- - GRUB 15 Error? (https://www.linuxquestions.org/questions/linux-newbie-8/grub-15-error-705769/)

I installed a new RHEL 4 AS Update 6 OS and this gave me the error:

Code:

Attempting Boot from Hard Drive (C:)

GRUB Loading stage1.5.



GRUB Loading,please wait

Error 15

Error 15 is "file not found", so you most likely have a problem in your menu.lst/grub.conf

How to solve the issue?
Will Rescue Disk Solve the issue?
Do I need to install OS from scratch?
Just for your info, I had configured RAID 0+1 from BIOS.
Installed LVM..So I guess the incorrect LVM Partitioning may be the culprit.

You could start by posting menu.lst

How can I reach to that file?
Do I need to boot through rescue disk?

If you have one, that would work - then make sure you mount your boot partition.

I went into rescue mode.
Mounted to chroot /mnt/sysconfig
Now I am in #ssh shell.
I checked with /boot/grub/grub.conf and found an entry saying:
#boot /dev/sda

Sorry I forgot to tell you something.. I had already 2 SAN Switch with name /dev/sda, /dev/sdb and /dev/sdc.I installed a new OS on /dev/ccissd0p0 local partition.
While Installation I choose /dev/ccissd0p0 partition and formatted it leaving the rest connected to MSA.

What I think is #boot /dev/sda may be clashing with /dev/sda of MSA?
Correct me if I am wrong

I Tried booting through rescue disk :

#mv /dev/sda /dev/sda.old

Removed the hash in fron of #boot /dev/sda in /boot/grub/grub.conf file
And Then rebooted the system.
But No improvement/clue to what is going wrong.

Do I need to run #grub-install /dev/sda

Billymayday,
I need your help and am sure you gonna help me in this regard.

I looked into another machine which is running without any issue and is also connected to MSA.
The Entry for running machine includes:

Code:

#boot=/dev/sda

default=1

timeout=5

#splashimage=(hd0,0)/boot/grub/splash.xpm.gz

hiddenmenu

My Machine Entry was also same except on my machine it says:

Code:

#splashimage=(hd4,0)/boot/grub/splash.xpm.gz

Why is # being put to machines connected to MSA?

The # simply comments out the line, and the splashimage just puts a graphic behind the menu. Can't do a lot unless you can post the menu.lst from the version that doesn't work.

Can you also post "fdisk -l"
