I have already install win XP then I have install UBUNTU 7.04 in free space but next time WIN XP not in bootable option, and system directly enter into ubuntu
then vise vesa....
First I install Ubuntu7.04 in free space then I install WIN XP in partitiion C: but now system directly enter into XP without giving dual option. but ubuntu partition is still show in device manager. image is attached (problem in atached uploading require Karma >60 ???????)
My personal method for adding Ubuntu to dual boot on existing Windows machines goes as follows: 1) Delete all unwanted files. (not file system files, user files for your Windows system): Things like old zip files, movies/music/media files, anything you no longer need or want that are simply taking up space in your drive. 2) Uninstall all software yoy KNOW you will no longer use. Examples of things I will look for first when I do this are as follows: unused toolbars, redundant virus pritection packages, unessential windows components. 4) Using basic Windows utilities, which are mostly found in the control panel, I clean the file system, repair any existing file system problems, then defragment the hard drive.
It sounds like you either did something wrong when formatting your hard disk, or you did not install GRUB, the boot loader, correctly. Did you follow a howto?
Since you're talking about C: partitions, I'm guessing that you used a Windows partitioning application. I can only advise to first use Ubuntu's partitioning tool and allocating every needed partition for Ubuntu and Windows there. Afterwards, install Windows in the partition you prepared, and then install Ubuntu in the other partitions you prepared.
If you're sure that you have partitioned and installed correctly, reinstall GRUB.

Windows NT (XP, Vista, 7, Server versions) all use NTLDR (NT Loader) and Linux uses lilo, or grub (legacy is version 1), or gub2 (newest grub version 2). NTLDR cannot see Linux/ext file systems, but grub or grub2 can see FAT/NTFS file systems and Windows......
All that being said, yes, having Windows loaded first and then installing Linux second, is the best way to do it on a dual-boot system; however I question the use of such an old distribution as Ubuntu 7.04 which isn't even an LTS (Long Term Support) version and reached EOL (End Of Life) for support a long, long, long time ago. Ubuntu used grub (version 1) until Ubuntu 8.10 with Ubuntu 9.04 being the first versuon of Ubuntu to use grub2.
Now, finally to add onto this, I think use a non-LTS version of Ubuntu (which is really a mid-term release every 6 months which introduces new code because it's really a beta for the next LTS version,) is a bad idea. Ubuntu 6.06LTS reached EOL long ago, Ubuntu 8.04LTS reaches EOL on April 28th, 2011, a mere 10 days from this posting of mine, and the current LTS release, Ubuntu 10.04.2LTS is the one I'd recommend for two reasons:
1) It's an LTS release so it's far more stable than a non-LTS release is....and 2) It's the current LTS release and thus supported for 3 years total on the desktop until April 2013. (support meaning newer code, security updates, compatability, etc....)
If someone were to ask me for support for say Windows 3.1.1 or Windows95/98/2000 or any old OS, even with XP, I'd still recommend using the latest OS possible for the sake of support, newer code/compatability, security, etc.
