Windows install error - unrecognized partition style

[maxmiaggi]

Hello. I won't say I am new to ubuntu, I have around 2 months experience in working with it.

So last week, I had Windows 7 installed in my laptop, which wasn't working as expected. So I decided to remove it and reinstall it, but this time side by side with ubuntu.

So I downloaded Ubuntu 10.04 LTS and installed it in my laptop (I actually chose to remove everything and install ubuntu, my bad). So everything was proper till here, and then I made a partition. The screenshot explains it. Since Windows cannot be installed in ext4 file system, I made it as NTFS.

Now during installation of windows from its DVD, it pops up an error:
"Windows cannot be installed to Disk 0 Partition 3"
The details:
"Windows cannot be installed to this disk. The selected disk is of the GPT partition style"

Even though I format it then and there itself, the same error occurs. I even tried deleting the partition and recreating it, but with absolutely no success.

There is something called Partition Type - "Linux Basic Data Partition". I even tried changing it to "MBR Partition Scheme", "Microsoft Basic Data Partition", etc, but still no luck.

Now what am I supposed to do? How do I install windows in the partition? Please Help.

Thanks in advance.

Are you using 32 bit or 64 bit Windows?

[maxmiaggi]

32 bit windows 7

GPT is not supported by 32 bit Windows 7.

Well, I also have the DVD for 64 bit windows 7, but I prefer 32 bit since many of the softwares that I have are designed for 32 bit.

In that case, which partition style should I choose in order to install 32 bit windows?

[LinuxFan999]

You will need the MBR partition style (Master Boot Record).

I tried that, but with no luck. The same error occurs.

What motherboard do you have?

[maxmiaggi]

well, I have a Dell Studio 15 Core2duo, so dont have exact idea of the motherboard in it.
Btw, 32 bit windows used to work fine in it till last week

How much memory do you have? if you have 4 Gigabytes or more, you should use the 64 bit version of Windows 7. 32 bit Windows software works in 64 bit Windows.
