Ultracopier for linux debian not showing up windows#Now it should be easier to get the Debian installer to boot in UEFI mode, just like your existing Windows installation does. ![]() If you find a "BIOS" setting that allows to force the system to UEFI only, select that setting or there is a setting that mentions CSM ("Compatibility Support Module"), disable it. That may make installing a dual-boot configuration easier.Īs the second step, you probably should disable the legacy BIOS compatibility feature, if you can. So, as the first step, see if Lenovo has a an updated firmware ("a BIOS update") available for your model, and install it if there is one. There are lots of other similar bugs out there, suggesting that many system vendors have done very little testing beyond "does it work with Windows?"įortunately, the system vendors occasionally get firmware bugs fixed. Others will accept those requests, but will refuse to use them unless they describe themselves as "Windows" or similar. Some systems simply ignore valid requests to add new boot entries. Despite the specification for boot entries and boot order being quite clear about how things should work, there are lots of systems in the wild which get it wrong. Many UEFI firmware implementations are unfortunately buggy, as mentioned earlier. There is also the problem that some UEFI firmware implementations are buggy and/or Windows-centric. If you did not opt to create one on your HDD, there was no valid place to install the UEFI bootloader. When in BIOS mode, the installer also won't tell you that installing an UEFI bootloader requires having an ESP (EFI System Partition) on the disk you want to install the UEFI bootloader onto. So it might have booted the Debian installer in BIOS mode, and thus been unable to complete the installation of an UEFI bootloader in the standard way. It looks like your laptop may currently prefer booting in legacy BIOS mode over UEFI, if the boot media has both options available, and the Debian 10 installation media does indeed have both options. that "Windows Boot Manager" text in the BIOS settings) - and that is a requirement to complete the installation of an UEFI bootloader. An OS installer running in UEFI mode could technically install a BIOS-based bootloader instead of UEFI-based one, but the opposite is generally not possible as activating the legacy BIOS compatibility requires disabling the UEFI Runtime Services interface, which is needed to write the boot settings into system NVRAM (e.g. ![]() UEFI) you use to boot the OS installer will automatically determine which mode the new OS to be installed will use. ![]() If your BIOS has a boot option that says literally "Windows Boot Manager", that is a pretty strong indication that your Windows has been installed in UEFI style.The fact that the Debian installer even offers to write GRUB to the MBR indicates the Debian installer has been booted in legacy BIOS style.Ī 16-bit legacy BIOS bootloader cannot chainload an UEFI bootloader (without first transitioning into either 32- or 64-bit mode and setting up an UEFI environment, which kind of defeats the purpose of being in the legacy 16-bit mode in the first place). Ultracopier for linux debian not showing up how to#I would like to boot automatically on Windows unless I keep SHIFT pressed to boot on Debian (I know how to do that as soon as GRUB is showing at startup. I do not have any option in my BIOS to trust/choose an EFI file, as is often pointed to in the forums I have checked. I have disabled secure boot in my BIOS, but even so the computer boots automatically on Windows without showing GRUB, and Windows boot manager is the only one detected by my BIOS in the boot manager. I refused, and asked to install GRUB onto the hard drive on which Debian has just been installed (which is different from the SSD on which Windows is installed). Oddly enough, the installer told me that it did not detect Windows and asked me to confirm to write GRUB to the MBR. Ultracopier for linux debian not showing up windows 10#I have one SSD on which Windows 10 is installed, and one hard drive initially partitioned entirely in NTFS - but I shrunk the NTFS using the Debian installer and installed Debian on the newly freed space. ![]()
