More precisely, one cannot add another partition to a BIOS/MBR disk if 4 primaries already exist thereon, and none of those that exist is a valid Extended.
many people where confused because the OP said "UEFI" in his first post.
there is a bit more.
in msdos, AFAIK, extended partition (as the others) have to be in only one segment, it can't be split.
So, say that you use the 12Gb partition and remove it. These 12Gb are probably lost, if you want to use the 100+ Gb free space if the two are not contiguous.
Some software can move the remaining partitions (and renumber), leaving one space at the end. I think I saw the possibility of moving from primary to logical; but logical partitions need reserve a space for the pointer to the next partition, so there is a size difference to account for. -- Cheers / Saludos, Carlos E.
