I cant install High sierra because disk is not shown and when I go to Disk Utility It says Disk Is Uninitialized. When I try to erase it, it says unable to write to the last block of the device. I had Lion running in the same disk before (and computer) but now the disk is empty but has no partitions. I tried to create a partition with gparted but It still had the same problem.
