Hello,\nI own an Asus M5A97 R2.0 mainboard with Bios version 2603.\nI have installed Windows 10 in legacy mode. Additionally I own a SSD on which I often test different Linux distributions. These are usually installed in UEFI mode\nMy problem: these operating systems (installed in UEFI mode), are stored in the boot menu of the computer (F8 key when starting the computer) Therefore I see several old operating systems in the boot menu which are no longer present. Is there a way to clean up the boot menu ? \n\nWindows-Tools like "EasyUEFI" unfortunately do not work because Windows was installed in legacy mode. The Linux tool "Efibootmgr" recognizes the superfluous entries and removes them apparently, but after a reboot they are available again.
