Trying to get win10 Enterprise running on a USB>NVME adapter. Copy to disc is about 3-4 minutes. R/W speeds under linux or native win are absurd. 4k R/W around 70-100/200-250MB/s.
Fire it over wintousb though, and it takes 30 minutes to boot on a high end machine. Meanwhile, If I just install Win7 to a USB (not using WintoUSB), first boot is about 10 seconds and the system is screamin'.

Once the Win10ent is booted (wintousb) I couldn't even bother to try getting anything installed to benchmark. Network is stupid fast, anything copying into RAM is fine. Disc IO however is pegged at 100% with a few KB/s. Just as a test, I did a PXE boot that ultimately lands over rs232 just for fun. Was still faster.

Did a quick RW test against the disc from Linux, and it's got no problem moving the data I expect.

What's going on here? I'm about to try a win7 via WintoUSB as well (just writing now).

Ah, P.S. Also tried on a decently fast USBFlash key. Same horrific speed. Even after it's gone through the first boot, subsequent boots are 15-20 minutes. This key gets around 150MBps, with around 50/150 4k rw. Essentially all the way to potato though with WintoUSB

Ah crap. P.P.S. I'm running WintoUSB in a win10 ent VM under linux. I suppose.... it's possible you guys are doing something funky with the disc because of this?

I am running a 2018 Mac mini with os Catalina. My VM software is parallels. I just upgraded my winto USB software.  I am trying to install windows 10 on to a Samsung X5 ssd. I can get as far a formatting the drive but that's where I get the error failed to run system API. I have attached my log file.
Please help..

Ola,

Quando eu tento fazer a clonagem de um HD para um SSD. Não consigo por falta de espaço!

Por exemplo: Tenho um HD que tem 200 GB ocupado e o SSD novo é de 240GB, na teoria a clonagem seria possível por que tem 40GB de diferença entre o HD e o SSD. Mas na pratica isso não acontece, o sistema diz que falta espaço.

Qual tamanho o HD atual pode ter ocupado?

At,

tried several USB sticks and 3 different laptops (all WIN7 64 prof), clone
process runs fine till very end (though very very slow, on USB2.0 port).

but when i try to use the stick for booting (same original laptop or one
of the other ones), i get a black-only screen with an error mssg ''This
Copy of Windows Is Not Genuine'' (or the german version '' Die Echtheit
dieser Windows-Kopie wurde nicht bestätigt '').

in all cases, the original is certainly MS-certified, in two cases the actual
version sold with the laptop. checked and doublechecked.

would appreciate your or users opinion on this, and any workarounds
possible.

i've been +using wintousb for a year now, and today i can't seem to boot, as there's a bcd error right after the manufacturer's logo. the error says "the boot configuration data file does not contain valid information" this was caused actually by me accidentally deleting my bcd via easybcd. i've tried rebuilding it through command prompt, but i get an error also that cannot find the path specified after using bootrec /rebuildbcd. any help would be appreciated.

You asked a user in another thread, "Is the Windows To Go USB drive a Legacy or VHD(X) mode Windows To Go?"  What if it is VHD(X) mode, which mine is?  The free Window to Go Upgrader v 2.9 doesn't show the VHDX on the USB drive in the GUI bars showing selection of boot and system drives, even if the VHDX is mounted with Disk Manager and assigned a drive letter. The end result of the check is an error message and the conclusion that it can't be upgraded.  Is it supposed to work in VHD(X) on USB WTG installations?

Hi!

I'm set up so that I can run three Windows 10 boot configurations on my Apple 2015 13" MacBook Pro:

• Booting from the internal Apple SSD's BOOTCAMP volume
  
• Booting from a WinToUSB clone of that volume on an external Seagate Barracuda 2TB HDD
  
• Booting from a WinToUSB clone of that volume on an external Sabrent NVMe M.2 1TB SSD
  

Hello,

I want to use WinToUSB to install a fresh Windows (Windows 10 Education 64 Bit) on my USB flash drive and to be able to upgrade this Windows installation with Windows To Go Upgrader. What are the required size of the USB flash drive? Are 32 GB sufficient? I would use the "clean up system files" feature of Windows before upgrading, because I know Windows needs a lot of disk space for temporary files.

Thanks in advance.
