Manual procedure using Windows 8 Tools to make USB-harddisk bootable on UEFI computer: Boot and EFI folder are created on FAT32 partition. Install of Win 8 on USB using UEFI computer and latest beta version of WinNTSetup is OKĭid not use any other tool. GPT partitioning is not needed and unwanted because it would only boot on UEFI firmware. The first Boot partition E: is FAT32 Win8 Format and contains only the EFI folderĪnd the second partition M: is NTFS and filled by using WinNTSetup. On computer with UEFI firmware I can Install Windows 8 on normal USB-harddisk having MBR and three primary partitions. The boot CD's were not compatible with UEFI. UEFI does not like Grub4dos and so all boot Images failed. On trying to boot with my existing USB-harddisk Or CD / DVD then initially Everything Failed. Windows 8 came on computer with UEFI firmware and GPT partitioning of the internal harddisk. UEFI Windows 8 + BIOS Grub4dos = MultiBoot USB-Harddisk
