I made multiboot Lubuntu 19.10 and Windows 10 setup recently (it was Windows-only before).
Then I made Windows the default OS (using
Grub Customizer in Lubuntu).
Now when I use the power button to turn on the machine, GRUB comes on and autoloads Windows, and it runs fine.
However, when I use Wake-On-LAN to turn on, GRUB comes on, counts to 10 but then throws this error:
Failed to boot both default and fallback entries. Press any key to continue...
and goes back to GRUB menu. Selecting
Windows Boot Manager (on /dev/sda1) top entry does nothing, but selecting the second entry
Ubuntu loads Lubuntu 19 fine.
I then rearranged the order via
Grub Customizer to make Ubuntu the default OS again (topmost entry) and booted with WOL, and this time Lubuntu autoloaded normally. So it's only Windows that is not autoloading with WOL and giving error.
I would really appreciate some help as I need the multiboot system to boot into auto loading Windows via Wake-On-LAN, as it always did before I made the system multiboot by adding Lubuntu on it.
Thank you very much.
Additional Info (if helpful):
- Windows is "UEFI", PC's BIOS is set to allow both UEFI and Legacy (I've tried either or both)
Windows Boot Manager (on /dev/sda1)contains the following:
insmod part_gpt insmod fat set root='hd0,gpt1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1 185C-F884 else search --no-floppy --fs-uuid --set=root 185C-F884 fi chainloader /EFI/Microsoft/Boot/bootmgfw.efi
