I installed Ubuntu 13.04 on a Lenovo ThinkPad with Windows 8 preinstalled with great difficulty. To make it run, I edited the boot command by adding the following line:

acpi_osi=Linux acpi_backlight=vendor.

I was able to boot once into Ubuntu after running boot-repair. But then subsequent times onwards, I get stuck with a blank screen in spite of giving the above options. I ran boot repair a couple of times more using a live disk and a live USB. It still gets stuck.

I've noticed a few things. I've got a lot of partitions on my disk now. There is a partition for Windows 8, a partition for Lenovo backup files, 2 partitions (around 200GB each) for miscellaneous purposes and one more partition for Ubuntu. Everything else, I'm not sure how they've appeared. Can anyone guide me?

1.First run this command on ubuntu,to know proper chaining was done or not,

sudo os-prober

IF it shows like this /dev/sda1:Windows 8 (loader):Windows:chain,then proceed to step 2.

2.Run the windows installation disk,select repair option and open the command prompt.Run the below commands on the displayed command prompt

bootrec /fixmbr
bootrec /fixboot

  • boot into windows.Then download EasyBCD software.Under linux tab set Grub2 as bootloader and add an entry for ubuntu by locating the partition where ubuntu installed.And also create boot entry for windows partition. – Avinash Raj Nov 02 '13 at 07:21
  • I downloaded EasyBCD, but I couldnt find any Linux tab as you have mentioned. Is there any tutorial you can point to? – Torpedo Nov 02 '13 at 10:33

  • I tried that. But it didnt work. Actually, I am getting the grub for Ubuntu. It contains Ubuntu as well as Windows OS for selection, but when I select Ubuntu, it fails to load with the problems I've mentioned. – Torpedo Nov 05 '13 at 18:58
