I recently tried to install Ubuntu Desktop on my laptop, but it wasn't successful, as I had the same problem on every startup.
The Ubuntu version I tried to install is 14.04, and it was downloaded from the official site. I had no clean disk, so I tried to install it from my USB. I went Ubuntu forums and found several ways to write my ubuntu.iso to USB. I had tried a lot of them, but every time I had the next problem: when Ubuntu is only loading, it writes something like No caching mode page found
, which is going before Assuming drive cache: write through
. After that the Ubuntu logo appears and five white dots under it. For 4 seconds all of them become red, and them nothing happens. The Ubuntu logo is just staying on the screen even after an hour of wating. For all this time the USB indicator is not flashing. I've tried to google this, but I had found nothing.
Then while searching forums, I found a way to install Ubuntu inside Windows (maybe it is important to mention that I have Windows 7 and Windows 8 installed on my laptop). So I mounted my ISO again and started wubi.exe where there was not any button to install it from inside. After several minutes I've got the issue: I typed H:\wubi.exe --force-wubi
in my cmd, and it worked. I pressed Install Ubuntu inside Windows, followed the instructions, and reached the end of the installation. After this I really got a possibility to choose Ubuntu as the OS, but even than I get the same problem: nothing happens. But this time I got the message, which says that installation of Ubuntu will continue on Ubuntu booting. I can press the Esc key and choose different ways of its loading, but any of the options leads to the same problem. Except Verbose Mode, where text is first displayed and then the same problem appears.
Ubuntu is installed on the clean logic disk.
How can I fix this and continue the installation?
P.S.: Setting "nomodeset" in F6 menu on booting solved my problem.
