Install Kali Linux on my old HP laptop

Yesterday i wanna try out my new Alfa High-Gain USB Wireless Adapter
And I was like why don’t I also install Kali Linux on my old HP laptop…

I created a Kali Live USB and boot into it.

Problem 1 –> It pops up an error saying CD-ROM couldn’t be mounted
solution: select “Execute a shell” and run the command “mount -t vfat /dev/sdb1 /cdrom”

Problem 2 –> error message: The missing firmware files are: iwlwifi-7260-9.ucode iwlwifi-7260-8.ucode
solution: download firmware (
and copy the firmware-iwlwifi_0.43_all.deb file to Live USB folder “firmware”
cat /proc /dev/sd + tab <-- can use this command to find out sdX

Update Kali Linux

1 nano /etc/apt/sources.list
and add official Kali sources.list Repositories

deb kali-rolling main contrib non-free
# For source package access, uncomment the following line
# deb-src kali-rolling main contrib non-free

deb sana main non-free contrib
# For source package access, uncomment the following line
# deb-src sana main non-free contrib

2 run commands
apt-get clean
apt-get update
apt-get upgrade (install a newer version of tools and removed the older version. It upgrades only tools)
apt-get dist-upgrade (upgrade newer version of Operating System)

——————after all—————-
It works perfectly and i tested my alfa usb wireless card with airmon-ng, airodump-ng, aireplay-ng and reaver to crack WPA, WPA2 also packet injection functions…all works fine …. just it is a slow HDD computer… but It’s fine i still like it for having Linux OS installed on it 🙂
