It is a Laptop Asus, I was installing Kali linux from a USB stick. Before in the laptop I had Windows and Linux Mint.welcome to the forum filippo_1980,
its going to help if you can elaborate.
laptop, Desktop PC / what was on it hard disk before install? What was install media usb stick or cd/dvd Do you have a liveOS on a usb stick ?
Power is on for PC ?
you should be able to still boot from usb with any luck, but do yo uhave or can get a live OS onto a usb stick. If so you shutdown and stright after power hit f9 or equivalent to get a choice of boot options .
how can I give you more information?...I tried to put linux mint on a usb stick but nothing...laptop is not reading the usb.Obtain a bootable USB of a 'Live' Linux distro - NOT Kali !
Boot the machine from the Live USB. It should boot even if there is no operating system on the internal hard drive. Install Linux from there.
If it does not boot you may have other issues such as catastrophic hardware failure or a BIOS mis-configuration.
More information is required.
only iso...may I ask you where I can learn more about this live option? I am not getting what you meanok so theres a good chance Windows might still be there, you were basically going to replace Mint with Kali ? Did that kali on usb have live option or was it an install iso only?
