Comment 10 for bug 1845289

Hi @cyphermox, I have tested with F12 on my Alienware Alpha:
* F12
* Select Windows Boot Manager
* Goes straight to grub

So no difference regardless of which boot option I select.

How was the installation done?
I installed Ubuntu 19.04 the upgraded to 19.10.

Here's my disk layout:
~> sudo parted /dev/sda print
Model: ATA Samsung SSD 860 (scsi)
Disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number Start End Size File system Name Flags
 1 1049kB 512MB 511MB fat32 boot, esp
 2 512MB 513GB 512GB ext4
 3 513GB 513GB 16.8MB Microsoft reserved partition msftres
 4 513GB 1000GB 488GB ntfs Basic data partition msftdata

Could you please describe how the disk was partitioned for dual-booting, and the steps taked in the installer?
I can't remember exactly what I did, as it was quite a while ago. However, the basic steps were:
* Install Ubuntu using 512GB
* Install Win10 into the remaining space
* Boot the Ubuntu usb and chroot into the installed ubuntu and re-install grub there.

Is there any extra info you want me to collect about my PC?
