Install Android 

You can install Android to your poor old p.c 

Step 1: Downloading Android x86
The first thing that you need to do is download the Android x86 iso. I provided a direct link to the Kitkat build RC2 which is the latest build at the time of writing this. To see other builds,

go to the downloads page

Step 2: Bootable USB
Using the program Rufus, we are going to create a bootable USB drive. Select your USB drive from the drop-down menu and choose the Android x86 iso file and hit start.

Step 3: Booting from USB
Now on your PC, insert your USB drive. When your computer starts, go into the boot menu. This is usually done by pressing the  F12 or Delete button, but could differ depending on your system. Make sure to choose the option to boot from your USB.

Step 4: Installing
You should now be at the bootloader screen. Select the option to install Androidx86 to hard disk. The next screen will ask you about partitions. Personally, I have no use for Windows XP so I am going to completely format the drive and use the whole thing for Android. Of course, you don’t have to. You can just choose your primary hard drive from the list and make sure not to choose the format option on the next screen.

In my scenario of completely formatting the drive, here’s what I am going to do. Go down to create/Modify partitions. And choose sda.

In the Disk Utility I am going to delete the existing partition then create a new partition (make it the primary). Finally, I am going to change the type to Linux (number 83 on the list) and finally write the partitions out to disk.

Finally, I am going to choose the new partition that I just created. On the next screen, I am going to choose EXT3 as the format.

It’s going to ask if I want to format it, I am going to choose yes.

It’s going to prompt me if I want to install the grub bootloader. I am also going to choose yes.

Choose yes when it prompts for installing the directory as read-write.

Once it’s done, make sure to select reboot.
