installing dual boot on Windows 7 system

Hi all,

I recently bought a portable with a Windows 7 system.
I want to install openSUSE 11.3 but I also want to keep Windows 7 - so I need to install a dual boot system.
On my desktop I have GRUB with Windows XP and openSUSE 11.3 and all works fine.

How do I proceed ? I did not find much documentation yet, but maybe I looked in the wrong places.

Any help will be greatly appreciated,


The installer will generally do it all for you. BUT ideally we like to see your disk partitioning. But not from windows (it’s useless)
Boot a live CD or get this and burn it to a cd:

Get us the result of:

fdisk -l

In a SUSE live cd you will need to do su -
But Parted opens to root

Thanks for your answer.
I tried to do it from the install DVD, but I got the message that my Windows 7 partition AND my “Recovery partition” would be erased, which I clearly do not want to be happening.

I’ll follow your tip and I’ll come back to you.


Have a look at this

Very important for you to provide the output from fdisk, because you have a Recovery Partition on your drive that you need to keep for your portable (lap?).
I’m not sure you have a free partition to install OpenSuse. I think you may need to use Parted, Gparted LiveCD or similar product to resize your HDD and create a partition with enough room to install OpenSuse 11.3.

Use W7’s utility (IIRC >control centre) to shrink the W7 partition by 50% (W7 seems to limit that), that’s usually more than enough to install 11.3.

We do really need to see fdisk -l

Not much point shrinking windows if there are already 4 primary partitions, a possibility that does exist.

The point was to make the OP aware that there is an alternative way to create space. If there is a 4th primary partition in use, clearly one will have to go if it isn’t the extended partition.
