Issues dual booting Kali on new Windows OS’s (Win10, Server 2016,etc) Here is how to tell if your Kali USB stick booted into UEFI or Legacy (BIOS) mode and how to fix it: If it boots in Legacy/BIOS mode, the Kali install will complete but after the install it will only boot Windows and not the new Kali install. If this is the case, you MUST boot the Kali USB installer in UEFI mode. If you installed Windows 10, or Server 2016 or new operating systems first, then the internal hard disk is most likely already using UEFI. Thank you to everyone that contributed to this thread. This thread helped point us in the right direction. As a result, there is not enough unused space available for storing second stages of boot loaders on GPT disks boot loaders are usually implemented so their code stored within the MBR, which cannot hold more than 512 bytes, operates as a first stage that serves primarily to load a more sophisticated second stage, which is, for example, capable of reading and loading an operating system kernel from a file system.We ran into this issue as well.

Such a layout is sometimes referred to as BIOS/GPT boot.Ī BIOS boot partition is needed because GPT uses the disk sectors immediately following the Master Boot Record (MBR) to hold the actual partition table, whereas the traditional MBR-based partitioning scheme does not designate them for any special purpose.

The BIOS boot partition is a partition on a data storage device that GNU GRUB uses on legacy BIOS-based personal computers in order to boot an operating system, when the actual boot device contains a GUID Partition Table (GPT). Do not create a filesystem on it, and do not mount it. Please note that this partition is unrelated to the /boot mountpoint, and will be used by GRUB directly. Note: For GRUB to boot from a GPT-partitioned disk on a BIOS-based system, a BIOS boot partition is required. īecause GRUB does not understand GPT partition tables, you need to create a bios_grub partition then reinstalling Grub, also the os-prober need to be installed to get the others OS detected. First, you need to backup your data, to boot windows you can use Super Grub2 Disk, witch allow you to boot a different OS, legacy or UEFI.
