Win7 the easiest way to add Grub boot Linux after activation

because the Win7 (Vista) activation method is to touch your OEM's slic information through grub, the primary boot partition MBR is occupied by this grub to activate WIn7. However, if you want to install Linux on a different partition at the same time, there is a problem: grub cannot be added to the MBR, or it will disrupt Win7 activation.
There are some complex methods on the web, but a lot of command lines are entered. Here are some of the simplest ways to find your own way without a command line.
and reloading Win7 or Linux can be easily repaired.
1, normal installation Win7 to C drive, and activation.
2, the normal installation of Linux to other partitions, and finally asked to write to grub, choose the Linux mount point/partition! This step is important because GRUB writes to Linux on a partition that does not overwrite the MBR grub! 3, then Win7 can start normally, but there is no option to choose to enter Linux. Download EASYBCD This software, now the newest is easybcd_2.0_beta_-_build_60, the newer the better.
4, open EASYBCD, in Add/remove entry inside, choose Linux,type Choose Grub, add your desired name in name, write a partition such as Archlinux,driver choose Linux. The partition chosen here is identical to the location where grub was installed when Linux was just installed. The partition number partition x may not be the same as the Linux installation, which is determined by the size of the hard disk. Finally add entry save well, view settings can see two options, one is the original Win7, one is just built.
5, restart, complete.
Finally, the boot sequence, the computer starts, reads the MBR grub (contains the win7 activation information grub), and then executes the Win7 bootmgr, displays the Win7 launches the boot menu, then can choose to join the ArchLinux boot item, Grub that goes into the Linux partition (this is another grub that is unrelated to the MBR), booting Linux through this grub, and this grub can be modified directly in Linux.
The core idea is that Linux grub is installed in a non-MBR partition and then connected to this Linux grub via Win7 's bootmgr.
After reloading the Win7, you can use EASYBCD again to complete the repair of Linux grub.
After reinstalling Linux, install grub to the Linux partition, Win7 no need to change.
