Computer is unable to boot after installing Kali

Question

Previous situation was a working dual boot Ubuntu/Windows 10.

I decided to install Kali Linux instead of Ubuntu, so during the installation process, I removed and overwrote both ext4 partitions that contained Ubuntu.

During the installation, Kali told me it was unable to install grub.

Rebooting results in a grub prompt. I am only able to get into Windows by pressing F12 when the Dell logo is visible on screen.

I've tried to fix it by running the boot-repair-disk from here. This doesn't work, but provides a boot info summary, which can be found here.

Does anyone know how to fix grubso that I can boot into Windows and Kali?

Update I'm currently booted into Kali by using SuperGRUB2 Disk. When I tried to run grub-install, I got bash: grub-install: command not found.

I fixed that by removing and reinstalling grub. After that:

#sudo fdisk -lu

Solution 1

The problem was that I had not installed Kali as EFI. After I recreated the USB drive (using Rufus), the reinstall went smoothly.

Solution 2

From your terminal, run the following commands:

$ sudo add-apt-repository ppa:yannubuntu/boot-repair  

$ sudo apt-get update

$ sudo apt-get install boot-repair

$ boot-repair

I hope this help fix your GRUB issue

Please be aware that Kali isn't really intended for daily use (it simply isn't. It's possible to make it work by creating a non-root user and stuff, but again, the OS isn't intended for this). I'd advise installing it to a flash drive and booting as necessary, and using a proper OS meanwhile (Ubuntu, Arch, Windows etc). If you really want to use pentesting tools in your daily OS, I'd look at something like ArchStrike.

Thanks for the advice. I use Windows as my daily OS, and found that installing Kali makes it work faster than from my USB.

Okay, so everything now works fine right?
