Hey, so I installed Kali Linux over Backtrack 5. This booted alongside Ubuntu 11.10 and Windows 8 using GRUB. Now, GRUB boots up and goes into rescue mode, and pretty much whatever I type, it outputs Unknown File System.

I have tried Boot-Repair, and it couldn't install GRUB. I tried again, multiple times (after reboots) and it says Please CLose Package Managers.

I ran the Bootinfoscript, here are my results.
Boot Info Script 0.61 [1 April 2012]


============================= Boot Info Summary: ===============================

=> Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of
the same hard drive for core.img. core.img is at this location and looks
for (,msdos6)/boot/grub on this drive.

My Windows 8 is on SDA3, Kali is suppossed to be on SDA6, Ubuntu on SDA5, and I had set asside SDA8 to try to install GRUB there, after it wouldn't install anywhere else, but it didn't work there, either. I have tried purging and reinstalling, it returns some error about unable to locate dev/sda or something of that nature. I have been trying to solve this probably a total of 8 hours so far, so I seak your assistance, thanks!

You do not have grub anywhere. Most of grub is really inside your Ubuntu install, its boot loader should be in the MBR and it will have core.img in the sectors right after the MBR.

Use Boot-Repair and the option to totally uninstall and reinstall grub2.
