Hi,
I had a dualboot with windows 10 and deepin and i deleted the windows partition, but the windows boot manager is still available in the bios. Is there a way to delete the windows boot manager?

Thanks!

UEFI boot entries are stored in NVRAM of your motherboard. Thus you need to use UEFI boot management utility such as efibootmgr or refind to delete redundant boot entries.

Hi thx for the reply.
I already tried it out with efibootmgr and did sudo update-grub2. The boot manager doesnt show up anymore in the session, but if i reboot the device, it will still show up in the bios

The grub2 can also boot the Windows boot mgr.So it's not a bad idea to install grub2 if you need to boot both Windows and deepin.
