I dual booted my system having windows 10 with Kali Linux. After installing, I rebooted but the grub bootloader doesn't appear.
Then I went to my UEFI setting booting was in 'UEFI first' mode I changed it to 'legacy first'. Now the grub screen started appearing. Kali worked well, but windows 10 is not booting up. I reverted the changes ( legacy to UEFI ) and now only my windows worked.
I have changed the Legacy boot to UEFI mode and disabled secure boot. Still nothing happened. What should I do? I have searched answer but no other question gave satisfaction.

  • Installing kali-linux in Legacy BIOS was unnecessary. Those internet guides mislead people.

You have installed your Kali without UEFI mode, and Windows 10 requires UEFI to boot. You will have to reinstall Kali with UEFI , only then you will be able to dual boot using grub.

Just reinstall using the same partitions with an extra EFI partition. But this time boot your USB in UEFI. Here is a guide to help you install using EFI.

  • so need to uninstall kali first. can suggest a method. i am quite new to it.

  • @Ankit With operating systems, "uninstall" is a concept that frequently doesn't exist (except maybe for some version upgrades). But I'd recommend looking first for a way to install a UEFI-capable bootloader without having to reinstall any of the OSes.
