I switched off/disable "Secure boot" and "Fast boot" choices from bios settings. And I installed ubuntu 14.04 on windows 8. I dont meet any error during installation. Unfortunately I don't get an option to choose between Windows 8 and Ubuntu 14.04. On start, I can only boot into Windows.
I had Ubuntu 12.04 alongside with Windows 7. Then I added some debian distribution on the extended partition. After some time I decided to clean up and reinstall linux (Ubuntu). In Windows disc manager I removed all linux partitions and merged the free space. As a consequence, I couldn't boot Windows. After using Win7 installation DVD I got rid of the problem (using some bootrec commands...).
I recently installed Ubuntu 10.4 onto an older computer. Upon trying to boot off the live CD, my monitor would go "out of range" (screen would turn black and display a hardware error message "out of range").
I installed ubuntu on the third hard drive of my pc, the first two being a 120GB SSD and a 1TB HDD for data on the windows 7 side.
Now I've just installed ubuntu 13.04 onto another 1TB HDD, went through the installation ok, changed the BIOS so that it would boot to this hard drive first automatically (although also doesn't work if i boot to it manually)
