I have a new laptop which comes with Windows 7. I want to dual-boot it with Ubuntu 9.10.

I have burned the install disk of 9.10, but during the install process, I am stuck in 'setup my partition'.

It has 2 options:

  • wipe out my whole hard disk
  • manually configure

I don't want it to wipe out my whole hard disk (I want to keep my Windows 7).

But how can I manually configure the partition to use the free space and create a partition so that I can install Ubuntu 9.10 and swap space?

When a Windows installation already occupies the entire hard drive, its partition needs to be shrunk, creating free space for the Ubuntu partition. See How to Resize Windows Partitions to learn how to do this.

This can be done through Control Panel -> Administrative tools -> Computer Management -> Disk Management. You can then use the partition manager to shrink the partitions. As a side note, you can only create free space to the right of a partition.

If you have resized the windows 7 /vista partitions and cannot boot up windows, you can use the instructions from WindowsRecovery to fix it. Once free space has been created on the hard drive, it is easy to install Ubuntu as the second operating system (and it is done automatically) from the Ubuntu LiveCD. Allow the Ubuntu LiveCD to install to "largest available free space" (if you have left unallocated free space), or manually into a partition that you have already created for Ubuntu.

you want to install Ubuntu on a single partion Dual Booting, Select Guided – resize. In the New partition size area, drag the area between the two partitions to create your desired partition sizes. Click 'Forward. The Who are you? window appears.

I have used the Windows7 disk management tool. And I have shrunk and created 2 volumes: 1 10GB for swap, 1 29.GB for my ubuntu. But when I boot up again with ubuntu live 9.10 CD, it does not install. I keep getting this 'Setup Parition' and I don't know how to move from it. Please help. – michael Apr 13 '10 at 4:28
you should take a look at this guide ( – Ye Lin Aung Apr 13 '10 at 4:37
Thanks. But for me (I am using 9.10 live cd) on a laptop with window 7. I only see 2 options 'Prepare disk space': Erase and use the entire disk' or 'Specifiy partitions manually (advance). There is no 'Guided resize' or 'Guided entire disk' options. – michael Apr 13 '10 at 5:48
"Guided resize" is an option after after "Specify partitions" I think. And there are another couple of stages before anything gets actioned. I have shared your nervousness and desire to get it right. As long as your Windows 7 partition is backed up and you have a reinstall disk or similar, then you won't make any irretrievable moves. – outsideblasts Apr 13 '10 at 5:56
no. I don't see 'Guided resize' after Specify partitions. At least I don't see that in 9.10 live CD. – michael Apr 13 '10 at 6:17
