Public bug reported:
Original: Fujitsu LIFEBOOK E782 with Windows 10 Pro; one SDD, no further
HDD
First installation of Ubuntu 18.04 LTS one week ago alongside Win 10 worked
fine.
Booting the Desktop-CD from USB (with no needed UEFI setting changes) worked
fine, partitioning with gparted and installation on Desktop-CD finished
normally.
During booting always GRUB screen to choose between Ubuntu and Windows. -->
Perfect.
BUT After first use of Windows 10: No GRUB menu anymore, but always direct
start into Windows.
Reason!?: Fast boot was not deactivated. Deactivation did not solve the
problem. (And in UEFI menu no secure boot options available that could be
deactivated. And if these would be the reason, Ubuntu should not have worked
before!?)
When entering boot options on startup and choosing Ubuntu (which is
still at first boot position) nothing happens. Obviously second boot
option "Windows" is always entered because first boot option "Ubuntu"
fails.
BUT why is a priorly fully-working Ubuntu not usable anymore after one
Windows start with first activated but meanwhile deactivated fast boot
option?
My try: New install of Ubuntu in the same way like initially done - with the
Ubuntu-Desktop from USB.
BUT NOW: During installation GRUB cannot be installed anymore - tried two times
now.
During installation I left the boot loader installation location to default
/dev/sda, although precisely the Windows bootloader is at /dev/sda2 because I
read multiply times that in EFI mode this is detected automatically.
Detailed system info will hopefully be in the automatic debug information with
the report.
Thanks for any help,
best regards!
