How to edit Grub?
« on: June 17, 2007, 04:03:19 am »

Hi, just installed Vector Linux and installed grub..
After that grub gives me error 17 on loading, I know this problem as Ive already experienced this before..

My pc is running through a sata contoller therefore the harddisks are referred to as (sda, sdb, sdc) instead of hd0 which is set as default for GRUB.. All I need to do is change "hd0" to "sda",.. How do I edit GRUB now? First of all, I cant find the grub.conf file anywhere, like it didnt install.. all I found was vgrubconf or something resembling that that I couldnt edit through the Vector Linux livecd which is the only working livecd i have right now.

Somebody please help me edit Grub.conf and get this over with coz I'm stuck at error 17, thanks..

grub.conf is usually just a symlink to menu.lst (which is the actual config file), it should be in /boot/grub, hope it helps. :D

As root, you can type mcedit menu.lst and modify the file.

Everytime I try to edit the file with nano it tells me it saves but the saved changes dont appear when I check the file again
It is still error 17 like I didnt do anything.. And there are a few files like menu.lst.save and menu.lst.save.1.. What the hell is going on?
In the beginning it says its generated by the vgrubconf file. How do I edit that? Grub sucks, please help!

I'm not positive, but I think you can just overwrite GRUB in the Master Boot Record with LILO.

yep, there is no uninstall command, you need to overwrite the mbr, i.e., install lilo over.

My grub isnt in the Master boot record.. Its only in sdb1, the partition inwhich vectorlinux is installed

Do I just delete the folder in /boot/ ?

Hello,

no, do not deleet folder /boot.

I recommend you to read file that you can find on
www.gnulinuxcentar.org/bootloader.pdf
and after that decide what you want to do with  your bootloader.

regards,

If you install into the MBR, sdb1 will be ignored. If you install into sdb1, GRUB will be overwritten.

All out epic win for LILO either way.
