Re[2]: Redhat6.1 crashed

Since you seem to have internet access, try downloading a boot and
root disk from RedHat website..

Good luck.

PS: If RedHat does not have boot and root disk for you to download,
try SuSe (www.suse.com) or try to get to other distro from
www.linux.org...

I greatly appreciate your detail instructions.

My bootdisk doesn't have root directory on it, I think. It automatically went to
/dev/hda10 and mounted root. It passed the clean check for /dev/hda10. It
prompted Remounting root filesystem in read-write mode [OK] too. Then it tried
to do next step and stop there.

I also tried to use "rescue" option when booting from bootdisk. It asked me for
a root disk which I don't have and I am stuck again. Am I dead here? : (

Are you booting the kernel from the bootdisk but using the root as
/dev/hda10?? I am talking about booting using the bootdisk both
kernel and root directory. Do not supply /dev/hda10 as your root
directory to be used, just boot normally as though you have no prior
Linux setup at all. Should boot you using ramdisk (I am not sure, I
have never installed RedHat distro before...)

Then when it boots up, mount your /dev/hda10 to its mount point
(usually /mnt but anything is ok) then go into rc.d and try to clean
up (meaning comment out ANY process or applications that you do not
need to boot up the system - gpm, X, etc...) maybe even getting rid of
modprobe line may help too in case any of your modules are corrupted.
Of course this should be done AFTER you do the file system check in
/dev/hda10..

Then, try to reboot normally to your system. Then, first thing I
would do is to recompile the kernel, to make sure all my modules are
not corrupted, then uncomment 1 application at a time from your init
script. If you can uncomment all the lines without any problem, then
it was corrupted modules, if one of them hangs your system, then you
know which prog is bad, so you can boot with your boot disk again, and
reinstall the package.

Good luck!!!!

The only Redhat bootdisk that I have is the one created when I first time instal
d
Redhat. Is the one you are saying? I tried that one already, it stopped booting
on the same step while booting. How do I mount /dev/hda10? I cannot see any file
un r
the original linux system, how do I clean up my rc.d? What else can I do?
Help........please.
