Originally running dual boot windows and Ubuntu through grub. PC now boots into Windows after performing a boot repair.
Is it possible to reset grub as the bootloader using Windows cmd?
I'm stuck doing it this way as Windows BSOD on startup.
Already tried using
Bcdedit /set {bootmgr} path /EFI..... Etc
This does not affect startup
I have noticed {bootmgr} device is partition=c: which looks problematic but receive an error when trying to change to partition = /dev/sda1 or similar.
I am unable to look at (mount) the Ubuntu partitions from a windows environment so I can't check the files even exist at that path.

What was the full path you tried setting for bcdedit? Should be
– lx07 – 2019-06-12T09:58:47.770bcdedit /set '{bootmgr}' path \EFI\ubuntu\grubx64.efiorshimx64.efiif you have secure boot. Note the direction of the slashes: '' not '/'. See http://www.newfreesoft.com/linux/windows_and_ubuntu_dual_system_repair_of_two_ways_uefi_boot_1552/Yes, the full path was as you have written. Now I tried with shimx64.efi still no result. Slashes was my fault, typing on phone. Thanks for the reference. – Droobasaur – 2019-06-14T10:56:35.817
download linux repair disk, create a live usb and boot on to it. it will run a scan and fix boot issues, most of them . you can download it from sourceforge official website. – Siyavash vaez afshar – 2019-06-19T15:04:53.330
I'm asking for a way to do it without access to another computer. I thought there must be commands in bios that help you change the boot settings. But as far as I can see, the only option is to choose between physical drives. – Droobasaur – 2019-06-22T02:19:10.590
