Hello all, sorry for yet another post on this subject but I have tried all the other ones to no avail....so I installed Windows 7 way back during the beta and right from the get go have had this problem. I install fine and get into windows then take out the DVD and low and behold bootmgr is missing yada yada yada....put the DVD back in and it loads just fine. System specs are as follows... Asus A8N-E AMD A64 X2 3800+ 939 SAMSUNG 3Gigs DDR RAM PC 3200 WD 200 GB SATA Primary (windows is installed here) 160 GB Slave IDE for storage I have tried thus far running the repair option and getting no results from that, according to the repair options there is nothing wrong. I have tried removing the storage drive altogether thinking that it might be looking at the wrong drive and got the same Bootmgr is missing message. I looked inside diskmgmt and the primary drive IS set with the boot option....not sure where else to go with this. I installed with a clean format and I do not using dual OS's.
