No manufacturing splash screen so no BIOS access

Hey,
I recently installed xfce (debian 9) and I dual booted it with windows 10.
When I press startup button a black screen appears and I directly get 'booted' into grub bootloader. I tried removing my linux partition so that grub would be deleted but there is no way to do this beceause I can not access my windows os. This is beceause I changed boot mode from urri or something like that to crm. To change this back I need to get into the BIOS. I have tried rewriting my linux partition by installing fedora over it but I can't manage to get boot from usb working in grub, it tells me hd1 C/H/D values not found.
P.S. Sorry if I sound stupid, my English is bad and I do not have a lot of experience using linux or grub.

I believe you mean UEFI boot, but it would help to know what kind of system you have. The BIOS splash happens well before any OS or bootloader is run, and while the delay may be short, you can typically hold down whatever key (ESC and F1 are good guesses, but it could be something else), it'll pop you into the BIOS, where you can adjust such things.

GRUB is the bootloader; it's what prompts you for Linux or Windows, and it may (depending on installation), live on its own partition, so deleting the Linux partition would just make that particular choice in GRUB non-functional. You can probably look up the BIOS key on the Internet, or post it here, and someone may know.

Find the manual for your computer on-line, and find out how to enter the BIOS. It has not to do anything with Linux or your software installation. Google for "XXX YYY enter BIOS at startup" where XXX and YYY are your computer name and model.

it has nothing ot do with Linux if you cannot get into the BIOS.
please do as the previous poster said.

fwiw, my monitor takes a few seconds to come on, and that is usually the time when the BIOS offers to press a key combo to enter it, so i usually have to do it blindly.
what i do is i boot the computer and press the key (Del in my case) repeatedly about twice per second until i see the "Entering setup..." message.

We did have a recent thread that was similar. The OP removed hard drive and was able to access bios.
