1. Until you get a more permanent/elegant fix...
Make [and boot, and use to load Windows] either:
(a) This Windows NT 4.0, 2000, XP or Server 2003 boot floppy disk (http://www.nu2.nu/bootdisk/ntboot/).
And/or...
(b) Use this ISO file to make the bootable CD version of the floppy above (http://www.paulski.com/bootcds/bootxp.iso).

(c) When you boot one of those disks you will be presented with a menu of 8 choices made up of 2 physical HDD's, each with 4 partitions.
Choose the one you think holds your "Windows" partition [normally the 1st at the top of the list].

2. What I think is causing the problem:
(a) When you installed Ubuntu, you probably installed GRUB.
The 1st part of GRUB was probably installed to the MBR. [Can you confirm?]
So the MBR is now not suitable for only booting Windows alone.
(b) The 2nd part of GRUB was in [a file in] the Ubuntu file system.
When you eliminated Ubuntu , you lost the needed file that allowed you to choose to boot either Windows or Ubuntu.
GRUB will therefore no longer function.
You are no longer offered boot choices.

3. [B]The proper/elegant needed fix:
Is to to restore the normal MBR [as it was before GRUB was written to it].
With your present state of knowledge, do you have a favoured method you would choose to use to do that?
Any backup of the MBR as it was before the change?
Do you have the Windows installation disk handy?

The standard fix is to boot to the Recovery Console (http://support.microsoft.com/kb/314058) and enter fixmbr there.

If you don't have a Windows installation CD there are other workarounds.

Hi
While booting the computer press F8 before you get the Windows Logo on the screen, you will be given a option to boot the computer in safe mode.
If you are able to boot the computer in safe mode then do a clean boot (i.e) run msconfig from the run command and disable all the non Microsoft services and disable all the start up items and restart the computer.
If you are unable to boot the computer in safe mode check with Last Known Good Configuration option. Even if that didn't work then i think you have to use your recovery CD , but mind you you may loose some data stored in My Documents folder

While booting the computer press F8 before you get the Windows Logo on the screen, you will be given a option to boot the computer in safe mode.Until GRUB is removed there is no hope of booting directly from the BIOS to Windows. A workaround would be to use a third party boot manager such as SBM (http://paulski.com/zpages.php?id=1612) which will set the active partition appropriately and bypass the normal MBR.
