Trying to install Windows 8.1 on a USB 3 SSD external drive. When I get to the destination, WinToUSB sees the drive and I select it. It shows 2 partitions- 1 small and the other about 110GB. But I can't actually select them and the Next button is greyed out. Any idea what the problem is?

I should add that I was doing this on a Parallels VM on a Mac, also running Windows 8.1 But I don't think that should matter since everything is there. My intent is to make a bootable drive so that I can boot the Mac into Windows without taking up precious internal SSD space (I'll install the Bootcamp drivers onto the external drive later).

Hi all,

I've just started playing around with this great tool and have a question. If I choose a Windows 7 RTM ISO as the source when installing to a USB, I get the option to use either legacy or VHD mode. If I choose a Windows 7 with SP1 integrated ISO as the source when installing to a USB, the VHD option is greyed out.

Is this because of a limitation of installing to USB with a Windows 7 with SP1 integrated ISO, or is there something else I can do to get the option to use VHD in this situation?

Cheers,

Hello. I just made a 64bit Windows 10 Insider preview USB HDD. I installed it using WinToUsb, and I formatted the drive for both UEFI and BIOS - machines. I completed the installation in my laptop, and it works perfectly and smooth.  But when I tried to move the HDD to my older PC, it doesn't boot. It tries to load W10 for a while, displaying the Windows Logo, then screen goes black and 2 seconds after that the PC reboots. Then it tries to load startup repair for a while, but after that the same happens. It works perfectly in my laptop. The laptop has Pentium, 4GB DDR3-1366 (one module), and integrated graphics. The PC is a little older, it has Core 2 Quad Q6600, 4GB DDR2-667 (one module), Nvidia Geforce GT 640. I tried changing BIOS settings for the PC, but "load optimized defaults" didn't make any difference, and "load fail-safe defaults" just made it slower. Do I have to install some drivers for the another PC to make it to work or what? There is no BSOD or anything, it just reboots. BTW, the laptop has a broken SATA Controller, so that's why I have to use WinToGo. The PC is fine. It runs Windows Vista perfectly. (It is 32-bit, but the CPU supports 64-bit, as it works with 64-bit Ubuntu.)

Hi everyone,

I have another system with Windows 8.1 running on USB just fine but right now I am trying to do Windows 10. I tired in the past with build 10074 and it would go but it would just be stuck at the boot screen.

I have a different drive now (Install SSD 80 GB) that I want to put windows 10 on to have and show people what windows 10 will be like but I get that error every time.

Is it the ISO, SSD, or maybe my MSI USB 3.0 adapter? I haven't tired this adapter yet and my one i did use it being used at the moment and can't be turned off.

Thanks

Anybody know if a WinToUSB installation will upgrade to Windows 10? Neither my WinToUSB or a Bootable Clone on USB show the new "Get Windows 10" icon. Only the internal SATA installation shows that. It finally showed up on 2 Windows 7 laptops after the June Patches were applied.

Can I build a Windows 10 USB drive using a 64 bit ISO from a 32 bit PC? I currently have Win 8.1 32 bit installed on a PC with a 64 bit CPU and want to try Windows 10 64 bit from a USB.

Got this error after trying to run the program
failed to run system API.(0x00030015014E0000)

I did a search, but got no results

Hi,

when i start EasyUEFI i get the message "EasyUEFI can only install on UEFI based windows operating system."

My boar is a Asrock Z97 Anniversary and is UEFI-based with Windows 8.1. Why i cannot install EasyUEFI?

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.
