RHEL4 Upt(2): Operating System Not Found ?

Muhammad Ahmad — Thu, 10 May 2007 09:11:41 GMT

Hi,

My HP-Proliant "ML570" Machine faced an abnormal shutdown due to a power failure.

After the event : "Operating System not found" appeared @ system boot-up time & the system was unable to load operating system.

O/S: RHEL AS 4 update 2
Software Raid 1+0 were configured.

Facts Gathered:

All mount points are accessible through Linux Rescue Environment.

Try to re-install the grub, it failed with error "not a charactor device" { i have tried by giving all the available paths )

try to use fdisk, it failed with "Not a valid Partition table"

Any suggestions / recommendations will be highly appreciated.

Regards,

Shalom,

Its a known bug.

It was fixed in RH 4 update 4 for certain.

Here is the fix after install trick.

1. boot redhat cd 1
2. enter "linux rescue" at isolinux prompt
3. no networking, mount drives
4. at shell prompt, type "grub"
5. find /grub/stage1
6. root (hd0,0)
7. setup (hd0)
8. root (hd1,0)
9. root (hd1)
10. klingon deathgrip
