SSD upgrade for HP Omen 15-ce008nq:

[briinZ]

Hey there! So I have come back after few months and I did the upgrade of RAM as suggested in this thread . However, now I want to make an SSD upgrade and I don't know which one should I choose and if its fitted for my laptop or not. Until now I have found two SSDs which I consider to buy:

HP EX900 M.2 250GB PCIe 3.0 x4 NVMe 

or

Kingston 250GB A2000 M.2 2280 Nvme PCIe 

(these I found available in my country for a price of around 47$)

Could you please help me pick the right one in terms of compatibility with my laptop and performance?

LAPTOP INFO:

Product number: 2KF69EA#AKE

CPU: i7-7700HQ

GPU: GTX 1050 2GB

Either one should work fine.

So PCIe is compatible with my laptop? I saw that there are different types of M2 SSDs, such as SATA3 (ADATA Ultimate SU650 for example). In the photos I saw that SSD SATA3 pins are different than the PCIe ones and I am curious which of the two are working on my laptop.

The pins do not matter. All M.2s will fit in an M.2 port. SATAs tend to be B + M keyed and NVME tend to be M keyed but that is not universal. Your laptop will accept either a SATA or PCIe/NVME M.2 2280 form factor SSD.

So I have done the SSD upgrade on my laptop and it works fine. Despite this, I have stumbled across problems when I tried to install Windows on the SSD, but I managed to do it so only after I took the HDD out, let the SSD alone, installed the windows on it, and then plugged in back the HDD. 

However, now I have another problem which bothers me. Whenever I want to start up the PC, I have to manually choose the SSD as my booting device (through F9), if not, the PC will boot automatically from the HDD. I have tried to change the order in BIOS but there's no such option to choose the SSD, it only shows - OS booting device, USB, etc.  In my disk management partition, I have three local disks: C = is the SSD which the new Windows is installed; D = contains the old windows (which doesn't run, when I want to boot from it, it goes on to repair mode but no solution is found) E = is my storage partition from the HDD. But I see that there are three partitions with about ~600 MB and I think that Disk 1 partition 4 is the one that wants to automatically boot from the old windows. Is there a solution to fix this and the PC to boot from the SSD on its own? I have been thinking of deleting the old D partition (where was the old Windows) and attribute the remaining space to E.

Yes you probably still have boot files on the hard drive. You want to remove them as you suggest.
