#228842 — UEFI and legacy MBR

hello,
I'm having a bit of bother trying to install windows and Bullseye on PC.
have 2x HDD and 1 SSD
PC bios has option UEFI or legacy menus
Only seemed to work if selected USB from legacy menu to install windows 
from USB stick on only connected HDD.
So then I connect the other drives and install bullseye on SSD from 
bullseye DVD 1, wanting to use other HDD for data.
Installer won't install desktop environment if I just select XFCE but is 
probably another matter.
Grub was complaining about mixing EFI with MBR disk.
I try to start again but if selecting UEFI menu in PC bios PC boots from 
windows installer USB stick but refuses to install on HDD that already 
has windows on it because it has MBR partition table.
How do I erase MBR from disk ?
I've done all this before but forgotten.
I guess boot from something linuxy and erase the partition table of 
offending disk with fdisk?
I'm concerned that there seems to be another layer of control ( MBR or 
EFI ) between OS and PC that's in the BIOS.
