(solved) grug.cfg configuration fails

Question

when I try to configure the grub.cfg file I get an error message which says:
#grub-mkconfig -o /boot/grub/grub.cfg
generating grub.cfg...
found linux image:/boot/vmlinuz-linux...
found initrd image:/boot/initramfs-linux.img

[669.855533]SQUASHFS ERROR: can't find a SQUASHFS superblock on sda4

there are two HD and the partitions are as below:

I am trying to install Arch on /dev/sda5 the /home is on the partition /dev/sdb6
If I uninstall os-prober the configuration is well succeeded
Thanks

Cfr, thanks. Yes sda4 used to be the extended partition, please have a look what the fdisk -l output used to be:

Partition table entries are not in disk order
As the partition table entries were not in disk order, I tried to fix it with
fdisk /dev/sda
Command (m for help): x
Expert command (m for help): f
Expert command (m for help): w
after that, the new fdisk -l  output is
bash-4.2# fdisk -l

there is not the warning Partition table entries are not in disk order. However, I think I have made a mess
and here is the fstab:
