Dual Installation of Ubuntu 14.04 LTS along side Windows 7

This is share some experiences in installing Ubuntu 14.04 LTS along side Windows 7 using wubi.exe. It turns out the process is not as straight forward. First I will describe a few processes which were tried but won't work. The scenarios describe involves installing Ubuntu 14.04 LTS 64 bit on Windows 7 64bit

Firstly download the Ubuntu ISO from

After download the ISO, on the Windows 7, mount the ISO image in the MagicISO (which can be downloaded and install from In the mounted disk, copy the wubi.exe out into an empty folder. Now unmount the ISO and copy the ISO image file into the same folder as the wubi.exe.

Now double click the wubi.exe and follow the instruction to install. After the installation is completed, restart the computer and selects the Ubuntu in the operating system manager. When entered in the Ubuntu, with the "*Ubuntu" option selected, press the key k to go into GRUB boot entry, now locate the following line:

RO- linux /boot/vmlinuz-3.13.0-24-generic root=UUID=AAC884AC1F144321 loop=/ubuntu/disks/root.disk ro quiet splash $vt_handoff

Change the RO and ro to RW and rw, as shown below:

RW- linux /boot/vmlinuz-3.13.0-24-generic root=UUID=AAC884AC1F144321 loop=/ubuntu/disks/root.disk rw quiet splash $vt_handoff

Now save and continue, the above step is to prevent the error: "Serious errors were found while checking the disk drive for /". Once goes into the Ubuntu, we want to make the change to the GRUB entry permanent so that the error won't appear next time. To do so, open the terminal and type the following commands:

$sudo gedit /etc/grub.d/10_linux

In the file, change ro to rw. Now save and closes the file. and type the following command line:

$sudo upgrade-grub

Below describes a few "traditional" ways which won't work for the dual installation of LTS 14.04 on Windows 7:

1. Mount the ISO in MagicISO and double-click wubi.exe to install: this is the way for the Ubuntu 12.02 and earlier, but if you do it for LTS 14.04, you will probably get the following error: "None Type" object has no attribute 'get_info'
2. Burn the ISO image into a DVD and tries to boot from DVD to install: this is another way which works for the previous ubuntu version but not for LTS 14.04, it will throws the error: "None Type" object has no attribute 'get_info'
