I first had Windows 8.1 on my laptop installed and now I'm trying to add Ubuntu 15.10 and be able to dual boot. I have freed up some space and partitioned my hard drive for the Ubuntu installation.
Windows shows:
C:/ - 100GB (Windows 8 installation)
E:/ - 430~GB
F:/ - 430~GB
when I run the Ubuntu installer, it shows these:
/dev/sda1 - 1 MB (usage: unknown)
/dev/sda2 - 104 MB (usage: unknown)
/dev/sda3 - 105'549 MB (usage: unknown)
/dev/sda4 - 894'548 MB (usage 0 MB)
Even the usage is wrong as I only have the F:/ disk completely empty which is around 430 GB, the rest is used up mostly
I tried running
sudo gdisk -l /dev/sda
which returns:
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: not present
*************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format in memory.

This doesn't change anything though, what can I do?
