/dev/sda– Secondary internal disk (despite the
/dev/sda1– Old ESP, not actually used.
/dev/sda2– An unused Linux, for backup purposes.
/dev/sda3– Swap partition.
/dev/sda4– Windows 10 installer (NTFS formatted, copied from an ISO, due to a lack of a spare USB that could fit it).
/dev/sdb– Primary internal disk (despite the
/dev/sdb1– The actual ESP in use, with rEFInd on it.
/dev/sdb2– Debian. My home ❤.
/dev/sdb3– A cleanly formatted NTFS partition, prepared just for Windows.
/dev/sdb4– Shared FAT32 partition for data storage.
I want to install Windows 10 onto
/dev/sdb3, so I made a temporary partition on
/dev/sda4 to hold the Windows installer files, because I lack a sufficiently large USB to act as an installer disk. Once that was done, I booted into the installer via rEFInd, and began installation. However, I could not get past the beginning of the phase where it begins to copy files. It complains that the EFI partition (the ESP) is incorrectly formatted as NTFS, even though it is clearly FAT32. The target partition for Windows itself is NTFS, as is the installer disk.
Is Windows supposed to be this hard to install? 😣
