If, after giving Linux the good college try, you decide that it is just not for you, you decide to delete Linux from your system. Unfortunately Linux loads it's own Boot Loader (Grub Bootloader) which, when you delete the Linux partitions, is also deleted. What do you do to get your Windows MBR back. Here is what you do to delete Linux and get back into Windows. (This works for my Win 7, I suspect it is similar in Vista, possibly in XP as well. My hope is that others will add to this thread with the steps for those OSes as well.)
1. There are 2 ways to get to Disk Management: Type Disk Management in the search box and select Create and format hard disk partitions. This will open the disk manager.
Or Go to the Control Panel and double click on Administrative Tools, Select Computer Management (Or just type cmpmgmt.msc in search). Select Disk Management.
2. Delete the Linux partition and the Linux swap file partition.
Unfortunately I did not grab a pic before I deleted the Linux partitions, sorry
3. Insert your System Repair Disk and reboot. Choose to reboot from the DVD
4. Choose to repair your PC. Choose the Command Prompt option and type "bootrec.exe/fixmbr" without the quotes. Press enter.
That's it. You can now reboot into your windows partition. Linux and the Grub Bootloader are gone. The last chore is to go back into the disk manager to recover the unused space deleting the linux partition has left.
