i m trying to create an uefi boot usb with windows 8.1 with WinToUSB, but i dont understand how the software works, so i hope someone can help me with

i use windows 7 pro x64 with wintousb 2.1 and 2.2, both without luck

im trying to install windows 8.1 pro on an usb stick (uefi bootable)

so i open
- wintousb
- select my windows 8.1 iso
- click next
- select my usb drive 32gb (i assume it will ask me for uefi bootable or bios bootable??? but i didnt)
- wintousb format my usb stick, without asking uefi or bios or both bootable? (do i need to do something about it myself?)
- wintousb installing, but the stick does not work?


i saw this in the manual:

• Booting UEFI-based computers: Covert the USB drive to GPT partition scheme and create the EFI system partition (ESP) and boot partition. The EFI system partition must be FAT32 format and the boot partition must be NTFS format.
  
  
  

2.2 Beta, the "Cancel" button stays grayed out and I have to use the Task Manager to kill the process.

Also, Bitdefender has to be turned off or else it will quarantine many files during the build.

Could the following be a workaround for the Windows USB 3.0 port booting limitation for a cloned copy of Windows 7? https://www.youtube.com/watch?v=yd37BJwTxiM I am probably overlooking some technicality when it comes to mounting etc. when it comes to using WinToUSB Clone process.

Thanks

Hello everyone. I have a quick question: If i'm using Windows 10 Build 10074 on a 128 GB Sandisk ExtremePro ( created with VHD mode ), Will I be able to upgrade the build (to 10122)  without problems ?
Thank you

I have just bought a Sandisk Extreme USB 3.0 64G SDCZ80-064G to install Windows 8.1 Pro.
I have tried with with WinToUSB V2.1 and with the patched VHD version, and there is no way to boot neither on my PC (Samsung NP740U3E-A01FR), nor on other PC (Example NUC Intel i5).

Could you give me some advice ?
Do I have to format the USB key first ?
-GPT or MBR ?
-FAT32 or NTFS ?
-create 2 partitions ?

Do I have to run WinToUSB on legacy mode or VHD mode (I have tried both, VHD with 32Go) ?

Thanks for your help.

Hello,

I'm running Windows 10 technical preview on a tablet and wanted to use EasyUEFI.

However upon starting I get an error:

The system cannot read from the specified device (0x0001006200A50000).

According to msinfo32 BIOS mode is UEFI

Any idea how I can resolve this?

Thank you!

Apologies in advance if this has been addressed already but I did search and didnt see any relevant posts.

I am attempting to clone my existing windows 7 enterprise install to an external USB drive and it repeatedly fails [System Clone was not successfull] with the above error.

I was able to open a command prompt and verify that both disks are visible [diskpart; list disk]

I noticed after each failed attempt, the destination disk ends up in "unallocated" [partitions wiped out] state and the tool wouldnt accept a blank/unformatted destination disk.

Any help would be greatly appreciated.

Trying to to get windows 7 on my usb. First try looked like it works, till my pc turned off on his own. Now i wanted to try it again, but I get the error on the Second attachment.

First Attachment appears when i start WinToUSB (before the actual programm starts), the second when i try to format my flash drive.

Hope you can help me. If you need more info just write.

€dit: For those who got the same problem, just Format your Stick to FAT-32 and then let WinToUSB Format it.

Norton wont let me download wintousb (either 2.0 or 2.1 beta) claiming file is infected with suspicious.cloud.9 trojan horse virus.
Can anybody confirm this is true or false?

WARNING: The Sandisk Extreme disk as recommended is now set up as a removable disk not a fixed disk, and so cannot be used for EUFI.    You can still use it in legacy BIOS mode.

 I was sceptical of its speed claims, but on a website, it said if you are copying from/to an SSD drive via USB3, then you can get close to the maximum speeds claimed 100 MB(ytes)/s write, and 245 MB/S read.

I tried it on my laptop which has an ssd as main drive, and I got 98.5 MB/s read and 210 MB/S read i.e. pretty close to claims.  The USB does get pretty warm though - I wonder about long term usage of this.
