As suggested I typed efibootmgr -v and everything seems to be fine. I get
BootCurrent: 0001
Timeout: 1 seconds
BootOrder 0000,0001
Boot0000* debian Vendor(99e27e7-75a0-4b37-a2e6-c5385e6c00cb,)
Boot0001* UEFI: SanDisk Cruzer Blade 1.27
HD(1,f8c,340,1876769c)File(EFI\boot\bootx64.efi)..B0
How do I tell UEFI the parameters or how to boot?
If I do not manage to install Debian with UEFI, I will switch to the
legacy BIOS option. Is there any adavantage using UEFI?
Thanks,
Daniel
