Lost root passwd and can't enter resuce mode

Hi,

I'm running Mandrake 10.1 as a web/fileserver. By misstake I lost my root password. Since that has happened before there was no course to panic, instead I tried to boot from my install CD and then entered rescue mode.

But when entering rescue mode I get the following error:

hda: 43403252 sectors (2222MB) w/4112KiB Cache: CHS: 2136/127/16
hda: INVALID GEOMETRY: 127 PHYSICAL HEADS?
ide-default: hda: Failed to register the driver with ide.c
Kernel panic: ide: Default attach failed

However, I can boot my system and log in as any user, but I can't do anything with the system since I don't have root priviledges.

Does anyone know a way to fix this corrupt file system?

I kind of doubt it's all that corrupt if users can login ok.
Login to level 1 ( one ) by appending init 1 to the end of the boot loader.
This will allow you to changed the root passwd without knowing it first.
For example:

Code:

title Fedora Core
	root (hd1,1)
	kernel /boot/vmlinuz-2.6.12-1.1447_FC4 ro root=LABEL=/ rhgb quiet init 1
	initrd /boot/initrd-2.6.12-1.1447_FC4.img

Thank's a lot. I'm using Mandrake, is it just to exchange FC to mdk?

You will need to work with the operating system that you have. Also, my example was using the GRUB and you may be using LILO boot loader.
