[SOLVED] Grub won't detect Windows10

I'm really new to Arch, I tried to dual boot arch but windows won't come up in grub. I may know why. I got two EFI partitions and I don't know if that is why it won't show up so I wanted to ask you guys if that can cause the problem so I don't just waste a lot of time fixing something that doesn't need to be fixed. Otherwise I could use some help.

My fdisk -l log:

Re: [SOLVED] Grub won't detect Windows10

Does os-prober detect your Windows 10 after mounting the drive?
Have you installed the package in the first place?

If you haven't already, give this step a read.

Re: [SOLVED] Grub won't detect Windows10

I see that you have a Kingston A2000 nvme SSD.

Please read NVMe SSD I/O errors, not sure if hardware failure carefully.

It has nothing to do with you current problem (sorry), but it will help you later on.

Yeah I forgot about os-prober, I did had it installed but never mounted windows! Thanks it works now (:
I will have a look at that harddrive thing! (:
