Question dual boot problems


I have two HDD's in my computer i have RH 8.0 installed on my master and win98 SE on my slave....linux boots fine with GRUB but when i try to boot windows, the screen goes blank and shows:

booting 'win98'

rootnoverify (hd1,0)
chainloader +1

and does nothing after that. But i can get into win98 by going into the BIOS and telling it to boot from my slave HDD. Can someone please tell me what i need to do to boot win98 from GRUB?

For any win9x OS you need to have it as the primary master (or simply the first booting hdd) on the chain. You should put the 98 hdd as master and then you might need to reconfigure linux using your boot floppy you should be able to edit lilo and reconfigure linux properly. Otherwise you can just reinstall linux. You might have to do a fdisk /mbr once you have the 98 drive as the first drive to get it to boot into 98.

In the Grub manual there are instruction for remapping your drives; you put commands in Grub that tell it to treat your primary drive as a slave and your slave drive as the primary. They are very straight forward and easy to add. It will save you from swapping drives and reconfiguring/reinstalling Linux.

To find the Grub manual, type "Grub" in the search window at www.google.com/linux

Good luck

I'm just a newbie in Linux (redhat 7.x). I have the same problem, I used C: Windows XP, F: Linux. And the machine can't boot Window XP, whatever it always boots Redhat 7.x
I'm just a new bie. Can you solve me how to return to Windows XP? I still don't know how to fdish /mbr

I have the problem that many people used to do. I'd like to use 2 OS in a computer (OS Linux Redhat 7.x and OS $WinXP)

I used winXP in my computer, then I installed Redhat 7.x. The result the system can't boot OS winXP. Instead Redhat always runs when the machine turn on. I changed BIOS to run winXP but nothing is effective.

In my case, I used C: to due WinXP and F: for Linux.
Does anyone here help me, I can't run winXP anymore. My winXp keep my data, I don't care to lose Linux to install again. ( i don't have my Windows XP bootdisk, I lost it somewhere)
I'm a newbie in Linux.
No, I didn't know how to figure this problem. I'm an idiot. Can anyone help me?

what you need is any windows boot disk with the fdisk program on it. Boot up with the floppy disk and at the command prompt type:
fdisk /mbr
what this does is erase the master boot record where your redhat lilo should reside and therefore remove it and allow you to once again get into winXP.

yes you will have to reinstall whatever boot manager you want to use onto the mbr after you do the fdisk /mbr

weird, weird, weird..!
I can't issue any damn DOS commands, because all but "S" key is down. I can't type fdisk, because there is no "s" when I am in DOS! Bah! Is there a vaccine for that?

The problem is that after installing XP ( I need it just for the modem to work!), I can't boot into XP, but only linux. Do you edit MBR by hand?

Did you try to boot from a standard DOS floppy disk that you created, and does the "s" key work in linux properly or is it something bigger than the OS.

The problem is that there is no floppy, but there is DOS on the CDRom, and that did not work.

Anyway, the prolem is solved: I reinstalled (upgraded) Mandrake, and the boot record for Windows was restored.

It is really true what the folks tell: if you dual boot, first install the M$, and then Linux.

P.S. The modem doesn't work anyway. Not under Windzoo nor under Linux. Pazienza.... But what a rubbish the windows is!! It's increadible! I recently booted back into Winzdoo after several months of linuxing and I was astonished. I just can't believe I was able to use Winzdox for so long! All the best.
