I recommend that you first disable automatic boot repair from a console in Windows:

    bcdedit /set {current} recoveryenabled No


Try now if that has solved your problem. If not, you may have to manually set rEFInd. I had to do it in my Dell pc following the instruccions in the [rEFInd website][1], in the "Alternative Naming Options / Renaming Files Manually" section. I'll paste here the instructions:

1. Access your ESP, as described in earlier sections.

2. Look for an existing directory called EFI/BOOT or EFI/Microsoft/Boot. If neither of these directories exist, skip the next step. (Note that FAT is case-insensitive, so the name may vary in case.)

3. Rename the existing directory or boot loader file to something else. For EFI/BOOT, try renaming it to EFI/Oldboot. For EFI/Microsoft/Boot, move or rename the bootmgfw.efi file it contains. For instance, you can move it to EFI/Microsoft. This will keep the boot loader accessible to rEFInd's menu, while preventing the firmware from launching it automatically.

4. Rename/move your EFI/refind directory to EFI/BOOT. If you're working from EFI/Microsoft/Boot, you should move the contents of your rEFInd directory to EFI/Microsoft/Boot.

5. Rename EFI/BOOT/refind_x64.efi to the name of the boot loader it's replacing—it should become EFI/BOOT/bootx64.efi or EFI/Microsoft/Boot/bootmgfw.efi.


If that sounds too complicated, and just as a plain-language summary (this may only be valid for some machines. If you don't find some of this directories or files, please read the website instructions):

1. Access to /boot/efi
2. Rename EFI/BOOT to EFI/Oldboot 
3. Move   EFI/Microsoft/Boot/bootmgfw.efi to EFI/Microsoft/bootmgfw.efi
4. Copy   EFI/refind/* to EFI/Microsoft/Boot/*  (* means all content)
5. Rename EFI/Microsoft/Boot/refind_x64.efi to EFI/Microsoft/Boot/bootmgfw.efi
6. Reboot
