Windows Booting Problem using M.2 SSD in ASUS X99-E WS

Stephen Ge · Oct 28, 2014

Hi everyone, I recently bought a ASUS X99-E WS motherboard and SAMSUNG XP941 512GB M.2 SSD, however when I tried to install Windows 7 into my SAMSUNG SSD, at selecting disk step, it says that

Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controllers are enabled in the computer's BIOS menu.

I can find the SSD in the BIOS booting menu, I enabled the CSM boot in BIOS, I also tried both IDE and AHCI settings, but the problem still exists. According to the comment left by one of amazon buyer of SAMSUNG XP941 512GB M.2 SSD that “this SSD can be booted in ASUS Rampage V x99….”

Can anyone help me with that?

did you upgrade your BIOS?

Stephen Ge · Oct 28, 2014

qazzi :

Yes, I have upgraded the BIOS to the latest version 0606

qazzi · Oct 28, 2014

what version of windows 7 are you running? updated?

Stephen Ge · Oct 28, 2014

qazzi :

Hi, the version is Windows 7 x64 Ultimate SP1

really wired i talked to a friend that used to own that kind of mobo. he said he never encounter that error. have you talked to asus tech support yet?

Stephen Ge · Oct 28, 2014

qazzi :

Hi, thak you for your replying, I had talked with ASUS tech support, they suggested:

Please enter the BIOS menu and under Sata configuration change the settings from
IDE to AHCI (or even backwards) to test. Additionally check if the SSD is recognized in
the BOOT menu. Under the same menu please select CSM boot -enabled. Save the
changes and retry.

very wierd problem. have you tried re installing while no HDD is connected except the SSD. (of course with AHCI and CSM enabled)

Did you try what someone said in a reply to your question??

Create a UEFI Win 7 x64 USB Install Disk with Rufus.

Google “create Win 7 UEFI USB” or try here:

RAID Driver:> - Get the latest f6flpy-x64 files for Intel RST and unzip them onto your USB Install Disk. This points to the latest (13.2.4.1000)

BIOS:> - Start with Optimized Defaults – in EZ Mode hit F5 or From Save & Exit choose Load Optimized defaults >

From the EZ Mode Screen go to Advanced Mode (F7)> - Under Advanced / PCH Storage Configuration – Set SATA mode to RAID (Install needs to see this in BIOS, it can be changed later. The drive comes up as AHCI in Device Manager)> -

Under Boot:> - SATA Support make sure this is “All Devices” or Windows will not restart correctly if you have any other drive connected.>

Disable Secure Boot (Windows 7 does not support secure boot)> - Clear Secure Boot Keys> -

Set OS Type to [Other Device]> - Enable CSM> - Boot Device Control —> UEFI Only> - Boot from Network Devices —> Ignore>

Boot from Storage Devices —> UEFI driver first> - Boot from PCI-E/PCI Expansion Devices —> UEFI Driver First>

>Boot your USB Disk:> -

Hit F8 to bring up the boot menu or under EZ Mode hit Boot Menu (F8).> -

There will be two lines for your boot disk. The device to boot from will have “UEFI:” in front of the device. (Example: UEFI: Kingston Data Traveler 2.0 Media)> >Get all the way to the Install to Disk screen. I assume you know how to get there… ( This part is from memory so forgive me if the details aren’t quite exact.)

At the install disk screen hit the driver option and install the x64 version of the Intel RAID driver from the f6flp-x64 directory on your USB key

The XP941 should show up in the drive options. I believe at this point you should see 3 partitions. You are creating a GUID partition disk.> -Format the primary partition. It should be ~488G.

At this point you should be able to install Windows to the primary partition and go about your merry way.

Someone here said something similar

Bought this drive for a new 5960 Asus X99 build. Had to search all over he** and back to figure out how to install Windows 7 X64 on this thing. Needed to make a special Win7 GPT partition bootable USB key and set the right parameters in the BIOS to boot in UEFI mode.

Once this was correctly configured and Windows was installed now the drive reads and writes around a 1 Gig a second!

I kept trying to find the MBR hook in the BIOS to show that the drive was connected and working. Turns out that is not how UEFI works as it is BIOS independent.

No need for the BIOS to find the boot sector on the drive and hand control to the os. I may not being saying this correctly, but it is bootable.

Hi, qazzi and Paul NZ, thank you for your replying, yesterday I had successfully installed the Windows 8.1 Pro x64 into my Samsung SSD using DVD, the followings are what I did, some of those steps maybe unnecessary:

1. I disconnect everything from motherboard except CPU, memory, graphic card and M.2 SSD.
2. In Bios, restore all settings to default.
3. Change SATA mode to IDE in PCH Storage Configuration under Advanced.
4. SATA Support: All Devices
5. Enable CSM and set

Boot Device Control: UEFI and Lagacy OPROM
Boot from Storage Devices: Legacy Only
Boot from Network Devices: Legacy Only
Boot from PCI-E/PCI Expansion Devices: UEFI Driver First

6. Disable Secure Boot (Set to Other OS)
7. Set Booting order: 1st SAMSUNG M.2 SSD, 2nd DVD-ROM
8. Install Windows 8.1, at selecting disk step, at drive option, delete any partition of M.2 SSD.

After all above steps, the warning

Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controllers are enabled in the computer's BIOS menu.

Finally disappears

After I installed the Windows 8.1, I connected all hardware back to my machine, changed SATA mode back to AHCI in PCH Storage and re-enable the Secure Boot.

Question: I am thinking of buying the same Asus MB and M.2 SSD (except 256Gb). What are the Data Transfer Rates you are getting from this setup? I know at one point, you were only getting 1Gb/s, which would not make sense for me to go M.2. Thank you in advance for your help. Best Regards, Nat

Thank you !

How can we do the same on a none UEFI system? Can't get it to show up using a ZTC PCIe M.2 PCIe card with a Samsung SM951 256GB AHCI MZHPV256HDGL-00000 M.2 80mm PCIe 3.0 x4 SSD - OEM....

Running on Supermicro none uefi x8 something or other...

It shows up in Diskpart in Windows Setup just not in Boot Menu...?

Worked for me using a asrock z97 extreme6 and a Samsung SM951 128GB AHCI MZHPV128HDGM-00000 M.2 80mm PCIe 3.0 x4 SSD
