(I just had here about 5 paragraphs of text, but all seems worthless, you don't need that much data).
I'm using Kubuntu in BIOS Legacy State as this was the only way I could see USB option in Boot Menu (F12). And it was the only way I could install Kubuntu from USB, from boot. I "burned" USB using OEM Windows 10 and told Kubuntu to take entire disk (effectively wiping out all bloatware).
If I enable BIOS UEFI mode, I see "No Bootable Device" icon because Linux and UEFI don't like one another(?), and already mentioned, list of bootable devices disappear (In Legacy Mode, there are 5 positions, HDD, USB, network etc., in UEFI mode, nothing, empty list).
dd bs=4M if=/path/to/win10.iso of=/dev/sdx && sync
with correct path and correct USB and it didn't work. Screen flickered couple times and the only thing I saw was Kubuntu's logo and it booting up. WinUSB is not a choice since it's seemingly offline, unetBootin never worked. I'm not aware of any such easy tools
I don't know what to do, is it possible to install Windows 10 on Legacy BIOS from USB on Linux?
Any ideas? How can I successfully "burn" USB, boot it and actually install it?
Currently my computer is in Legacy BIOS mode.
Before DD'ing I set USB to
gpt ntfs all formatted. But now it is all:
