Hi All,
So my laptop upgraded to the latest version of Windows 10 recently, and this seems to have undone the hack of replacing the default bootx64.efi file. That is, the file is still SystemD’s boot loader, but somehow I’m back to only being able to boot Windows reliably. Has anyone else seen this particular frustration with an upgrade? I note that my laptop came with Windows 10, so this was just an incremental update as far as I now.
Thanks for any ideas. This is kind of maddening. Best, Zack.
Hi, I haven't updated Windows 10 in quite a while so I haven't experienced this, but have you checked to see if both the locations to which you copied the systemd-bootx64.efi are still OK? On my (HP) laptop, I have systemd's boot loader copied to both $ESP$/EFI/Boot/BOOTX64.efi and $ESP$/EFI/Microsoft/Boot/bootmgr.efi. Windows 10 does make changes to critical files through regular updates, but these are the only two files that should mess with the boot process. A more awkward (but more stable) hack would be to create an ESP on a USB stick and install rEFInd or grub to that partition. Systemd-boot can only load applications located on the partition it is currently on, but rEFInd and grub both support booting across devices (in principle). My laptop's BIOS Setup allows me to prioritise USB sticks over internal hard drives at boot time so this should be a reliable way to multi-boot, though I haven't had the time to test it. -- Murari
