Booting sequence. Ubuntu 12.04 installation and cohabitation with former OSes
- by Stephane Rolland
I am on the brink of installing Ubuntu 12.04 Precise Pengolin on the first primary partition of my hard-drive. (A day in History for me since I had always kept a MS windows at this first place).
But I have some fears:
This is my last computer available (In the past I used to have 2 or even 3 machines so I could always un/plug HDs for recovery operations and rescue)
The current booting sequence is not straight forard.
So as to explain the boot sequence let me briefly sum-up the history of this laptop computer.
It was a dedicated Windows Vista computer. 1st and only Primary partition.
Then I added Windows 7 (on the 2nd primary partition) letting the Windows Vista Boot Loader manage the boot sequence.
Then I added Ubuntu 10.04 Lucid Lynx on the 1st sub-partition of the Extended Partitionm asking Grub to be the boot loader. But when I ask Grub to launch windows it launches the Vista BootLoader that manages the choice betzeen Vista and 7.
So in theory Grub is on the MasterBootRecord - though I understand where the Vista BootLoader remains.
Now, I will no longer use the Ubuntu 10.04 ( on extended partition) and also the Windows vista (on the first primary partition).
I will install Ubuntu 12.04 on the First Primary, asking it to install a new bootloader.
I want to keep the Windows 7 that is already on the Second Primary partition. And I want it to be loaded by the Ubuntu Boot loader(I don4t knoz zhich is included in this version)...
And I am afraid the last point will not work.
