RHEL4 U5 Install, Boots Up with “GRUB” error on screen. 29 October 2008

Posted by Maulvi Bakar in : Linux,Work , 1 comment so far

This one is a funny error. After finishing the installation, the system reboots and ‘poof’ on screen only displays “GRUB”.

My suspicion is that, GRUB somehow or rather did not install properly onto MBR. Considering previously that the system comes only with a single harddisk. Later on, after fixing a second harddisk, the OS was re-installed with RAID1. Maybe that’s the cause as the old GRUB was not properly overwritten.

Basically, I re-insert the installation CD and boot up into rescue mode.
linux rescue

Upon boot up, mount the filesystem thus –
# chroot /mnt/sysimage

Use grub the regenerate the grub stuff on both hdds thus –
# grub

On the grub command line, select the 1st harddisk
grub> root (hd0,0)

Initialize grub onto the 1st harddisk
grub> setup (hd0)

Do the same for the 2nd harddisk
grub> root (hd1,0)
grub> setup (hd1)

Exit the grub menu –
grub> exit

Reboot the system and your grub should behave normally now..

Enjoy

From the Badlands to the Hardlands and finally to the Promised Land. 18 October 2008

Hmm..

My retirement seems to be quite short-lived. I thought I’m gonna retire from the so called promised land. Well, I did retire.. Thought of taking up agricultural activities, then the economy gone south.

Turns out, the promised land is a Hardland. Well, I’m a former Badlander. At first, I thought I can hack it. Hack it I did! 3 years!.. or somewhere close to it! The results? Diabetic, Low Blood Pressure or somewhere close to it too đŸ˜‰

The advise is to retire đŸ˜‰ as if that is possible. Nope, it’s just that I need to be mindful of myself, my health and ultimately, all those who have a claim on my life (The spouse, the Inhouse Celebrity).

Then, I got head-hunted again! First from a Japanese Electronics Giantâ„¢, but they balked at my physical conditions. My suspicions is more due to my academics, being a graduate of the Jedi Academy (or maybe the Starfleet Academy ;-). Then, it’s an American Technology Giantâ„¢ (purportedly to be the largest in the world! It’s true!). Now, these guys didn’t even care about my formal background, just so I can demonstrate my abilities.

Heh! Use the force Luke!

I am grateful to be given an opportunity with the American Technology Giantâ„¢. Now I truly believe I am in the promised land. I sincerely believe I may just retire here instead… Professionally of course.. The union-like work environment. The superb benefits package, especially medical, hospitalization which covers spouse and children, unlimited mind you! All these does help nudging me towards my decision.

Wish me luck!
