    No problem with mu Mint system on the stick. That sees and you can use the second partition.

    I have limited experience in this area so i'll bow out and leave it to those that know what's up.

    You want to avoid an "external" storage device as they too are sometimes flagged as removable..

    So you want an "internal" device in an external adapter..
    Thanks KYHI, that's good to know!

    Cool video! Are you the author? I have to try Linux, it's one of my pending homework. Good to know that that cheap PNY stick has good performance. Would this stick have a much higher performance than the PNY? Is the price difference justified?

    @antares, Yes I am the author of the video. I have that SanDisk Extreme also but as a 65GB model. I cannot tell the difference in performance compared to that 128GB PNY. The PNY access time is 0.7ms and the SanDisk is 0.3ms. So there is a little difference but it's marginal. The data transfer rates are the same. Here are the measurements of both:

    Thanks Wolfgang. So then why pay $80 more for a stick that offers the same capacity and only a marginal performance improvement? Sounds like a ripoff.
    Also, you measured the Sandisk to have an access time more than twice faster than that of PNY, and yet you call it marginal? Is it because in practice it's not noticeable?
    Also, how does a Windows 8 in a VM (like Vmware) compare to Windows 8 in a to go USB3 stick in terms of performance?

    Marginal in the effect that it has. Yes 0.3ms is better than 0.7ms, but in real life I hardly noticed any difference. If you use VMware, there is of course a certain overhead.. I never really compared the performance of those two. It will largely depend from which medium you run the virtual system (HDD, SSHD, SSD or stick). I have run VMware Player virtual systems from all of those and the SSD is obviously king.

    You can also install a Windows to go on a SSD. Then you enjoy the best of all worlds if you run it from eSata - USB3 depends on the mobo implementation. Some are faster than others. I just recently saw a friend's new HP desktop run a 1000MB/sec with Macrium imaging. On my older XPS 8300 that is only 500MB/sec. Same program and same disk only difference is W8.1 versus W7 but the W7 machine has more RAM (8GB versus 4GB) and a much faster CPU (i7 versus i3). It was still slower.

    Windows 10


    I attempted to follow these instructions to create a Windows 8 flash drive, but am sort of 'stuck' at the bcdboot step. I am running Windows 10 as my host OS. I'm not necessarily asking for support as I fully expect this to work using a Windows 8 host. Just wanted to share my experience.

    The "bcdboot F:\windows /s F: /f ALL" step fails, just spitting out the help text for bcdedit. There is no /f option listed. I tried simply omitting that option to see what would happen, which left be with "bcdboot F:\Windows /s F:" which returns an error: "BFSVC: Failed to create a new system store. Status = [c000003a]"

    bcdboot F:\windows

    /s = the partition to create the boot files

    bcdboot F:\windows /s F:

    tells bcdboot to put boot file on F:

    /f = firmware type

    bcdboot F;\windows /s F: /f ALL

    ALL firmware boot files
    UEFI firmware boot files
    BIOS firmware boot files

    Thank you. Here is the help text from both versions.

    Windows 10:
    Bcdboot - Bcd boot file creation and repair tool.

    The bcdboot.exe command-line tool is used to copy critical boot files to the
    system partition and to create a new system BCD store.

    bcdboot <source> [/l <locale>] [/s <volume-letter>] [/v]
    [/m [{OS Loader ID}]]

    source Specifies the location of the windows system root.

    /l Specifies an optional locale parameter to use when
    initializing the BCD store. The default is US English.

    /s Specifies an optional volume letter parameter to designate
    the target system partition where boot environment files are
    copied. The default is the system partition identified by
    the firmware.

    /v Enables verbose mode.

    /m If an OS loader GUID is provided, this option merges the
    given loader object with the system template to produce a
    bootable entry. Otherwise, only global objects are merged.


    Examples: bcdboot c:\windows /l en-us
    bcdboot c:\windows /s h:
    bcdboot c:\windows /m {d58d10c6-df53-11dc-878f-00064f4f4e08}
    Windows 8:
    Bcdboot - Bcd boot file creation and repair tool.

    The bcdboot.exe command-line tool is used to copy critical boot files to the
    system partition and to create a new system BCD store.

    bcdboot <source> [/l <locale>] [/s <volume-letter> [/f <firmware>]] [/v]
    [/m [{OS Loader ID}]] [/addlast]

    source Specifies the location of the windows system root.

    /l Specifies an optional locale parameter to use when
    initializing the BCD store. The default is US English.

    /s Specifies an optional volume letter parameter to designate
    the target system partition where boot environment files are
    copied. The default is the system partition identified by
    the firmware.

    /v Enables verbose mode.

    /m If an OS loader GUID is provided, this option merges the
    given loader object with the system template to produce a
    bootable entry. Otherwise, only global objects are merged.

    /d Specifies that the existing default windows boot entry
    should be preserved.

    /f Used with the /s command, specifies the firmware type of the
    target system partition. Options for <firmware> are 'UEFI',
    'BIOS', or 'ALL'.

    /addlast Specifies that the windows boot manager firmware entry
    should be added last. The default behavior is to add it
    first.

    Examples: bcdboot c:\windows /l en-us
    bcdboot c:\windows /s h:
    bcdboot c:\windows /s h: /f UEFI
    bcdboot c:\windows /m {d58d10c6-df53-11dc-878f-00064f4f4e08}
    bcdboot c:\windows /d /addlast]
    So it appears the version bundled with 10 omits the /f option entirely.
