Re: 'error: invalid signature' when booting Windows 10

[David Collier]

when I try booting from the usb stick it indeed shows two boot options,
'Patriot Memory PMAP' and 'UEFI: Patriot  Memory PMAP' but when I try
picking the UEFI option it fails with message

error: file '/boot' not found

however, if I boot from this stick in non UEFI mode I see that it has two
partitions, and both of them have /boot directory.

Any idea what could be wrong? Some search suggests that it could be due to
the fact that I copied the .iso image to the stick using dd, is this the
case?

thank you,
