Hi I have an MSI z270 SLI PLUS MoBo with an i7 Kaby lake CPU, 240GB SSD (with ubuntu installed in SATA1) and 1 TB HDD (with win10 in SATA 2). Currently if I push the power button W10 will boot. I can hold delete to boot into BIOS or F11 to boot into the menu with all the boot options. This displays my external harddrive, ubuntu, bios, win10, (and I believe a win8 install that is no longer relevant).
What I am trying to do is make it so that the default option I see is the GRUB loader (with all the same options) without holding any key. Currently I launch into GRUB after F11 boot menu selection of "Ubuntu". This is so I can select W10, BIOS or Ubuntu there (in GRUB) every time the computer boots without accidentally booting directly into W10 like I am now.
I also wish to maintain the option for delete to launch BIOS on boot in case anything goes wrong. Thanks for your help.
I have tried changing boot order in BIOS, tried editing with e from GRUB, and tried tutorials using the W10 OS and Ubuntu OS all with no luck so far.
Here is a picture of my partition scheme, as I suspect this may be part of the problem. Partition scheme The Ubuntu GRUB loader is a partition on my SSD, but the windows boot launcher is on my 1TB (Accidentally). I suspect getting them both onto the SSD would help my problem. I have deleted the Win8 Boot launcher (which was also on the HDD as I suspected). After finding this thread Why does GRUB load after I select my Ubuntu Partition from Windows Boot Manager? I have tried downloading easy BCD but it gives me the "device in UEFI mode" error and disables many functions. When I boot into SSD it says missing drivers but I can boot into GRUB on the SSD by selecting Ubuntu on the bootlader menu from within BIOS still (after holding F11). Any suggestions or requests for clarification would be extremely appreciated at this point.
