Hello,

Ok so I'm running Ubuntu 11.04 on my Acer extensa 5620. I need to install windows and setup a dual boot on this machine. Here's what I did. I followed the instructions on this page

(http://gparted.sourceforge.net/larry/resize/resizing.htm)

and resized my home partition (which is differenet from the file system partition). Anyways, I resized the partition and made a new NTFS partition. This was all done from Live CD. I then rebooted and then tried the windows installation CD. Now here my problem crops up.
Windows says that no partition is found. What have I done wrong? Any ideas? Can the drive be damaged or have I made a mistake some where? I did not specify a mount point for the new NTFS partition, does that matter?
Any tips or help would be greatly appreciated people, thanks!

windows often disagree if its not installed on a primary partition at the hdd beginning; so maybe you need to move your partitions a litle bit. And of course this ntfs partition need to be bootable.

what you need for ubuntu:

Thanks dino99. I'm still lost though. How do I move around the partitions? What do you mean by that? Also, how do I make it bootable? Will I have to do these things again with gparted from liveCD?

The NTFS partition has to be a primary sda1 thru sda4 and has to have the boot flag (active partition in windows). Windows will only install, boot or repair a partition with the boot flag.

Some BIOS will not even let you boot unless you have a boot flag on a primary partition. Grub does not use a boot flag.

If you're still mystified, Radhavictory, I suggest you post either the output of "sudo fdisk -lu" (between
and strings) or a screen shot of GParted showing your disk's partitions. That will give us the information we need to provide more specific recommendations.

Thanks srs5694, you are right, I am still mystified. Here is a screenshot of my partitions shown by gparted.
