Need help with GRUB boot loader

[jj1492]

Ok, here's the situation. I have one HD. I installed Windows 2000 on one partition, installed Windows XP on another, and then installed RedHat 7.2 on the remaining space. I specified GRUB as the boot loader. I have it set to boot into X (init 5), but my display settings won't work and my monitor cuts off (Leadtek Geforce3 Ti200 and 17"Gateway Monitor). So my questions are:

1. How do I change my init level so I can edit my display settings?
2. How do I change my display settings?
3. How do I add my Windows partitions to the GRUB boot loader?

Thanks in advance!

When the grub boot screen comes up pick the Linux entry, press 'e', then select the kernel line (should start /blah/vmlinux-blah root=/dev/blah) and hit 'e' then arrow over to the end of the line and add '3' (no quotes), press enter then 'b' to boot, it should boot up to runlevel 3 so you can fix X.

Either edit /etc/X11/XF86Config-4 (might not have a -4 at the end) by hand or run XFree86 -configure to have it autogenerate a new config file, copy that over /etc/X11/XF86Config-4 and see if X works better.

Alright, I got to init3, and ran the XFree86 -configure. It creates a new file, but when I do a rename XF86Config.new XF86Config-4, it doesn't work... it doesn't rename the file. So right now, I don't have an XF86Config-4 file, which I apparently need... what now? Thanks again.

The command to rename a file in linux is 'mv' for move.

You are the man (though I feel like I should have known that). So my last question is how do I get my Windows partitions on the GRUB menu to boot with?

--edit-- acutally i don't think i should be giving advise till i know what i'm doin

you have to edit /boot/grub/grub.conf

or theres a link /etc/grub.conf

it has all the things
title Red Hat Linux (2.4.7-10)
root (hd0,6)
kernel /vmg;alkhr;lakh
initrd blah blah
title Red Hat Linux (2.4.10)
root (hd0,6)
kernel /vmlinuz........
initrd.....
title Windows XP
rootnoverify (hd0,0)
chainloader +1

--

thats the end of mine... i didn't type out all the linux ones
dunno if chainloader +1 goes with the xp thing or if its at the end of the file
i'm guessing its hd0=drive and 0=partition you want it to boot to

I just messed around to add new linux kernels, didn't have to add the winxp

To add Windows to the Grub menu you'll need to edit the menu.lst file which you should find in /boot/grub.

The entry for Windows should look something like this:

title = Windows
root = (hd0,0)
makeactive
chainloader +1


The root entry in this case is for a Windows install on the primary partition of the primary master drive. For more detailed info on Grub open a terminal and read its manual pages (man grub)

Some pretty good, concise info on Grub can also be found here.
