Asus Laptop Replaced SSD Cant Boot Windows After Install

xboxhaxorz · 24 Nov 2018

I put a new samsung 970 pro mvme ssd into my laptop with a windows 10 usb drive, it recognized the drive and copied files, but at restart it booted back into the USB

I removed it and it just keeps booting to the bios, i have secure boot off and csm enabled
I cant delete boot option as its empty

I booted back from the USB and it did indeed create all the partitions for windows, i deleted and resinstalled with same issue

What did you create the Windows 10 USB flash drive with and why is CSM enabled?

The media creation tool, i have used the same drive on another pc and it worked fine

Well when i checked the bios csm was enabled, i tried disabling it with no change

When you say you put a new NVMe SSD drive in your laptop, was that to replace an old SSD? Was the laptop booting from an NVMe SSD before? And what is the exact model of Asus Laptop?

Asus NX500, yes it was working fine it comes stock with an nvme ssd
Original ssd is samsung mzhpv512hdgl
I made a new usb drive and same thing, put my old ssd back in and it boots to windows

So the original hdd appears to be an m2 PCIe and the new 970 pro is m2 mvne

When you boot from the USB flash drive, press shift+F10 to open a command prompt window. Run:

diskpart
list disk
select drive 0 <-drive 0 should be the installed SSD. If it isn't the installed SSD, then change the 0 to the correct number
clean
exit
exit

Then proceed with the install. After selecting Custom Install option, on the next screen, highlight the unallocated space and click next.

I believe all PCIe M.2 SSDs are NVMe, but I might be mistaken. Is there a part number/model number on the original SSD?

EDIT: I am mistaken. Not all PCIe 3.0x4 SSDs are NVMe. The original SSD in the computer was NOT NVMe.

I am trying that now

Original ssd is samsung mzhpv512hdgl

Apparently some are pcie and some are nvme

I went into the bios and under advanced it lists sata information with no drives listed, when i put the original ssd back in that changes to pcie ssd information and it lists the ssd there

So i am thinking the bios is not compatible with the nvme drive but if that is the case why does it get recognized in the windows installer?

I believe your mzhpv512hdgl is an NVME SSD

This is a sata based M.2

This is an NVME SSD

Both are M.2 designs and can look quite similar.

Your Samsung SM951 drive is supposed to be NVME. (It's also PCI-E X4.) I think that all NVME M.2 drives are PCI-E, but not all PCI-E M.2 drives support NVME. (I have an oldish Plextor M.2 drive that is not NVME. It's also PCI-E X2.)

This doesn't really help you, but it's a data point.
