Finally put this system to install, the land continued to get 4, 5 days (Crash ...), has always been to use a U disk to install Ubuntu, quite simple, but this host can not recognize the USB flash drive do not know why ... The problem is Baidu and Google eventually found no reason to give up. Had to re-search the online drive system, fortunately there is a corresponding article on the Internet, the process of the XP Ubuntu dual system is very detailed, but there is a pit ... Just follow this process.
Just click on install Ubuntu and give me a mistake.Grub Error 15:filenot foundOnline said this error may be because the root (hd0,0) partition This is wrong, changed for a long while not to say this reason, inadvertently saw an article on the 64-bit ISO image and 32-bit ISO image Casper folder under the different kernel files, 64 bits is Vmlinuz.efi, 32 bit is vmlinuz, this I pit of ah ...
Fortunately, the next step can be done, do not know is the reason for this way or the host is too old, in the time of the partition is very very slow, the host of the graphics card there is a problem from time to time on the black screen, to adapt to the resolution, Division is a slightly longer time to install the system. When prompted to restart, but very happy.
But the restart was complete, Md. Boot time without the boot of Ubuntu, or only XP and a installubuntu option, in the installation of the system I pay attention to/boot this partition, give the space is not less than 512, I remember to do a This operation, there is an article said, Go to the installation page via Installubuntu and then CD to the/boot directory, then write two lines

After the implementation of the XP startup items are all gone, this to crash ah .... Give me the hole. I had to re-fix it with Chinese cabbage
The boot entry for XP. And then started the search for Ubuntu installed without the startup item, "Grub hard drive is finished installing
Ubuntu does not display the startup item "Through this search, finally it was put to me to save,

The article mentions a boot repair Linux software, the function of this software is similar to the public power of the Chinese cabbage,

Open Terminal input sudo add-apt-repository ppa:yannubuntu/boot-repair&& sudo apt-get update
Open the terminal again and enter:
sudo apt-get install-y boot-repair && Boot-repair
(In the middle there will be a hint, follow the prompts to operate on the line) after the restart, the magical system installation is complete!
