First I tried fdisk, I tried
fdisk /dev/sdb
linux is installed in this ssd
then I hit 'n' and it says: all space for primary partition is in use And I can't do anything after that.
Then I opened gparted and tried to create a new partition that way, and the new partition option is grayed out.
I'm running from boot media, because I heard you can't edit partition while it's mounted.
I have no efi partition from my previous windows installation. And I can't boot Xubuntu without a bootloader The ssd is MBR. Can I create an efi partition on my HDD, a separate hard drive and will it work from there? Because I'm able to create new partitions from the hdd. But oddly not from ssd why?
