Sparky sees internal hard drives as removal drives.

[Lassar]

I have just installed sparky linux.

Using sparky's file manager, shows my internal hard drive partitions in the media folder.

It show be in the /mnt folder instead.

The installer also does not handle booting right.

I had to use boot-repair to fix Sparklinux.

Is a way to handle the install so partitions are in the /mnt folder.

You can store/save all you external partitions manually in the /etc/fstab file so will be mounted where you need:
