Hi,
I am new to Linux and obvious LinuxForums. I had some problem with the installation of Linux. Please find the details and advice me for a solution.
1. My laptop is Compaq Presario CQ56 - preloaded with Windows 7 OS.
2. I downloaded the latest version of Ubuntu 12.04 to my windows PC and created a bootable USB.
3. Tried the Ubuntu in my Windows and Installed it from the windows. Created another partition for linux and after some time got one message like the installation is successful.
4. When I rebooted the system, Its not shown the linux option in the bootloader. So I read some threads in the LinuxForum and did some grub update like this
sudo fdisk -lsudo mount /dev/sda6 /mnt sudo grub-install --root-directory=/mnt /dev/sda6 sudo update-grub
5. After that my Pc is booting to Linux only. Its not showing the Windows 7.
Can anyone please help me to resolve this issue.
6. For easy understanding the problem, I am pasting some additional information about my system.
