Windows 7: Is it possible to change default OS at boot?

If there is no option to change the display time to see my list of OS at boot up then I guess this is the only way.
Sadly I will have to install all the software that I use again.

He has a bootable Win7 disk which can access files using Copy & Paste - in Windows Recovery Console. I was just suggesting a method to confirm no data is on C or determine for sure where each OS is before reinstall.

But if he's sure he installed to first partition then unless there's something he really needs off of there he can wait til he reinstalls to Explore for his XP partition and access his data on the other partitions.

You have to reinstall your software anyway on a Clean Install of Win7. This time look over these steps for Clean Reinstall - Factory OEM Windows 7 which compile everything that works best.

If you're sure you have your data off C then format it first. The booted installer will do this anyway if you don't.

I attached an image with the list of partitions and advanced options below. Do I select partition1 and click format?
You don't format anything.

You tell Windows where you want to install.

It then does the necessary, to include formatting.

Hi All,
I did a reinstall of win7. My problem seems to be resolved.but I'm so confused.
I get 3 options while boot up.
Old version of windows (most likely XP sp2), 1 windows 7 and one windows xp installation set up ( which must be the XP sp3 corrupt installation file). This is how it was before I ruined things..
So I think the install of win7 overwrote the last win7...

All my program files still exist. I
Got to windows old and recreate all the shortcuts which existed on my desktop before this issue..I think i will survive with this.. rather than try to remove the corrupt XP sp3 which is still the default OS trying to boot at install.. I will
post pictures...

First thing you should do if post a picture of Windows Disk Management so we can see once and for all what's going on.

If the new install in fact boots, you should get anti-virus installed before you go very far on the net.

Have you confirmed you have an Internet connection on the new install?

If the Windows Disk Management pic checks out, you should be able to delete unnecessary partitions from that screen.

Yes the Internet works fine... Which is like last time when I didn't have to do anything to get it working..
Now windows 7 boots fine... It did ask me stuff to do when a fresh install is in place.. Like giving a name to the PC ...
Only thing is that Everytime at start of the machine I need to change the OS option to windows 7 else it goes into that endless loop of installing sp3 attempt.
Another change I see is that disk space on C drive is eaten. Earlier I had 16 GB and after win 7 install it became 9 GB now it says 3.5 GB.

Show us the pic of Windows Disk Management.

Preferably a screen shot, rather than a camera snap. But something.
