    MCT not functional. Making USB Install, Copy ISO content?


    I referred to this thread from April: Use MCT to create bootable Flash drive with previously downloaded ISO
    Post #2 from Bree looks really simple - so simple I'd be amazed. The first thing is to use 'Disk Management' to mark the USB device "active" according to Bree. AFAIK, and just tried it, Disk Management disallows that very thing. It can only allow one active Partition on the system. Right? So the option is grayed out. Perhaps Bree meant to say Diskpart. I used Minitool to get that done. Marked Active/Apply.

    Then Following Bree's advice, I double click .iso and move/copy all content to the USB device, and done.

    Right?

    As long as the partition is Fat32 and active, that's all there is to it.

    If you do it via diskpart, not disk management, it will work and let you mark it as active. I've done it that way many many times. It's my perfered method for creating my install media. I have the VL ISO that the MCT won't give me that I use to install Enterprise. I can make multiple bootable thumb drives with just the one download using diskpart.

    I'm sure you're both right now. Add Minitool Partition Wizard to that shortlist. No issue at all.
    I might further add, for the future reader, that one should unhide "Protected OS" files, then copy the contents of the .iso to the Active marked partition on the USB device. For me, working with a late model Dell Latitude, the install went smoothly by selecting the named USB UEFI device. Once Win 10 was installed, I had to return to the setup menu and mark it to boot from the UEFI category Windows Boot Manager. I note this last step is often left unstated, keeping threads alive via confusion

    I'm baffled at the many laborious tutorials on how to get this done... It is really simple. And it is embarrassing that Microsoft put MCT out there with the install routine in a sorry dysfunctional state, sending users scrambling for these many tutorials and patchwork threads. The ISO download utility works fine - it should, being so simple, but the install-now util is buggy. Past versions worked well, but the current one is awful

    The MCT works just fine? If you select the option to make a bootable thumb drive it will do it for you. And that drive will work for UEFI and or Legacy BIOS. The diskpart procedure will also give you install media that works with UEFI and Legacy BIOS. I've done both myself, just to verify it works.
    The one thing they do need to fix, or make better, is the downloading of the required files. You shouldn't have to download them "again" to get the ISO and then make bootable media. It just waists time and band width. It should have an option to create install media from the ISO, or be smart enough to know it already has all the files cached.

    there are hundreds of threads on the topic on the web, and quite a few here on tenf. It isn't reliable. congrats if it worked on your particular project. I have half a dozen win10 systems working well, different makers and configs, and it failed universally, trying it with the same exact USB device I had used previously with the old version with no issues, as well as with others - sd card, sticks, etc - and manually cleaning it and formatting it [I note the older MCT didn't need manual intervention - it did a stellar job of clean and reformat]. such a waste of time and energy even for skilled people... more hopeless for the novices FOR WHOM the thing appears to have been published in the first place [the tech people didn't need it].
    I agree with your suggestion.

    Edit: P.S. this is just one of hundreds, but it well illustrates the lunacy. Simple need, simple solution, does not work. So the issues balloons and fractures into a bunch of workaround ideas, cluttering the forum, cluttering the tech-help side of the web.... on and on. We could pick three code guys at random from tenforums and have it solved by nightfall. inexcusable

    I usually only ever run it once to create one thumb drive. Then test that on at least one PC. I have a My Visual Studio Subscription and prefer to get my ISO's from there. Then make my thumb drives via diskpart. I don't remember ever having any issues with the MCT other than it being time consuming to use. I'm not saying its flawless, just that It's been reliable for me as near as I can remember anyway.

    The USB needs an MBR partition layout for Disk Management to be able to set it as Active. I did mention in post #2 that...

    A few USBs are partitioned in a way that doesn't allow you to mark it as active. If so, use Diskpart to prepare the USB...
    ...also, if you've used Rufus (or similar) to format the USB as GPT then you'll need to use Diskpart (or MiniTool Partition Wizard) to make it MBR and Active.

    I've never had a problem making a USB from the MCT. However, if you try to use the MCT with a USB that's formatted as GPT it will fail.

    Ah, OK, will have to try and remember that one.
