Looks like you are annoyed at Linux booting before you can change the boot option to Windows.
Instead of removing GRUB (& indirectly making it difficult for you to boot into the LInux Partiton) why not just chnge the default OS which be loaded.....
I have done it on my PC and it works like a charm.
All you have to do is:
Try this, go to your /boot/grub directory on your boot drive ie (hda or hdb) and edit a file called menu.lst, it's only in Ascii so you cant do any harm (make a copy b4 u start). You will need to login as root so you can save your changes! Now look for these 2 entries on the first few lines
Pretty simple stuff really timeout is the number of seconds the system waits
"default 1" is the title number in the menu of the program you wish to launch ie,
title Fedora 7
title Fedora failsafe
title Your menu option
Please note the first title entry is 0 & then 1,2,3 etc
So if you wanted "Your menu option" to load first after 20 seconds you would change the entries to:
