it was
I found this video helpful.
So I download and install EasyBCD as suggested. Then I deleted the three partitions for the OpenSUSE installation. Restarting....
No bootable device insert boot disc and press any key...
Oh, No! The Master Boot Record messed up. Eventually I found this article helpful (fortunately, I have the Windows 7 installation CD).
Initially, I tried the first option 'Startup Repair'. But it did not work as it displays the D drive as where the window system resides. It is not right. The C drive is where Windows is installed. D is a logical drive for application (the three logical partitions for OpenSUSE have been integrated back to the D drive) .
Then, I used the command prompt method as suggested. Restart....
Bootmgr is missing. Press Ctrl+Alt+Del to restart.
Then following this link, and it is fixed! The OpenSUSE is completely gone.
I chose method 1 - Startup Repair. This time the PC recognizes Windows is installed on the C drive.
