    Also, I did a test on the SSD. I got 700 MBs read, which is what other users also reported here. But write speed only 20-30 MBs?? So should I send it back? This doesn't seem right?

    Edit: Nevermind, tried 2 other ssd benchmark software and got about 850 MBs read max and about 700 write max.

    Does anyone know if there are any official drivers available from Samsung for this drive? Because I can only find drivers for the 950 pro nvme. Or will those also work?

    Hi, I can't recall anymore how I did the initial install of Windows 10, because since then I have always used the DISM tool to apply a windows image (WIM) I have created from the initial install.

    But there is just few possibilities which you can all try yourself.
    Either I have used the Ctrl+Shift+F10 trick to open a command prompt to start the UEFI shell and load the NVMe UEFI driver, before proceeding with the standard Windows 10 setup wizard.

    Or I have installed the Windows initially to the SATA SSD and used the DISM to create an image, I might have used some of the clone disk tools to copy it to the NVMe SSD too for example Paragons one is able to start the WinPE command prompt which can be used to start the UEFI shell.

    regards

    LH

    I have a HP Zbook 17 G2. I installed a Kingston M.2 240GB drive. I can see it in the BIOS and I can install Windows 10 x64 to it. But it says "No boot image found" when it reboots after the windows install. Iv'e searched and search this topic and changed BIOS settings about a thousand times as well.

    i read the page from 1to18, i am still confused what specific m2 ssd i should buy for my g2. recently i bought a sumsung pm951 256gb, it works in win7 and win10, but still unbootale, i tried eif startup, it seems too difficuluty for me. I wonder what modle of ssd is fit for this laptop, at least windows can boot from it without too much setup.

    i tried lenovo sl700, 2242, 2280, liton 2242, they are not detected, and the original sandisk a110 is not easy easy to buy in taobao, most of them are assemblled in tiny workshops, maybe unstable

    I know its old; who owns a Zbook 1x G2 anymore, right? :)

    But why do you all Hassle around with efi Stuff if you can Store it easy with Clover?

    You could just Boot say a normal Sata-SSD as your Bootloader having an Efi Partition for Clover. The rest of the Space would be used for Programs and stuff :)

    it would just redirect the boot-order to your NVME-SSD.

    Doing that right now and everything works perfectly as long as your m.2 is recognised in the HP EFI.

    PS: using a 960 evo right now. and a sata 840 pro for clover and stuff.(and a third SSD in the drive bay)

    A different thing though; wouldnt a 950 Pro work because of that legacy mode thing?

    Its a support for old boards that emulate non nvme for booting purposes...

    This thread is amazing, still alive since 2015. I have to attest that the EFI boot method described here really works. Yes, there are people who still use the G2 in 2018. There are not many 4th gen Haswell laptops with a m.2 slot. Most had the mSATA that was phased out. This G2 ver2 is the only one I found that has a m.2, even though it has only 2 lanes.

    I got this Zbook 15 G2 Ver 2 in eB for a bargain in 1/2018. The first thing I did was finding this thread to get the m.2 drive to boot successfully. The script on page 17 works great. Thanks to LH and Urr !

    Here is a quick summary:
    1. The generic NVMe driver described by LH on page 13 works on non-Turbo-Z drives. In fact I used a less expensive Toshiba XG4 x4 NVMe and worked. Yes, a single sided 2280 will fit right under the latch. Need to tape it down since cannot be screwed down (careful of the heat dissipation). No need to buy an expensive Sammy NVMe as this is only a 2 lane pcie2.0 m.2 slot that theoretical transfer limit at 1000MB/s Can only get about 840/450 MB/s R/W, but faster than a SSD. The same XG4 NVMe I run on a desktop 2500/1000 MB/s RW with a x4 lanes m.2 on Crystal Disk Mark.

    2. The script and the EFI NVMe driver must reside on your SATA EFI partition to load first as the G2 bios will not detect any boot drive in the pcie slot without loading NVMe driver first. Then use Urr’s suggestion to detect the NVMe drive by finding the dummy nvme.txt file and load the Windows bootloader from the selected NVMe. I had a working Win10 on the SATA HDD first and clone it onto the NVMe using Acronis.

    I am very happy that this worked out really well on the G2. Of course it is not as fast as my 7700 Z2-mini with 2400 DDR4. But this 4810mq G2 32GB 1600 DDR3 is not too shabby with the m.2 working and optimized with Throttlestop at 4gHz single core and 3.7GHz 4 cores! Hope this helps anyone else who still uses a G2.
    Using the script described in this thread is a lot simpler than using the Clover bootloader.

    First of all I'm greatful for this info and it's invaluable. Sadly though, if I had been aware of this same issue that affected the probook 6*0 G1 series with their m2 slot not booting windows natively, I would have reconsidered purchasing a used unit of this zbook. But since I have just bought it before being aware, no looking back...

    So if I comprehend correctly, I must also have another hdd/ssd with the nvme.txt bootloader file in order for the system to load windows from the nvme m2 ssd? (the same thing I had to do with the probook) Or after the initial boot and info "uploaded", can I boot windows without the other hdd/ssd inserted?

    Has anyone tried the Feb 2018 updated firmaware/BIOS from HP site? Can anyone confirm if this update fixed the m2 pcie boot issue?

    I can't download the NVMe driver from link. Can someone please upload it or send it to me please. Also can someone please write a clear and concise step-by-step guide with the file links as to complete this task, even for a newbie. Not everyone is at the same level of expertise and comprehension. Thanks!
