My neighbor's Vista laptop was infected to the point that the Security Center could not be repaired, but everything else worked, so I partitioned his HD, installed Win7 on the new partition, hand-migrated as much of the data as I could, then ran the Migration Wizard (from Vista), saved the file on the Win7 partition, ran Migration Wizard from Win7 and transferred the settings, etc... to Win7.
Everything works. It's time to delete the old Vista partition and make it one big happy Win7 Hard Drive. And that's where the problems come in.
I'm trying to use Easeus Partition Master to do this and that might be the problem. There seems to be a problem with getting rid of the 1st, old partition. It won't let me do it. The only thing I can think of to do is "Merge", but that scares me because what if I render the HD unbootable and lose the value of all the time I've put into this thing, and lose all the data, too? So I don't want to try "Merge" unless someone that REALLY knows that they are doing tells me to. Easeus says the Vista (old) partition is the "D" drive, and is the "System" disk, while the Win7 (new) partition is the "Boot" drive. I guess. Both kind of sound the same to me, but whatever.
What *I* want to do is simply delete the old partition, and somehow "merge" it into the new. I just tried to use Paragon Partition Manager and had the same problem. I know I'm missing something simple here, but I don't want to trial and error in case the "error" is catastrophic.
