Win2k Stole Boot...

I installed Red Hat 9 with the Grub boot loader a little ways back...I did a full install, and made sure to create a boot disk.

Later, I installed Win2k. It (of course) stole the boot.

Now, when I try to change the "active partition" back to the Grub partition, it doesn't boot at all. When I use the boot floppy I made, it can't find Linux at all.

Can anyone offer some suggestions, or point me to somewhere, on how to fix this? Is it possible to fix this without completely reinstalling Linux? If I have to do a complete reinstall, I don't mind...but if there's another way, it may help down the road. I tend to install and remove OS's alot...

Thanks in advance,
Doug Burkhalter

Re: Win2k Stole Boot...

I do not master this, but I'll try to help.

Personally, I have two hard disks, windows in primary master (hda) and linux in primary slave (hdb). When I install linux the bootloader (lilo in my case) installs by default in the primary master (hda), regardless of having linux in the primary slave. I have to manually state in the installation process that I want lilo in the primary slave (hdb), then configure the bios setup to boot from the primary slave. This way, windows can do whatever he wants to with his hard disk, it will never put my bootloader at risk.

This is all refering to mandrake, and it was mostly an advice as how to do this in the future. But as to fix what you have already done, I don't know RedHat, but Mandrake install CD has an option at boot, when you type the kind of installation you want, and one of the options available is a rescue install, which does not install anything, but brings up a menu of bootloader related actions, such as install a bootloader in any desired harddisk, delete a bootloader, etc. If RedHat doesn't have this option, I don't know. You could try to ask this question in the RedHat distribution Forum here in LQ, or try and see if the mandrake CD options work with a RedHat install, if you can manage to have a mandrake CD. If you do this and works, please, let me know.

RedHat's Repair System

Well, I can't get my hands on a Mandrake CD right now (actually, I have a copy of Mandrake move, but I highly doubt it contains the installation and rescue routines), but you gave me a good idea - I checked and my Red Hat disk does, in fact, have a rescue system on it!

It wound up doing the trick, at least as far as letting me get into my system. After that, I ran grub-install to put install back onto the drive how it's supposed to be (into the MBR). However, it didn't work right; the screen comes up all wrong, and the boot options don't work.

I think that, with a little tweaking, I could get it to work right. But it's easier to just reinstall Linux right now, since I hadn't done too much in the way of customization.

I wish I could do two harddrives, but the way my case is (mind you, that's the only problem, the case...well, and maybe the power supply...but that could be fixed by a simple molex splitter) it can only hold 3 3.5in I've got my Hard drive (a 120 gig one), floppy drive, and internal USB hub (man, I love that thing!) taking up all the spaces....and I've seen some horrors caused by hard drives not properly in the case (ever seen a magnatized hard drive? they're fun to play with, but don't boot I actually have a spare 15gig hard drive (and a half-gig...), but i'm wary to just leave it lying around in there, not in a proper spot...

At any rate, I just might be able to fix it if it happens again...with a little patience.

PS: if anyone has other suggestions, feel free to post them. I'd be willing to be this will happen to me again; at any rate, it's bound to happen to someone else.
