Well, I've done it again! I am running a home built machine with 3 hard drives in it. I have been going into the bios to switch between drives (had a copy of PCLOS2009 on one, XP on another, and on the third PCLOS2011.6) I typically operate from the third drive as the 1st drive to boot from.  A little while ago I decided to look at the alot version of Narly Nachos and installed it beside the drive with PCLOS2009.2 (had that drive as lead in the bios). The problem arose when I rebooted the machine and lo an behold the Narly Nachos boot loader was not on the drive with PCLOS2009.2 but rather it had overwritten (you guessed it) my grub on PCLOS2010.6. Now I had an entry for all drives in the machine but neither PCLOS version would boot. Finally the question! If I unplug the drives with 2009.2 and XP on them (I should have done this prior to installing Narly Nachos) is there a way to replace the grub on my 2010.6 install?  I don't care if Narly Nachos works just get back my primary operating system.

You could always boot from a PCLinuxOS livecd and redo MBR from there.

When you say redo MBR I think of Windows...there is no windows partion on this drive only 2010.6. I want to replace the grub.

Sorry Mac, I followed your recommendation and got my PCLOS2010.6 drive back! I guess MBR is MBR even when it's grub.

Well quit thinking of Windows and think of PCLinuxOS, where Redo MBR will be found at PC --> More Applications --> Configuration --> Redo MBR. You can run it from your PCLinuxOS liveCD, and if done with all drives attached, will put stanzas to boot all of your installed OS into your menu.lst.

This MBR is one great tool, as it saved me just recently from a blinking cursor. Thank you to the developers of PCLOS.
