Let's say I have a dual boot on my computer with two linux versions and therefore two partitions on my hard drive.
Is there any potential negative effect from going back to a single boot system by removing one of the existing partitions and extending the remaining partition to the full disk? Especially on the disk itself (e.g. access speed) or performance.
What is happening on the disk when I repartition in this way? And has this anything to do with the filesystem?
