dual-boot problem with windows 2000 using grub boot loader

mojo_jojo · 01-10-2008, 02:55 AM

hi,

i have a problem booting my windows 2000. i recently installed a redhat linux using grub as my boot loader. i only have one hard disk (80G)with three partitions. the boot.ini and ntldr are in drive c while the winnt folder is in drive e (extended partition). i set drive d for my redhat linux installation. during linux installation, i set my partitions as:

#fdisk -l
/dev/hda1 fat32 drive c:
/dev/hda2 ext'd
/dev/hda5 ntfs drive e:
/dev/hda6 linux /boot
/dev/hda7 linux swap
/dev/hda8 linux /root

#my grub.conf
title red hat enterprise linux
root (hd0,5)
kernel /vmlinuz-2.6.18-53.el5 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.18-53.el5.img
title windows
rootnoverify (hd0,4)
chainloader +1

once i boot to windows..it gives an error "ntldr is missing"
but when i change the grub config for windows [rootnoverify (hd0,0)]
the windows cannot locate the ntoskrnl.exe in system32 because my winnt folder is in drive e: while the boot.ini and ntldr resides in drive c:

can anybody help me with this?

wow...the only thing i could think to try would be booting in linux, or with a dos recovery disk and copy ntldr onto the c: and see if that works...

Run the command again with a Linux Live CD.

Code:

fdisk -l

You should have a bootable (active) partition, which is indicated by an asterisk (*). This is my partition table

Code:

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1        1275    10241406   83  Linux
/dev/hda2            1276        1406     1052257+  82  Linux swap
/dev/hda3            1407        4865    27784417+  83  Linux

If that doesn't help, then perhaps the attached tutorial can.

I think "rootnoverify (hd0,4)" needs to be "rootnoverify (hd0,1)", assuming the Windows boot is on the dos partition (partition 1). If that doesn't work changes "rootnoverify (hd0,3), if the boot program is on partition number 3.

You know you can edit the grub lines by moving the cursor (using arrow keys) over the "Windows" and hitting the "e" key (for edit). Then you can move the cursor around to the line you want to edit and moving the cursor around.

Also delete the "quiet" on the "kernel" line. You can watch the Linux kernel boot.

These edits are temporary. Once you get it working you will have to go edit the grub file to make it permanent. Partition numbers start at zero in GRUB instead of one. See the pdf that was sent in the previous post.

Good luck.
