I have two OS on my PC - linux and Windows 10 (upgraded from 8.1). MS created 3 primary partitions and the last one was used for linux. I have left some free space to have zone formatted in FAT32 or something to easly share files between those systems and some additional space to have in stock. I tried to format this free space, but I got information that the limit of primary partitions had been reached.
Is it possible to create logical partitions on this space instead of primary? And are those two small NTFS nessesary? I use grub as my boot, will something be wrong if I delete them?
