Going on hour 9 of installation. Grub problems

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

You can always take the hard drive, put it in another system and do the installation there and finally put it back.

Without any details on the crash and/or logs, there isn't much we can do. You don't even say where the installation crash.
