boot mgr missing(8 posts)
My suspicion would be that you have no active partition. Check that first. It is either C or the 100MB system partition that has to be active.
Use the bootable CD of Partition Wizard for the inspection (last entry on the webpage). Should there be no active partition, highlight C and make that active. The controls are under the Partition tab > Modify.
The 'active' status you can see (or not) under the heading 'Status'.
