|I did a lot of searching and most of the proposed solutions require a Windows installation CD.|
My computer did not come with Windows XP installation CD, it just came with a Toshiba Recovery CD, which is not the same thing. And I could not create a Boot Disk because my laptop doesn't have a floppy drive.
I finally figured out how to remove Ubuntu from my computer and get it to boot in Windows XP. I had to do a complete reinstall of Windows. This will cause you to lose all your data, so backup before proceeding.
You need a free program called MbrFix. To use it, You must log in as administrator in Windows Safe Mode.
Start your computer.
Arrow down to Windows
Hit Enter and tap the F8 key immediately.
Log in as administrator.
Open your browser and go to:
Download it. If you can't find it Google MbrFix
Then extract the contents to C:\
Go to Start, click on Run and type 'command'
This will open a terminal.
You will get a C:\> prompt
Enter: MbrFix /drive 0 fixmbr /yes
Now the GRUB menu will be gone and you will automatically boot into Windows.
Delete Ubuntu partition(s) by going to to the Control Panel>Computer Management>Disk Management
Run the Recovery CD to reinstall Windows
