How to fix Windows 7 Boot Manager when failed to start?

After I repartitioned and installed Slackware64 on my laptop, the Windows 7 failed to start. The error status is 0xC0000225 and the error message is "the boot selection failed because a required device is inaccessible". This problem is easy to be fixed as long as you have a Windows 7 Recovery Disk. You just boot your PC/laptop using this disk and follow the instruction for repairing the Windows. After repair is finished, the disk will restart your PC/Laptop, then, you will get back the Windows 7.

Please note that you have to use the same version of recovery disk, I mean, if you have Windows 7 32-bit on your PC/Laptop, you have to use Windows 7 32-bit Recovery Disk, vice versa. You can create your own Recovery Disk from your existing Windows 7. For further information about creating Recovery Disk, please consult to Microsoft website.

How to fix my silent laptop?

I have some problems with my new laptop: HP Pavilion dv3-4036TX. The first problem is the laptop was silent --it was no sound on the speaker-- after I installed Slackware64. However, if I plugged my headset to the  headset plug-in port, I can hear the sound clearly. The simple steps for fixing this problem:

• turn off the alsa using /etc/rc.d/rc.alsa stop
• run alsaconf then follow the instructions

Please note that you have to run the steps above as root.
Now, I can hear my favorite songs from the speaker.

The first problem is solved. There are another problems that still need to be solved. I will share to you after I find out the solutions.
