Windows 7: Install windows 7,over Ubuntu

Windows 7 Ultimate 32bit

Hello guys,
I’m a new member .I read this question and its answers, and I found them related to my problem.
My laptop was containing Ubuntu system. I did these following steps to replace it with windows 7:
1- Entered a windows 7 cd.
2- Deleted all partitions and created new partitions.
3- Installed windows 7.
4- Finally, after downloading the system, it goes in a loop and restarts itself. Nothing happens.
After I’ve read these answers I applied them to my problem (I used the diskpart to clean my hdd, partition, format it), and the same problem existed.
The only thing that I doubt is that I used the installer to create the third partition, and not the diskpart.
Note: My laptop is DELL inspiron 14z,core i3.
I wish to help me what to do with my problem.

Where did you get Win7 DVD? Did you burn it yourself?

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. Next if an EFI BIOS, enable Legacy BIOS, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10 to open a Command Box, type:

SELECT DISK 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. We are creating the partition here to mark it Active which overcomes certain install failures.

Thanks alot gregrocker,
My problem was solved
i just followed what you told me

just I have another question

I have just one partition which contains the Windows 7 system, now if i want to create another partition i should use Disk Mgmt to mark it Active. Is that right? Do you mean by disk mgmt that i should go to computer right click then manage?
If I used the windows installer to partition the rest hdd and didn't mark it active, what will happen?

thanks with regards,

It says that the purpose of creating a partition using the Diskpart commands before install is so that it can be marked Active. You already marked it Active when you typed out the Commands. That is sometimes needed for the installer to see the partition intended for Win7. You should not mess with the Active flag afterwards. The System partition must remain Active for it to boot.

If you want to create a new partition on the same HD for data or any other reason, then shrink C in Disk Management to create it using these steps:
Partition or Volume - Shrink
Partition or Volume - Create New
