Windows – Can’t install Windows 7 on extended partition

installationpartitioningwindows 7

I am trying to install Windows 7 in a dual boot configuration on a PC that's already running Ubuntu 8.04.

Windows 7 is kind enough to refuse installing very early in the process, issuing the following error message:

Setup was unable to create a new
system partition or locate an existing
system partition

Update: I found this thread describing a struggle with a similar issue. The "solution" there was to disconnect all drives except for the one on which Windows 7 is to be installed. This does not work for me!

Any idea how to solve this problem without wiping clean my Ubuntu installation?

Use gparted live CD and move the Ubuntu partition towards the end of the disk. Windows 7 wants to be in the first partition (don't know if just creating a 100Mb "boot" partition is enough).

You might want to take a look at this guide before you get that done. There is a section for reloading grub mentioning that for 10.04+ with Grub2 the guide is on a different page. Also there is a similar question here in superuser.
