Excuse me for the long title that I've chosen. I made a logical partition for installing another OS which it was XP but, I forgot to change it to a primary one and after that my first OS which is a Seven would never load up. I installed Paragon Partition Manager on XP and it has a Boot Manager program which it can show a list of installed operating systems to select when the system is powered on after post screen. In that list there is just Seven and no XP. Right now I'm using the Paragon Boot Manager program to load my first OS. I know that I made mistake and now the first boot-able sector is became to the XP partition. What can I do now to correct this problem?
Sorry if it's not clear to understand.
