SSD + HHD PROBLEM

[TecH|ph]

Hi,

I bought Lenovo Legion Y520 laptop.
7th Gen Intel Core i7-7700HQ Processor (6 MB Cache, 2.8 GHz, 3.8 GHz max) 
Windows 10 Pro 64-bit 
NVIDIA® GeForce® GTX 1050 4GB GDDR5
8GB RAM, 2666 MHz DDR4
HDD / 2.5" wide, SATA 6.0Gb/s, 5400 RPM: 1TB

I bought an SSD(128GB, A-DATA XPG SX6000, M.2 2280, PCIe 3.0 x2 NVMe) 3 days ago, unplugged HDD, plugged SDD only, installed Windows 10 Pro 64-bit and everything is working perfectly, BIOS and windows are detecting the SDD.

When I plug HDD back, first boot is always good(no error, etc.), but whenever I restart my laptop its not booting from SSD(I have to restart my laptop twice because i'm getting "no bootble device, press any key to restart the machine" and again everything works fine, BIOS and windows is detecting the drive).

I tried to update SSD firmware with ADATA SSD toolbox but I'm getting "Firmware upgrade is not supported on IDE or RAID mode" but I dont understand that, because in BIOS, SATA controller is in "AHCI" mode.

Again, when SSD is plugged alone, its all good, but when I plug HDD it gets "no bootable device" error after every restart.

BIOS settings:
SATA controller= AHCI
Boot priority=Legacy + Legacy First
Secure boot= Disabled

 

SSD is first in boot priority, then hdd but sometimes after I get "no bootable device" error I restart laptop once more and go to BIOS and the SSD is not detected there, then I restart it once more and it boots normally with SSD.


And when it boots normally I go to BIOS once more and my HDD is before SSD in boot priority

Thank you, and I apologize because of my bad english.

Did you erase the hdd? Remove all the windows os files. I suggest you copy your important files onto your ssd, right click on the hdd to format it. This will take a while until the hdd is erased. Then paste your files back onto the hdd

I have formatted it few times, no luck.

you could try to prioritize boot disk in the bios, that way it would look at the SSd first and if it finds windows ( or other bootable os) it will stop looking for any other.

when formatting your only formatting a partition, but there is always a hidden partition that is not assigned a drive letter.

Usually this is the MBR, Master boot Record and contains the information of the OS.

In device manager make sure this partition is not there anymore.

Okay, MBR it is.

But how do I remove it?
 

EDIT: I did some research and figured it out.. and everything is working as it should be.

 

Thanks man?
