edit boot disk after changing drive to slave?


Hi

I just added a new hard drive and made it master. I can't boot into RH 9 anymore and I get the kernel panic: no init message. I am wondering if I can edit the boot disk and if so what would the staement be. I was booting off the disk not Grub or Lilo.

Thanks
Lou

geez, you have to make the new hd slave or it will not work.
consider installing boot loader, once you get it up and running again.

Thanks but I needed to put Windows98 and XP back on the new drive and Win98 needs to be C:, etc. Also I wanted to dedicate the old drive to RH9.

Been setting up the bootloaders, twice Grub crapped out on me and left me re-installing and this last time XP glitched. Will try again but I wish there was a way to back up the MBR in case the bootloader dumps again.

To restore the MBR all you need to do is boot the XP install CD to recovery mode and run the fixmbr utility or a Win98 emergency boot floppy and run fdisk /mbr.

By boot disk do you mean a boot floppy? You will need to boot the 1st install cd to rescue mode. This should mount your root partition at /mnt/sysimage. Now:

chroot /mnt/sysimage

Edit the /etc/fstab file and change anything that is label /dev/hdax to the new location of the drive.

mkbootdisk <kernel_version>

You can find kernel version from:
uname -a

See man pages for mkbootdisk for details. If not mkbootdisk then bootdisk.

Thanks for the reply Michael. Tried booting Rescue using the disc but it didn't see any of the partitions. I then went a little further and started to re-install, when it checked for previous installations it said it saw the install but it wasn't initiallized and did I want to continue and lose all data.

I'm going to clean up the disk and re-install.

Thanks
Lou
