    If I install Windows 7 with Daz Loader I realize that will require me to install in legacy / non-UEFI mode. Say I later want to change it to Windows 10 using the clean install method (tenforums.com/tutorials/23354-clean-install-windows-10-directly-without-having-upgrade-first.html), with the caveat of UEFI boot/mode. I transfer my saved GenuineTicket.xml file over.

    1) Will this work or am I forced to stick with legacy / non-UEFI mode with regards to Windows 10?
    2) Will my Windows 10 remain activated/genuine?

    Edit: I found most of the answers from here: forums.mydigitallife.net/threads/28669-Microsoft-Toolkit-Official-KMS-Solution-for-Microsoft-Products/page331?p=1106759&viewfull=1#post1106759. It looks like it is possible, however this forum member did the typical upgrade method, not the clean install method. I'd prefer to save time and effort to not have to upgrade then re-install Windows 10 (as I also want to start refresh) because that'll be like 3 installs in total.

    Thanks

    SOYA : sorry, I forgot to run this scenario when doing activation install test. Win 10 has been strange where some people have had methods fail where others have worked for different people.

    Either way you will need to do the skip upgrade trick so just save the XML. Try doing it using UEFI, then wait and see if it activates. If you get any any activation errors you can always change the windows 10 to a Volume license buy adding the generic key later, then you can activate it and then switch it back to a activated retail, which I have done and it worked.

    So don't be shy, go ahead and try it, and please post how it goes.

    I don't think the partitioning scheme matters.

    So I would say yes to both questions.

    partition scheme does not matter. you can install windows 7 in legacy mode and use daz loader then get the genuineticket.xml and then use that to install windows 10 using uefi.

    Your edit is about the use of a kms solution. The use of genuineticket.xml is about a genuine solution.

    Thanks for the answers :). This won't happen until next month at the earliest as I'm planning to do this on a new desktop, waiting for the new Intel Skylake I3s to come out in Canada.

    Smart person, the Z100 series is awesome. Skylake is no big deal but the chipset is.

    Maybe not so smart o_O. I just researched that Skylake removes EHCI (USB 2.0) driver support on Windows 7. And Windows 7 doesn't support USB 3.0, so this complicates matters.

    Then get a ASrock board, has instructions on how to install with USB mouse an keyboard, and has Intel USB 3.0, and there are win 7 drivers, actually win 7 is the only one that's needs a seperate driver, because with 8 and 10, the driver is installed by Intel chipset INF installer.

    You really don't need just a ASrock board.

    Apparently there are workarounds from other mobo manufacturers like ASUS: rog.asus.com/forum/showthread.php?74220-Windows-7-Install-quot-A-required-CD-DVD-drive-device-driver-is-missing-quot
    Luckily my next PC will include a DVD drive, but my future PC won't, so I'll have to research alternative solutions like modifying the Windows 7 ISO by injecting with USB 3.0 drivers, etc.

    I just posted that above, you can use USB 2.0 and install with a ASock and Gig board, using a USB mouse, keyboard, flash drive. You can also install win 8 and downgrade, I think, haven't tried it. LOL

    Yes it can be done, this is the easiest way, a little bit homebrew but it works:

    You can get a win 8.1 or 10 iso, extract it to a FAT32 formatted usb drive, remove/delete the 8.1/10 wim file and put in the wim file from your 7 installdisk and your win 7 will install from usb3.

    EDIT: My mistake, my workaround is meant to use if you want to install 7 using an usb3 port :)

    If it's just to activate w10 later, the easiest way is

    Shrink the partition using the actual OS, deploy the w7 image with dism /Apply-Image or imagex /apply on anew partition, add the item to the bootloader using easybcd, reboot in 7.

    Once finished, delete the W7 partition, and enlarge the old one.

    Almost zero time w/o a working pc. Superfast installation, no usb troubles, no pendrive or dvd involved, no keys to type, and so on.

    Judging on the basic knowledge shown by the OP that whas the easiest way but it doesn't solve his problem that the new cpu's don't support usb2 anymore (which i cannot believe but it was his comment, not mine ;) ).

    That's an interesting method. Although I'm not confident as I don't know whether it'll be safe and I haven't seen this mentioned elsewhere simply by replacing the WIM file. e.g. What if the other files in the ISO doesn't recognize or other missing interactions with the WIM file.

    I'll go for the ASRock USB ISO modification method: asrock.com/microsite/Win7Install/index.html


    lmgtfy.com/?q=skylake+windows+7+ehci+usb Of course they do, but not quite for Windows 7 unless one goes with one of the workarounds to load and install the USB drivers prior to Windows 7 being installed. People have reported that even with a DVD drive they cannot use their USB keyboards/mice, but I think that can be worked around by switching to Legacy mode in the BIOS/UEFI
