I'm pulling my hair out. I try to exhaust my research before asking questions, and I'm at that point.

I've got a Panasonic Toughbook, while older (32bit) it exceeds the system requirements. I'm doing a hard disk install, no dual boot.

The first error during install was during the network mirror. It crashed and I was forced to disable the network card. Research shows that many say its due to network connectivity issues, but what I find interesting is I have zero internet issues when booting from Kali Live.

So I skipped this part. I'll deal with it later. The next step of installation returned this error: "grub-pc package failed to install into /target/". So I read, and read. I found out that I could install GRUB later using the Live USB, so I had to skip this part.

So after install, I restarted the computer. Booted Kali LIVE.

Terminal--> Ran the script below, and of course, I get an error: "grub command not found"

Code:
mount /dev/sda1 /mntmount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt
grub-install /dev/sda
update-grub
exit
umount /mnt/dev/pts
umount /mnt/dev
umount /mnt/proc
umount /mnt/sys umount /mnt

I'm out of ideas. fdisk shows 3 partions. SDA1, SDA3, SD5. KALI is on SDA1.


Can anyone please, please assist.

Many thanks,
Rob
