I am facing a problem. After installing Ubuntu 12.04 LTS using Live CD, at the reboot there is no boot option to choose the OS. I directly get logged into my Windows 7.

Before that i was having an issue with the 'nomodeset' if not mistaken .After ticking [x] on the nomodeset, i can install my Ubuntu, but got stucked again at choosing the partition option.

So i did 2 partitions for Ubuntu, 1 partition as ext3 for / and the other 1 for swap. Which enabled to proceed until the finished installation dialogue, and after that system wants to reboot .It takes some time and gets stuck at the screen doing nothing, doesn't reboot at all.

I did forced shutdown then rebooted again which directly logs me in windows 7 without boot option. In win7 the partitions for Ubuntu is gone.

I tried the boot-repair thing and it doesn't help .It just shows up the _ Blank Cursor (terminal thing i guess). I typed boot repair but still the same result.

I am using Acer Aspire 4736z.

Please somebody help me with this issue.

  • did you followed the steps mentioned here ? https://help.ubuntu.com/community/Boot-Repair .. if so and its not working, post the url of boot summery (see here for instruction http://ubuntuforums.org/showthread.php?t=1821980) – Web-E Jun 23 '12 at 09:25
  • yes. i type the sudo thing. and it said no kernel found. sumting like tat. – utamaku Jun 23 '12 at 09:35
  • How can any one help you if are not mentioning clearly what is the problem.. that above step should be done from a live cd. and post the exact error – Web-E Jun 23 '12 at 09:59
  • im apologize for the lack of information. later i will note down all the error i get.sorry again. – utamaku Jun 23 '12 at 10:11
  • I apologize but I am having a hard time understanding what you are trying to do. Do you want to creat a dual boot installation where after starting your PC you get a list A=Ubuntu and B=Windows7 or are you trying to do something else? – Yosi Jun 23 '12 at 09:00
  • yup. i try to make dual boot. and 1 partition for each os. – utamaku Jun 23 '12 at 09:34
  • for my win7 i had the part already. the new one i did was for ubuntu and its swap. – utamaku Jun 23 '12 at 09:43
  • If you had (or have still) the same problem, you will understand what he wants. I think he has a GPT. I was not able to fix it yet. – LittleByBlue Jan 28 '15 at 16:53
  • This link may be helpful for you. http://askubuntu.com/questions/813241/ubuntu-16-04-installation-with-windows-10/814153#814153 But make sure that the partiton is formatted in which you have to install Ubuntu. This solved My issue,hope so Urs too will be fixed. – Chetan Aug 23 '16 at 04:09

while you come to partition screen go to last choice something else and next screen you have to make two partitions / and swap.while making / partition select ext4 file system ,format partition and install.down u have boot loader partition selection .Put it to first partition sda1.when re booting you get grub menu .
