How to fix grub without LiveCD?

[Icon]

Hello, all!
Red Hat Enterprise Linux 4.6 AS can't start. Says:

Booting 'Red Hat Enterprise Linux AS(2.6.9-67.ELsmp)'
root(hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.9-67.ELsmp ro root=/dev/VolGroup00/LogVol00 rhgb quiet
Error 15: File not found
Press any key to continue...

On forums it says to fix it with recovery mode from Red Hat disc, but I haven't any. Tried to start from USB Ubuntu 11.10 but can't found that disc 'cause there is no hd* or sd* in /dev but tons of another devices which whom I know only cdrom
fdisk -l gave nothing
Automatically mounted in media
_boot cdrom
in _boot folders grub and lost+found and files related to 2.6.9-67 so I think they are related to Red hat not ubuntu
but in grub folder files grub.conf and menu.lst are empty so I don't know what and where I must insert to fix grub loader
Hard disk type is special 10k SAS Single Port, so I can't even connect it to another computer to save data and reinstall system (all another computers have only IDE or SATA ports). Anyone help, please?

Why don't you download a CentOS 6.2 DVD?
http://centos.bio.lmu.de/6.2/isos/x8...64-LiveDVD.iso
or
http://centos.bio.lmu.de/6.2/isos/x8...4-bin-DVD1.iso

(If you use a 32bit system, donwload the i386 alternatives instead.)

Thanks for link, will try, I wasn't sure if centos LiveCD compatible with RHEL 4.6

Ah, you use RHEL 4.6. You should probably download a CentOS 4.x CD/DVD then.
