Trying dual boot..... my pc won't see one of the SSD's... HALP (=TT^TT=)

[TigressGrid]

So I decided to re install windows back into my life, just for gaming and drawing. how ever this is the issue I ran into.

 

My pc has a 250GB SanDisk SSD (Linux Mint), 1TG HDD (for storage) and I just integrated a NVMe for windows. my MOBO is Asus ROG B450-F 

 

I was able to use my Linux drive very normal, but once I install the NVMe the BIOS no longer sees the SanDisk SSD drive. I haven't even put Windows on the NVMe and the BIOS only sees the NVMe and the HDD. I am wondering if I am doing something wrong, or what configurations do I have to change. the part that throughs me off is that there is nothing on the NVMe and the MOBO just sees that and the HDD and once I remove the NVMe the pc sees my SanDisk SSD.

I’ve been seeing repetitive issues with bios and NVMEs in posts.  I don’t know what the deal is.  Good chance someone does but it’s not me.  There used to be a thing when they added SATA where it was sort of an addendum to the code and would get messed up occasionally.  NVME has been around for a long time though.  Could be a motherboard specific issue if it’s bios.  Generic advice for anything BIOS is clear CMOS and maybe reflash.  I don’t know if either would help or is needed though.

Try changing the SATA port that the SSD is on, for example: If it's on port 5 or 6, switch it to 1 or 2. A lot of motherboards disable SATA slots 5 and 6 when a NVME drive is present because it requires those PCIe lanes.

Well could be a few things, bios update being 1, or somehow bios see both the nvme and sad on the same I/O and simply. picking NVME as the king, out of curiosity which drive is loaded with Linux and windows,

I have been thinking about it, I will have to try this. is worth a shot. But even then wouldn't I need to change also some configurations on the boot settings tho?

No, the slots are disabled by the motherboard automatically if that's the case of why the SSD isn't showing up. A simple change of the port it's plugged into on the motherboard is all that's required, as long as it isn't 5 or 6.

Just perused through your Mobo manual and yes, SATA slots 5 & 6 are disabled when a NVME drive is present. Seeing that the drive disappears when you install the NVME drive, I'd assume this is your issue. Just ensure you plug the SATA SSD into a slot other than 5 or 6. 

 

EDIT: You can go into your BIOS to disable that feature, which then limits the NVME drive to a x2 PCIe lane(instead of x4). It's found inside the "Onboard Devices Configuration" menu, under the "M.2_1 control" option.

Nice guess I was slightly correct that they were sharing an I/O basically just it's more the hardware then bios great job happy for ya
