Solution to problems encountered during Ubuntu Installation

The installer is installed in the wubi.exe file in window764.
Http://www.ubuntu.com/download/desktop

You can download to the ubuntu-12.04.1-desktop-amd64.iso image file, you can choose a different version based on your personal interests, but also according to your current system type, 32-bit or 64-bit.

The correct method for installation is To uncompress the wubi.exefile and store it in the same directory as the. isofile, and then run wubi.exe. Okay, don't download it.

The general steps include: wubi.exe -- let's select the partition to be installed, and set the password -- the installation process (this process is sometimes fast and sometimes slow) -- Let's choose whether to restart immediately or restart later -- there is another installation process after the computer restarts (this step takes about 5 minutes, depending on the computer configuration) -- Automatic Restart (select UBUNTU) -- a prompt will be displayed. Enter the password you set to log on to the system.

Some problems occurred during installation
1. If you do not need to extract the isofile and click wubi.exe to install it, The wubi-amd64.tar. xz file will be downloaded again.
2. Sometimes anti-virus software will prevent installation,
3. I have installed the wubi.exe file several times and I will remind you to use the Administrator's permission to run the wubi.exe file (right-click the file and run it as an administrator)
4. "cocould not retrieve the required disk image files" and reformat the partition of the system you want to install.

My computer is HP dv4-5a02TX, installed many times, in fact, has been successful for a long time. The problem occurs when the installation process is restarted, and a black screen is displayed. I started to feel inexplicable. I was discovered by my colleagues later.

completely black screen, you can also see the shadow of the dialog box, but you cannot see it clearly. So I thought this installation was not feasible. I had to install it again, but there was still a black screen. Because the computer configuration was relatively high, I thought I could not even install it, so I ran a few times, to press F3, people who have used this type of computer know that F3 is used to adjust the screen brightness ...... In general, the screen brightness is adjusted to the lowest when Ubuntu is installed. You need to adjust the brightness by pressing F3.
