[SOLVED] CentOS 5.5 boots up to grub> prompt

x81kilo · 06-04-2010, 02:24 PM

*****RESOLVED BY RE-INSTALLATION OF OS*****
First Post: I am new to linux but learning fast and am computer adept so i can follow instructions and test things as well.

Having said that, I installed CentOS 5.5 last night, and with instructions,

Since it was 3am, I decided to do a shutdown -h now and go to sleep.

Just woke up to see my nixbox loading up to grub> prompt.

I Have no idea how to fix....can anyone help?

Thanks in advance,

Does grub display an error message, grub will display an error message if it is unable to boot your OS e.g Error 17 or some other error.

There is a article around somewhere on how to properly ask a question.
Read it.

You've provided no information useful in us helping you.
- what instructions.
- machine (principally hard disk) configuration.
- partition layout.
- grub version (probably 0.97 on Centos).

Also, do you have a Linux liveCD handy ?. This will allow us to give you commands to provide the info above. Knoppix is as good as any.

The prompt is being displayed because grub (i.e boot loader) can not find the grub.conf file located in /boot/grub directory. Will assume that you installed CentOS using all the defaults selections. After the install was completed did the computer reboot successfully?

Resovled -- I just installed the 64 bit version of Centos and wiped everything clean.

here was my configuration

amd quadcore 4gb ram / 500 gb hdd
/boot 500 mb ext3

remainder was lvm

problem was i think that after installing the OS, installed oracle 11gR2 for my class on there, but i put the /boot into the lvm and thus created the issue. I will have to test this the next time around when we are asked to trash our boxes and reinstall from scratch OS level.

Thanks for all the posts, and yes I do have knoppix (dont recall version) which i booted into and tried to follow a few tips given to others without success.

I am now writing down stuff for future in case i happen to go thru this again....its good to write config stuff down i think.

Cheers!
