I have installed Linux and Windows XP on my hard drive and am trying to
set up a dual boot. Unfortunately XP is installed at a high sector,
namely block 204438565. The partition table starts:
Device Boot Start End Blocks Id System
/dev/sda1 63 2040254 1020096 83 Linux
/dev/sda2 2040255 104438564 51199155 83 Linux
/dev/sda3 * 104438565 206836874 51199155 b W95 FAT32
...
I have set up grub.conf as follows:
...
title Windows
rootnoverify (hd0,2)
chainloader +1
The grub initialization screen starts OK, but when I select Windows,
grub fails with a disk read error.
Questions:
(1) Is grub.conf set up right for this partition table?
(2) Is it possible to boot XP at this location, or do I have to
reinstall Linux and XP with their partition reversed, so as to get the
XP partition to a smaller block number?
(3) Is there some quicker way to get the partitions reversed other than
reinstallation?

Hi David,
I'm trying to triple boot Fedora 10, XP-64 bit, and xp-32 bit.
I installed XP-32 bit, XP-64 bit (at this point, I could see both the Os in boot menu).
Then I installed Fedora 10. However, after this, I could only see Fedora-10. Editing
Grub.conf (from many suggestions) didn't help.
Keep getting device read error messages. Then I bumped to ur post. Now, I'm a newbie
in "parted". I was hoping if you could provide me some pointers, if it is useful
at all for me:
running parted for my machine:

Looks good to me.
(2) Is it possible to boot XP at this location, or do I have to

XP partition to a smaller block number?
You wouldn't have to reinstall, but you don't need to.
(3) Is there some quicker way to get the partitions reversed other
than
reinstallation?
You *could* image out the partitions, then back in as you wish. You
don't need to though, mount the windows partition, show us what's in the
root. Also, paste the exact grub error.
Lastly, what was your install order, how did you install windows?

I read somewhere that windows needs to be the first partition to boot
properly. So you may try installing windows at hd0,0 and try again.

Hi Vinay
We must keep in mind that this list is for discussion of *Fedora*
issues (and you do not mention any problem inside Fedora itself) so
shifting focus to other operating systems (OS) could become
inappropriate in this forum. My previous post was to make a specific
point that counter to common advice I'd found it unnecessary to
install multiple OS in a specific physical order on disk as often
stated, if one is prepared to rearrange the partition table (and
repair the mbr) afterward. I felt this might be useful to primarily
linux users who might want to try install another OS after. But this
is not your situation here, you have installed your XP's first. So I
think my previous post is not relevant to you at all.
I have zero experience with or interest in XP and its installation
scripts. Also, I do not use lvm, I have not seen a grub.conf for an
lvm system. So your situation is beyond me in several aspects and I
expect there will be other readers here who can assist you better than
I. Having said that, here's my suggestions.
Your situation is different to the original poster, so it is a good
idea to begin a new thread rather than hijacking this one onto your
issue.
I think parted is not the solution you need; I suggest you focus on
grub. It is powerful and if configured correctly should be able to
boot your other OS.
However some of these other OS seem to be written assuming they are
the only OS on the box. A quick google/linux search "boot logical
partition" for similar situation to yours, first result thread [1]
included:
-----
If you _must_ get this grub setup to work, I suspect you'll have to
find some way to overcome XP's "code tracking" features that maintains
guids and timestamps (and who knows what else) about the boot loader
code/files in the registry. The code you copied no longer matches up
with what XP's registry values say it should be.
-----
So there might be other (non-Fedora) issues for you to research
elsewhere, even if you do get those OS to boot.
The reason I did that search is that it looked odd to me that you have
only one primary partition after your two XP installs, and that your
extended/logical partitions are physically first on the drive. Here
I've always used a primary partition for each OS, but maybe thats not
necessary. Other readers might confirm what is normal for multiple XP
installs.
Editing Grub.conf (from many suggestions) didn't help.
What
forum was that discussion? Can you provide a link, to save us
going over the same here?
If you want to seek help here getting your Fedora install grub to boot
those other OS, it will help to know:
1) In parted output, which partition is XP32 ?
2) In parted output, which partition is XP64 ?
3) Your entire grub.conf
4) (Your parted info again if you start a new thread).
5) The *exact* error message you see in each failed boot situation.
Good luck with it. At least you have the best of the 3 OS running ok ;)

I don't know about HAVE TO, but I've always installed XP on the first
partition and never had a problem dual booting.

It would be helpful to see your grub.conf file. Did you try

I read somewhere that windows needs to be the first partition to boot
properly. So you may try installing windows at hd0,0 and try again.
Jonathan, I may have better news:
It is widely-quoted advice that (#1): a Windows boot partition must be
the first partition on the drive. Most advice suggests installing
Windows first. I found this annoying in several scenarios.
However recent problem solving activity on this machine led me to
experiment and discover that while this is close to the truth, it is a
"sufficient" but not "necessary" condition.
What apparently _is_ essential for the Windows boot loader is
specifically that (#2): the Windows boot partition is the first entry
in the drive partition table.
In most situations without intervention, the requirement (#2) is
achieved as a consequence of (#1). However, in a situation where the
first partition on the drive is already in use, I have found it is
possible to install Windows on a higher numbered partition and then
delete and recreate the parition table entries in the correct order.
For example, I did this on the hard drive on this box, it currently
has 3 bootable partitions: Windows 2000, MSDOS, and Fedora 9 shown
below.
The following parted output shows each partition in its physical
sequence by ascending "Start" sector number. Note that the "Number"
column (= the order in which the partition table entries were created)
is not in the same order.
3=\boot
2=MSDOS
1=Windows 2000
4=extended partition containing logical partitions 5,6,7,8
5=FAT32
6=swap
7=\
8=\home

8 36017793s 39102209s 3084417s logical ext3
I achieved this by first installing Fedora 9 with blank spaces for the
fat partitions, and then by hiding each previously installed primary
partitions while installing the next OS. This achieved the physical
sequence on the drive as shown above, but with parition numbers in
ascending order. If I recall correctly, at this point Windows would
not boot. I then made a note of all the start and end sector data, and
then used parted commands "rm" and "mkpart" and "set" to
delete and
recreate the partition table shown above.
Why bother? So I can start both Windows and MSDOS from /boot/grub
without using Windows ntldr.
I kept the \boot and MSDOS partitions small, so that the start of the
Windows partition was not too far from the start of the drive. I have
not tested a scenario where this is not the case, and would be very
interested to hear back from you to further my knowledge if grub is
able to directly boot Windows in your situation.
Its also necessary to hide the two Micro$oft operating sytems from
each other; I achieve this in /boot/grub/grub.conf as follows:
title Windows 2000
hide (hd0,1)
unhide (hd0,0)
rootnoverify (hd0,0)
makeactive
chainloader +1
title MSDOS 6.20
hide (hd0,0)
unhide (hd0,1)
rootnoverify (hd0,1)
makeactive
chainloader +1
If you have only one Micro$oft OS then this may not be necessary.
At some point you may encounter grub having trouble locating the
correct boot partition. So before you start ensure that you an
alternative method of booting into linux in case your hdd grub fails.
Then use that to boot and reinstall grub, see "info grub". Once I had
a paper record of the parition table, I didnt lose any data in this
situation.
Warning: fiddling with the partition table can result in data on the
drive becoming inaccessible. Do not attempt any of this this unless
you are confident and have backups. You will need or develop a strong
knowledge of parted and grub. But if you are that way inclined I knew
nothing when I started and was able to achieve what I desired.
Hope this helps, David
