I have 32GB 10 class MicroSD card, a microSD-USB adapter, an UEFI-based laptop with built-in microSD reader, USB 2.0, USB 3.0 (at least blue) ports and I want to boot the laptop with Windows 7 from the SD card. Laptop does not have legacy boot option. Secure boot is disabled. Fast boot enabled; Disabling fast boot makes laptop screen being black without booting (I somehow managed to go back to fast boot).
I want to boot Windows 7 from sd card as UEFI. I have tried to write x64 Windows 7 image as “Windows To Go” to the SD card via Rufus 3.2 (for others I also used Hasleo WinToUSB). In the configurations I specified GPT, NTFS, 4096 basic cluster size. Imaging was successful
After attaching SD card to USB 3.0 (same for 2.0 and internal sd card slot) the Windows Boot Manager screen appears with error “An error occurred while attempting to read the boot configuration data” File: “EFIMicrosoftBootBCD”, Status: 0xc000000d.
That file (and the whole path, i.e. folders) indeed does not exists, at least when I see sd card through explorer. Disk Manager shows two partitions for sd card: the first one is 260 mb and I can’t see its contents.
Perhaps put bootloader manually to the viewable partition? But I can’t find where I can get it in the Internet.
