Commands to reinstall the GRUB
 

Hi friends,

I have Windows 2000 Professional on my C drive and Red Hat 9 Linux on my E drive. I am about to remove Windows 2000 Professional and do a clean install of Windows XP Professional. I know that Windows XP will overwrite the Linux GRUB (the boot loader on my computer).

I need the commands through which I can bring or reinstall the GRUB back. I have all the three Red Hat 9 Linux CDs.

Detailed instructions and steps on this will be much appreciated. Please keep in mind that I am totally new to Linux. So, detailed instructions would be useful to me.


Thanks & Regards

so you installed GRUB into MBR or what? :) man, the first mistake one can do if there's windows on the same HD..ok, enough of joking. There should be the Grub RPM package(s) on some of the redhat cds, altough I don't know on which one...you'll just have to search. but first things first.

make a bootable floppy so that you can boot your linux after the reinstallation of windoze..RH has some GUI tool for that I think. after that do the reinstallation of windoze, boot from the floppy, mount cdroms, search for an rpm-package for GRUB (like grub-x.xx.rpm where x.xx is the version number) and install it. the installation was something like

rpm -ivh grub-whatever.rpm
OR
rpm -Uvh grub-whatever.rpm

I'm not sure about the rpm command...but if you use GUI, double-clicking the file should do.

HI b0uncer,

That is not what I am referring to, there are some commands through which you can reinstall the GRUB.

That's when you insert the Disk 1 and type at the boot promt something this:

linux rescue and press enter and then carry on something....


Don't know much on this.

Any ideas.

Boot the 1st CD into rescue mode. i.e type rescue at the prompt. Your root partition will be mounted at /mnt/sysimage. Enter the following commands:

chroot /mnt/sysimage
grub-install

BTW Did you search the forum first before asking?
