Hardware Model: Predator PH315-54

Firmware Version: V1.15

I have 2 drives that I wish to use in my system. A 2.5 inch sata ssd by crucial and the stock 512GiB nvme m.2 ssd that comes with this craptop. After installing the drive the first time with my computer off, I noticed that it did not post, it would not let me into the bios or go to grub, it simply would not post and it gave no error code either, just a black screen. I then unplugged the drive and booted my system and it worked just fine. I then plugged the drive in, in the same way while the computer was running (Yes I know this can be dangerous but I don't ***** care) and the drive popped up like normal, and I could do r/w and anything else I wanted to. I rebooted to make sure it wasn't a fluke and it wasn't the system refused to post. I then uninstalled my main m.2 drive and it booted straight to uefi as the 2.5 inch drive had no os on it at the time. Why the ***** is this happening? Both drives work just fine just not together when booting? And they both run at the same time post boot. I should also note that when the 2.5 inch drive is connected over usb when booting, it posts just fine. The 2.5 inch drive now has windows to go on it, and the m.2 drive has my current Archlinux install (I swear if you ***** say anything about this being Linux's fault (which it isn't because it doesn't even post))

    Hey fake_name, Acer community is not ACER or the official Acer Tech Support in your country or any country, we are users of Acer products just like you that are on this forum asking about problems of our Acer products and are exchanging solution just like you, please don't write posts on this community with an abusive tone or be abusive, as we are here to help each other out😀 as I understand your frustration.

    Now, the symptoms that you are getting with your PH315-54 laptop could be because you are NOT connecting the 2.5" SATA drive FFC CABLE FOR HDD properly into its SATA mobo slot, as these laptops have a very awkward plug that has a top locking part that needs to lock into the bottom of the plug tightly and snuggly, so that it makes a 100% connection and both the SATA flat cable pins and the mobo plug pins, make 100% contact, otherwise the laptop will not boot and you will get the symptoms that you are getting.

    Try all this and get back to us, as and if the 2.5" drive is connected to the mobo SATA plug properly and 100% both M.2 with the Arch Linux and the 2.5" HDD with Win-11 24H2 version will work and boot 100%. Good luck.

    Note: I've had this same problem with a Nitro laptop 2.5" HDD and its SATA cable to the mobo SATA plug, so I know all the symptoms of what happens above, as its the same as in your Predator laptop below. Also, DO NOT connect M.2 SSD and 2.5" drives to the laptop when the battery and the adapter is plugged in or the laptop is powered on and the laptop has power, (you were lucky that nothing happened before) as you will damage the laptops power rail and/or its BQ or EC chips, which will be a major repair bill.

    Make sure that you are using this exact PH315-54 laptops Acer part number SATA cable below, as that is very important that its the right cable thickness, as if its too thick the mobo SATA plug will not lock the end of this cables pins into the mobo SATA plug properly and you will not have a proper connection.

    Below is a caption from your PH315-54 service guide of the mobo SATA plug, that has to make 100% connection with every pin of the FFC SATA HDD cable for the 2.5" drive to work and when booting for both M.2 SSD drive and the 2.5" SATA drive to allow the laptop to boot.
