I have a laptop (IBM T41) with Gentoo Linux installed, with GRUB as the boot loader. I wanted to make this a dual boot system, so I installed WinXP in another partition. I didn't realise winxp would write over the boot partition.
Using fdisk I was able to change the active partition, but if any other partition other than winxp is set active, I get an "error loading operating system" message.
Next I downloaded KNOPPIX (linux on disc), and this boots fine off the cd. I can access the linux partitions and the winxp partition, so, at least none of the information is lost.
I now need to make the original gentoo linux bootable. I presume this means rewriting over the MBR, but I have no idea how. Also, I don't have a linux boot disk...
Can anybody help?
Thanks in advance,
