Boot loader problem

Link to this post 17 Mar 10


I have installed pre Vista windows and Redhat in my PC. Recently I have installed windowsXP for install weblogic server, but after installing XP it is not showing Redhat linux. At booting time it is showing only XP and pre Vista. Can you please help me how get my Redhat back.

Thanks in advance.

This is fairly common, fortunately redhat has it documented in their knowledgebase.

XP just overwrote the MBR on your drive. This is the first 512 byts of the drive where the boot loader lives (or more accurately, today, stage 1 of your boot loader). You should be able to boot from a Linux Live CD and get to a command line and just re-run grub to re-install it into the MBR. I imagine that Windows XP has not adamged the GUID parition table so grub should be able to find the rest of the data it needs from there.
