Bootmgr is missing - Server 2008r2

When you come across the error "Bootmgr is missing" in windows 7/Server 2008.
the answer is:
Load a windows cd(7/2008) for the apropriate OS and boot it, then choose "reapair my computer" , then choose command promt.(in case of HW raid, load the proper drivers first)
Type: cd recovery
Then type: startrep.exe
If you're lucky this will solve your problems automaticaly.

In my case it didn't so i had to do it manually, first of all when in the commandpromt enter:
bootrec /fixmbr
if this doesn't resolve it, make sure the right partition/disk is set as "Active".
it has to be the small partition that goes before your main drive(C:)

go back to the command prompt and enter diskpart
now enter list volume
look for the said volume (it's about 100mb)
select volume
type: Active

then make sure none of the others are marked active, select them by using
"select volume ".
Then type: Inactive

now you shoud be able to boot without problems.
