 Posted: Fri Aug 29, 2003 11:17 am Post subject: HOWTO: Installing Gentoo with Windows XP |
 |
|
A lot of you guys (including me) had problems installing Windows XP with Gentoo using GRUB, here is a working configuration. I am writing these steps from my memory, so please confirm each step as you use them whether they are correct so that this can go to the Documentation, Tips & Tricks section later.
If you want to install Windows on a different HDD than Gentoo, you can jump down and just look into the grub.conf and use the map instructions at the section 'Windows XP Casual'
If you want to install Windows on on the same HDD follow these steps:
First of all you have to install Windows, the critical step is to put it on the first partition or create a small partition for its boot binaries, this is very IMPORTANT! Windows can't boot if its binaries are not on the first partition. I didnt know this when I was installing my system, this so I had to give up my linux boot partition for Windows. 
On my system I have 7 partitions now, 1 boot partition, 1 swap, 3 equally sized for Gentoo, 1 NTFS for Windows and 1 FAT32 for sharing files between Windows and Gentoo's.
| Code: |
Disk /dev/hda: 81.9 GB, 81964302336 bytes
255 heads, 63 sectors/track, 9964 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 4 32098+ 4 FAT16 <32M
/dev/hda2 5 9964 80003700 f Win95 Ext'd (LBA)
/dev/hda5 5 69 522081 82 Linux swap
/dev/hda6 70 1374 10482381 83 Linux
/dev/hda7 1375 2679 10482381 83 Linux
/dev/hda8 2680 3984 10482381 83 Linux
/dev/hda9 * 3985 5942 15727603+ 7 HPFS/NTFS
/dev/hda10 5943 9964 32306683+ b Win95 FAT32
|
If I I were you, I would create a boot partition for Windows and a boot partition for Linux separately (for security reasons)
| Code: |
Device Boot Id System Size
/dev/hda1 4 FAT16 <32M 8 MB - I think this is the smallest possible
/dev/hda2 f Win95 Ext'd (LBA) This is the extended partition
/dev/hda5 83 Linux 32 MB - Linux boot partition
/dev/hda6 82 Linux swap ? MB - Your swap (I use 512 MB)
/dev/hda7 83 Linux ? MB - Linux (I use 10 GB)
/dev/hda8 83 Linux ? MB - Linux (I use 10 GB)
/dev/hda9 83 Linux ? MB - Linux (I use 10 GB)
/dev/hda10 7 HPFS/NTFS ? MB - Windows (I use 15 GB)
/dev/hda11 b Win95 FAT32 ? MB - Windows (I use 32 GB)
|
If I remember correctly I created the partition with Gentoo's fdisk and then rebooted and installed Windows on the drive H:
Before installing Gentoo you might want to save your boot sector and your Windows boot partition
| Code: |
dd if=/dev/hda bs=512 count=1 of=/mnt/destinationpartition/mbr.BIN
dd if=/dev/hda1 of=/mnt/destinationpartition/WinBoot.BIN
|
Install Gentoo 
Configure grub to use the mbr (we want to use GRUB as the loader not the Windows  )
| Code: |
grub
grub> root (hd0,5) (Your boot partition)
grub> setup (hd0) (Where the boot record is installed; here, it is the MBR)
|
Here is my grub.conf:
(Don't just copy, substitute for your partition names hda5, hda6 etc.)
| Code: |
# Boot automatically after 30 secs.
timeout 5
# By default, boot the first entry.
default 2
# Fallback to the second entry.
fallback 1
splashimage=(hd0,5)/boot/grub/splash.xpm.gz
# For booting GNU/Linux
title Gentoo
root (hd0,5)
kernel (hd0,5)/boot/bzImage root=/dev/hda6
# For booting Backup GNU/Linux
title Gentoo-BACKUP
root (hd0,7)
kernel (hd0,7)/boot/bzImage root=/dev/hda8
# For booting XP GNU/Linux
title Gentoo-XPeriment
root (hd0,6)
kernel (hd0,6)/boot/bzImage root=/dev/hda7
# For booting Windows XP
# This Windows resides on the same HDD (hd0)
title Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1
# For booting Windows XP
# This Windows resides on a different HDD (hd1)
title Windows XP Casual
# *Caution:* This is effective only if DOS (or Windows) uses BIOS to
# access the swapped disks. If that OS uses a special driver for the
# disks, this probably won't work.
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd0,0)
makeactive
chainloader +1

I hope it helps

Hi...
maby you can help me a little
I have Windows XP currently installed on this box i am writing from now, and i want Gentoo on this box, but i want to keep windows xp so that i can play CC- generals. (the only game i play)
this is what my harddisk looks like:
Start{
4.4 gb space for windowsXp
90 gb for backup
10 gb unpartitioned space
}
i want to install Gentoo on the last 10 gb, but i am afraid of installing the grub on the partition that windows uses.
what should my root (hd0,0) be ?
and what about setup (hd0) ?
EDIT:
Well.... i think that i just should overwrite the windows MBR, and then just make a link to the windows xp partition.
what is chainloader ?

first do fidsk -l /dev/hda
then find there which is your linux partition
if it is hda3 then your root should be
root (hd0,2)
setup (hd0)
if its hda4 then root (hd0,3) etc.
if you do info grub you will find it there as:
| Quote: |
- Command: chainloader [`--force'] file
Load FILE as a chain-loader. Like any other file loaded by the
filesystem code, it can use the blocklist notation to grab the
first sector of the current partition with `+1'. If you specify the
option `--force', then load FILE forcibly, whether it has a
correct signature or not. This is required when you want to load a
defective boot loader, such as SCO UnixWare 7.1 (*note SCO
UnixWare:.
|
I dont understand what do you mean by linking to your partition but
what actually grub does is it executes the code found on that +1 sector instead of using your linux kernel |
