In the instructions for removing Windows "System Reserved" Partition at http://www.terabyteunlimited.com/kb/article.php?id=409
it is mentioned to Part 1, paragraph 9:
"Copy the bootmgr file from the System Reserved (booting) partition to the Windows partition (make sure to use the drive letters as assigned on your computer). Run the following command:
robocopy e:\ c:\ bootmgr "
where "e" is the drive letter of the "System Reserved" partition and "c" is the drive letter of the Windows partition in this example.
I noticed that my Windows partition already has a "bootmgr" file in the appropriate place. Should I erase this file and then do the copy, or not do the copy at all ? The "bootmgr" file in my Windows partition is the same number of bytes as the one in my "System Reserved" partition.
