I try to resize third partition from 700 mb to all the rest, but fdisk don’t show me the message about ext4 signature, and after writing the changes board wont boot. I tried to use a lot of Several CD card.
[root@MSIarchlinux arch]# fdisk /dev/sdd
Welcome to fdisk (util-linux 2.41.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
