efibootmgr may need to be corrected. Windows probably deleted your Qubes boot entry. There are quite a few EFI related posts in the forum that should cover how to check and update.
Edit to add Docs page:
Successfully installed in legacy mode, but had to change some kernel parameters If you’ve installed successfully in legacy mode but had to change some kernel parameters for it to work, you should try installing in UEFI mode with the same parameters....
Edit to add another forum post:
If your device is /dev/sda and efi partition is 1 then :
efibootmgr -v -c -u -L MichaelA -l /EFI/qubes/grubx64.efi -d /dev/sda -p 1
If you use qubes os as external device, folow this (I assume that your device is /dev/sda and efi partition is 1) :
cp /boot/efi/EFI/qubes/* /boot/efi/EFI/BOOT
mv /boot/efi/EFI/BOOT/grubx64.efi /boot/efi/EFI/BOOT/bootx64.efi
mv /boot/efi/EFI/BOOT/grub.cfg /boot/efi/EFI/BOOT/boox64.cfg
efibootmgr -v -c -u -L MichaelB -l /EFI/BOOT/bootx.64efi -d /dev/sda -p 1
