I have a new HP Omen laptop that I just installed a new 1 TB PCIe NVMe M.2 SSD hard drive.
The laptop came with a 128 GB PCIe NVMe M.2 SSD (which I swapped out) and a 1 TB 7200 RPM SATA HDD which I left alone.
I am a bit of a novice on this so I am confused with what to do next. Windows does not see the bigger drive and so it is all shown in Computer Managment as 'unallocated space'.
It seems to me on laptops where i had done something similar in the past I was just able to right click the main area, select 'extend' and follow the prompts.
However, extend is greyed-out when I try that? Help!
