[Bug 1937115] Re: Unable to boot/install Impish daily in UEFI boot mode

[sudodus]

I should add, that I installed in a Toshiba,

http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/

and then moved the [internal] SSD to a USB3 to SATA adapter and booted
my Dell Latitude E7240 and it works in UEFI mode. I don't want to
overwrite the internal M2 drive of my Latitude.

Someone else, who has a computer that is affected by this bug may want
to try via mkusb-dus and Lubuntu directly in the affected computer. (But
it seems to me, that the problem is booting the live drive, not
installing and booting after installation.)
