"Windows 10 Pro Build 9926 (x64-LiveUSB-DesktopToGo + Setup) This is a fully portable and functional Windows 10 Pro 64bit Desktop that can be run from any 32GB or larger USB 3.0 Removeable Flash Drive or HDD. This Portable Windows Pro OS is setup to Boot and Run in MBR Legacy Mode only from USB Flash or HDD! Boot from any PC that's supports 10 64bit to have your personal Desktop on the Go. WARNING: After you extract ISO files to USB the Windows10.vhd file that the LiveUSB-DesktopToGo resides in may be set to readonly! You must uncheck readonly by (right/clicking) on file and unchecking readonly box before it can boot and expand for the OS to properly work. Windows Setup is included to install x64 Pro on any PC It will install in MBR Legacy Mode and 64bit UEFI Mode To install in UEFI Mode you must follow the UEFI Setup Guide. You can install your favorite programs to run and have your Documents, Music, Videos and Pictures where ever you go. The faster the drive the better experience you will have. It is highly recommended to use a USB 3.0 flash drive or HDD. Using a USB 2.0 drive will run to slow for a good experience. I have found it boots and runs smooth from a USB 3.0 external HDD from a USB 2.0 port. Booting from USB 3.0 port sometimes takes a couple of tries from flash drive, so if you cannot boot from 3.0 port try a 2.0 port instead. Please remember this is a Windows 10 Pro Technical Preview Build 9926 OS and is still in beta and will have bugs and gliches fixed as MS releases them. A 32GB Drive or larger must be used for the LiveUSB Edition to boot! The Windows Setup can be run from iso, but the LiveUSB will not and must be run from USB Flash or HDD to boot and work. Instructions on how to create Bootable Windows Desktop: Plug in your USB Flash drive if you have not already done so. Start a Command Prompt as an administrator (click the Start button and type CMD, right-click on cmd.exe and select “Run as administrator" and accept the UAC prompt, assuming you are using Windows Vista or Windows 7) For Windows 8,8.1 (right/click) on StartButton and choose Command Prompt (Admin) Type diskpart and then press ENTER For each line, type the parts on BOLD and press ENTER after each entry, the notes are for reference only DISKPART> list disk (note: this will list the disks on your system. Typically look for the one that matches the capacity of your USB flash drive) DISKPART> select disk x (note: x is the number for your USB flash drive you obtained from the list command above) DISKPART> clean (note: this will erase your USB flash drive) DISKPART> create partition primary (note: this will create a new primary partition on the USB Flash drive) DISKPART> select partition 1 (note: this will select the partition you just created) DISKPART> active (note: this will set the new partition as active, which identifies it as a valid system partition) DISKPART> format FS=NTFS QUICK (note: this will perform a quick format on the USB Flash drive) DISKPART> assign letter=y (note: where y is the drive letter you want to choose for USB Flash drive) DISKPART> exit Now use command below to transfer MBR BootSector to USB Flash drive. bootsect /nt60 y: (note: where y: is the drive letter assigned to your USB Flash drive – this will copy across the boot files) Now the last thing to do is navigate to Win10.PRO.9926.x64.LIVEUSB.iso in explorer and (right/click) on file and mount iso or extract to the root Dir of newly created USB Flash drive. WARNING: After you extract ISO files to USB the Windows10.vhd file that the LiveUSB-DesktopToGo resides in may be set to readonly! You must uncheck readonly by (right/clicking) on file and unchecking readonly box before it can boot and expand for the OS to properly work. Thanks BigReds"
