 Posted: Tue May 27, 2003 4:26 am Post subject: make W2K bootloader boot grub |
 |
|
there's this trick possible with lilo that could make the lilo bootloader accessible from the W2k bootloader :
dd if=/dev/hdpartition_with_lilo of=somefile bs=512 count=1
and then place somefile into the windows partition and reference it from
boot.ini
question is, is there something like this for grub ?
I prefer keeping the W2k bootloader in /dev/hda1 because it is
less flexible than lilo. less screwups when reinstalling windows. |

Yes. For details check out the Documentation tip's & tricks forum. There are several threads about gentoo & WinXP/2K. I know it's in there. Also have you tried doing it the other way around? Set the partition with grub as the active partition & boot windows from grub.

thanks for the tip ! found the topic.
I did what it said and it gave me :
does anybody have a definite solution for this ?
never tried changing the active partition. I've read that creates problems
for W2k. I did try to swap disks, both physically (fiddling with the cables)
and from the bios. They work but they feel like broken solutions !  |

Thanks. I've done that with LILO and SuSE before.
I'm trying to do it with GRUB.
following the faq at : https://forums.gentoo.org/viewtopic.php?p=190205
(IG2: How to install Gentoo in a Win XP/NT config)
which says :
| Code: | grub> root (hd0,4)
grub> setup (hd0,4)
grub> quit |
There are certain are warning messages right after I do setup (hd1,1).
something about failure to embed stage 1.5
I then do the dd stuff and then copy the 512 byte file to W2k
and then refer it in boot.ini.
when I reboot and select gentoo from the w2k bootloader
I still get the "GRUB _" hang.
it's the same problem discussed here :
https://forums.gentoo.org/viewtopic.php?t=27777
([SOLVED] Killed my GRUB, don't know how...) |

If you are using 2 harddrives with linux on the secondary drive and windows on primary your setup command should be:
setup (hd1)
Which sets up the kernel on the MBR of your secondary harddrive.

Got it working !!!
Again, my setup is 2 disks, hda contains W2K on the first partition
and hdb contains my ext /boot on the first partition.
The goal was to make Gentoo bootable from W2K's bootloader.
This didn't work :
| Code: | grub> root (hd1,0)
grub> setup (hd1,0) |
There was always some error regarding the embedding of stage1.5
which grub cheerfully says is not fatal.
What I did instead was followed the help instruction ('help install' at the
grub prompt) :
| Code: | #mount /boot
grub> root (hd1,0)
grub> install --stage2=/boot/grub/stage2 /boot/grub/stage1 d (hd1,0) /boot/grub/stage2
grub> quit |
afterwards I did the same thing as the before :
| Code: | #cd /
#mount -t vfat /dev/hda1 /mnt/A1
#dd if=/dev/hdb1 of=bootsect.gnt bs=512 count=1
#mv bootsect.gnt /mnt/A1 |
and then modified boot.ini to refer to bootsect.gnt :
| Code: | [boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect
C:\bootsect.gnt="Gentoo" |
I think the crucial thing was I specified the "d" option
and I think the --stage2 option could be omitted in the install command :
| Code: | grub> install --stage2=/boot/grub/stage2 /boot/grub/stage1 d (hd1,0) /boot/grub/stage2
