I installed Kali in virtualbox with Debian as my host. I've done it several times. But, when I reboot my host I noticed Debian is missing from the list of OS'es in the GRUB menu. It's showing Kali. The only OS on this machine is Debain.When I click it, it boots Debian. It's odd because I have never installed Kali on my main drive, only in Virtualbox.I checked the GRUB config file, and I noticed this:lsb_release -i -s 2> /dev/null || echo DebianWhen I run that on Debian the output isroot@Sophie:/home/sophie# lsb_release -i -sKaliHow and why did virtualbox do this and how do I fix it?cat /etc/os-releasePRETTY_NAME=Kali GNU/Linux 1.1.0 (moto)NAME=Kali GNU/LinuxID=kaliVERSION=1.1.0 (moto)VERSION_ID=1.1.0ID_LIKE=debianANSI_COLOR=1;31HOME_URL=http://www.kali.org/SUPPORT_URL=http://forums.kali.org/BUG_REPORT_URL=http://bugs.kali.org/Edit:Some day sago I did add the Kali repositories to install something, then I removed it. Could that have done it?
Adding Kali repositories has changed the output of lsb_release on Debian host

Adding the Kali repositories would indeed change the /etc/os-release file. The version in Kali's repos is probably newer than the one in Debian's so apt downloaded it and replaced the one on your system. If you're very, very lucky, that's all that broke. Do not, I repeat not, ever mix repositories from different Linux distributions.
