text: If you have Windows XP or Windows 2000, follow these steps:\n\n1. Take a backup. In case things get mucked up, you have something to go back to.\n\n2. Boot up your machine to Windows.\n\n3. Right-click on My Computer and click on Manage.\n\n4. In the left hand tab, click on disk management. The corresponding right hand tab would should you the disks you have installed along with partitions. The linux partition should be shown as "Unknown" or "Not Recognised". \n\n5. Right click on the Unknown partition and select "Format". This is the final frontier, and if you format the disk, there is no way going back to linux, (not easily anyway). \n\n6. Once format is done, assign a drive letter to it and the new drive with all its empty spaces should show up in your windows explorer.\n\n7. We are not done yet, assuming are using a boot loader (GRUB or LILO), you still have to remove that or you will be stuck at a LI or a grub> prompt. You may need the Windows XP/2000 CD, so keep that handy. \n\n8. Reboot, if you can see the boot loader, select Windows, and you should be fine.\n\n9. In case you cannot, boot with the CD and select the recovery mode. \n\n10. Once you get to the recovery console prompt, type "fdisk /mbr" and reboot once you get back the prompt.\n\n11. Enjoy Windows!!\n\nIf there is anything you do not understand above, DO NOT ATTEMPT THIS AS IT MAY SCREW UP YOUR SYSTEM AND YOU MAY NEED PROFESSIONAL (READ COSTLY) HELP IN YOUR AREA. Better leave it to a local guru or have one handy atleast.\n\nEnjoy!!\n\nYou should backup anything you think is valuable to you. It could be source code, photos, important lettes, documents, excel sheets, etc. etc. Basically whatever you cannot live without.
