I updated from ubuntu 19.04 to 19.10 yesterday and Windows 10 won't boot anymore from Grub menu. It worked fine before.

For now I can boot to windows by changing the priorities in the bios to windows bootloader but I prefer to have a better solution. I went through the solutions proposed in this post: *Grub* Windows 10 doesn't start anymore but none of them worked for me.

Fast boot and secure boost are disabled in the bios. Did anyone have the same problem after updating ?

  • Yes, I have the same problem.

First you need to install and run boot-repair:

Then check the boot-repair report. If the bottom of the report tells you:

For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

Boot into Windows by changing the BIOS boot order. See the section in link below on Access BIOS/UEFI:

After successfully booting into windows via BIOS/UEFI boot order override, open a command prompt as administer and run the bcedit command above.

Then reboot back into BIOS/UEFI and reset Ubuntu to top of boot order.

Also note boot-repair can create about 7 custom entries to boot Windows and Ubuntu from UEFI. In my experience they won't all work. After you fix the booting issues see this answer:
