64 bit Windows 7 is in the machine. I Download 64bit iso file and make a CD. I set the BIOS, let the CD Drive as the first Boot option. When I tried to Install Ubuntu, it starts the process as normal.
Windows 7 is in Drive 'C'. As a came to know, It should recognize the existing O/s withing the process and should appear it on the Monitor. but the machine says there is no O/s, so Choose 'C' or some where else. In addition it says, I will loose just my Data files.
So I stooped the Process to avoid loosing my existing o/s. I tried it several times and got the same experience.
Then I boot Windows 7 and run 'Wubi' file. The first window is appearing normal. I can select the Drive where to Install Ubuntu & selected the Quota for Ubuntu, user name, password. When I continue, it goes to next window and doing some process for few seconds. Then the Process is stop (critical Stop), and the massage says, it cannot find disk images.
It happens again and again.
Can somebody guide me pls ?
