Is it possible to change default OS at boot?

Yet another image.
Please let me know if you need a better snap. As I can't figure them out clearly on my mobile.
The detail partition info for other partitions is same - shows as healthy.

You did not get the Details for Partition 1 because it was misspelled. Please try again.

It should be marked Active since it is the only Primary Partition so it must be Active in order to boot the OS's. I'm assuming it is XP. Do you know this for sure?

Do you remember where you installed Win7?

Hi Gregrocker.
I don't need XP anymore. I want to use windows 7. When I installed win 7 it kept a windows.old file and I didn't lose any program files... So I just created shortcuts to programs and kept them on desktop.

Just a suggestion, go to adminastrative tools--- computer management---- Disk management. Look for the partician with xp on it and format that partician. Unless you have other files there that you dont want to loose as formating will erase everything. At least look at you hard drive particians while you are there and then maybe post some new info here before you do anything...

Oops. Attaching for partition 1

Greg, I like the picture, Maybe you can start a new topic Called Floatware not Bloatware..... Ha Ha..

If you don't want XP did you install Win7 over it? From the way you describe it you must have run the Win7 installer from XP which is incorrect. The installer needs to be booted to correctly install to its partition.

Do you remember which partition you installed Win7 upon? You have 1 39 gb Primary and 3 39gb Logical partitions which are each too small to install Win7 comfortably. What I would do is boot the installer and use the Drive Options pictured in Steps 7 and 8 of Clean Install Windows 7 to delete all partitions, create and format one large partition to install Win7 upon.

Did you back up the files you need before doing this? You cannot use the old Program Files so unless you need to rescue files out of Windows.old I would just start over with a clean slate.

Greg,
Win 7 was installed in C drive. I know for sure.
What I don't know is where the bad xp sp3 is. Is it loading from C drive or some other drive.
If its definitely from C drive then I don't mind formatting the entire C drive as long as I don't lose data on other drives.

Your data should always be backed up in case of drive failure. Are you saying you still have data you cannot afford to lose on some partitions? Which partitions exactly of the four you have need to have data preserved?

Are you sure you installed Win7 on the first partition? There are no drive letters now so you need to know this. It is the only Primary one which can boot Win7 as of now but its not booting so perhaps you installed to another?

If you want to try to start up Win7 then boot into the disk to run Startup Repair a few times, report back the results.

There's a chance you overwrote Win7 on C with the bad XP install. If so then what I'd do is reinstall Win7 to C, move your data out of the second partition, delete it in Disk Mgmt and then Extend C into the space to make a reasonable size Win7 partition. You may need to use Partition Wizard to Resize C into the space if the Free Space created by a Deleted Logical partition will not also delete in Disk Mgmt. We can help you do this after you decide what you want to do.

Greg,
I initially had 16 GB space in C,
All I did was to load the DVD, and let the system boot. I then installed windows 7. Prior to start of installation I chose C drive.
It then went about its way of installing the OS.
Trouble started when I unchecked the time to display the list of OS.

So if I can't list the OS installed in the machine through BIOS and if I can't do anything to boot options( change the time to display OS at boot to 30 seconds) from command prompt to show the list of OS to boot then the only option is to clean C drive completely right.
