I had a hard with two partitions. I deleted the first one and extended the second one using that space.
When doing so windows warned me that it will be converted from standard to dynamic disk and i won't be able to boot any OS from any of the volumes.
In disk management i still see both partitions as separate ones, they are just both the same letter and in windows explorer appear as one with the full size.
I'm ok with all that, but do i have any performance (or other) loss?
Would it have been better to backup the data, format and make the disk one real partition and return the data?
