USB-boot fail: Windows To Go Creator in Partition Assistant Pro 7.5.1 EFI dir/partition missing.
Hi, I tried making a "Windows To Go" on a SanDisk Ultra Flair 32GB. Since my Installed Windows with programs is much greater than 32GB, I choose iso source, downloaded Windows10_InsiderPreview_Client_x64_en-us_18272.iso, and fed that to the creator. The Wizard completed successfully, but the pen-drive refused to boot. Upon inspection I could see that the pen-drive had neither a EFI partition or a EFI directory.
