I have been a rather big idiot. I had a very secure linux operating system called "Kali" that I should not have been using since I did not have enough knowledge about Linux, bash shell etc. Because of that I decided to get rid of it. Unfortunately, the OS refuses to boot into anything but itself. Even upon instructing the bios to boot into my USB, Kali Linux boots instead.
I decided to wipe my hard drive, since that surely should delete Kali, and allow me to boot from my USB and install a different OS instead. Since I have a lack of experience with the bash shell, I had to look up a tutorial about it. This landed me on this tutorial: https://www.howtoforge.com/how-to-securely-destroy-wipe-data-on-hard-drives-with-shred. O decided to wipe the whole drive, since I had no important files on it. This was likely my mistake.
I followed the tutorial, and it seemed to somewhat work. I run the command through Kali, expecting it to shutdown or something alike once its finished. It didn't, but I did see some noticeable changes. Some icons were gone, folders looked like text files. I proceeded to restart my PC.
Upon booting up, I receive the error: PXE-E61: Media test failure, check cable. Followed by: PXE-M0F: Exiting PXE rom. I heavily doubt any cables came loose, it's definitely the shred command that did it. One key recovery button does not allow me to reinstall windows and return to factory settings, since I wiped the whole drive thanks to my stupidity.
Booting from a USB containing he installation for Debian does nothing, as all I receive is "No bootable device -- insert boot disk and press any key" along with the same errors as before. I tried every USB port.
I set my Sata HDD to be the first to boot, followed by Sata ODD, then Network Boot and then USB HDD.
Upon making USB the first to boot, nothing changes. I get the exact same error messages
I realise I've done something incredibly stupid, it's all my fault, and it probably deserve it. But is there any way to fix my Hard drive, and install the OS on my USB?
Thanks in advance.
