I am trying to clone/backup a disk with Windows 7 Pro 64bit on it. First I tried Easus Todo Backup and used disk clone option without sector by sector copy. I then plugged in the new drive and I get the following error.

"Invalid or damaged Bootable partition"

I then plugged the old drive back in and I am greeted with the same error.

My next step was to try the sector by sector disk clone, but still I get the same error. I have tried fixing the mbr with the windows disk but that makes no difference.

I have tried some other free tools and I get the same error.

I have tried this on a different machine running Windows 7 Enterprise 32bit without this problem.

I have done some searching and the only thing I can come up with is this post from the Acronis forums

suggesting that the bios is reading my disk geometry incorrectly.

Can anyone shed any light on this, is there a way I can fix this either in the bios or repair the mbr every time I reimage it?
