CJS

the bootloader is still the windows bootloader that is linked at mbr. I believe the original question is up to bmosov01...to answer....but he may need to read how to use a rescue cd first...and howto fixmbr for windows in case he puts grub into mbr.

bmosov01

forgive me for any pressure you may feel but here are the 2 alternatives for you

bios jumps to mbr to find bootable partition ->
either windows or linux is linked to mbr but not both

a)

install grub to mbr


boot live cd
Code:
su
root (hd0,1) 
setup (hd0)
quit

you MUST see a end line that says succeeded...meaning mbr has a stage1 grub file that is linked to jump to balance of booting files at sda2....grub counts from zero



reboot computer



------------------
since I can not easily explain that non-visually let revisit your linux entry
-----------------
title Ubuntu 8.10, kernel 2.6.27-7-generic
uuid 7ef466f2-9561-4b3f-9391-a2ed54e387de
kernel /vmlinuz-2.6.27-7-generic root=UUID=ba79e001-bf29-43d1-9a69-50aae1d475ed ro quiet splash
initrd /initrd.img-2.6.27-7-generic
quiet
----------------------------------------------------

The uuid entries must match the other entries you have posted for UUID

----------------------------------
and your uuid entry shows

/dev/sda2: UUID="7ef466f2-9561-4b3f-9391-a2ed54e387de" SEC_TYPE="ext2" TYPE="ext3"

/dev/sda5: UUID="ba79e001-bf29-43d1-9a69-50aae1d475ed" SEC_TYPE="ext2" TYPE="ext3"

so the first mention of UUID takes grub to a partition called sda2 and that is correct

the second mention of UUID says root = (sda5) and that appears to be correct.

As you have a separate /boot partition to / partition.

Please report if you remember not doing this?

SO altho I do not like Ubuntu...etc...this entry may work as is.


b) but typical of ubuntu they have made the chainloader command section too messy

here it again.
----------------------------
# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title Microsoft Windows XP Professional
root (hd0,0)
savedefault
chainloader +1


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda2
title Windows NT/2000/XP
root (hd0,1)
savedefault
chainloader +1
-------------------------------------------

Can I ask that when you reboot...boot into linux first then get root powers and delete those lines called
savedefault

what savedefault does is ...treat you like an idiot....and so when you boot into sda1.....it makes that the new default for all new reboots...and we would like you to learn more about linux!!

SECOND whine is ubuntu has stuffed up and decided to create an sda2 entry for windows not realising its a linux partition..so delete that entry please


b)

This option is if you decide not to put grub into mbr but chainload it from windows

1) redo grub for its root=boot partition

boot live cd
Code:
su
root (hd0,1) 
setup (hd0,1)
quit
last line must say succeeded to hd0,1

2) then follow the steps in my signature to take a image of that new (almost mbr like part of /boot partition.....

reboot to windows and edit your bootloader to chainload it

Ok, so I kind of got fed up with this and decided to just install grub to the mbr...I repartitioned my hard drive from what i had before and just used the default option to install grub in hd0, and magically everything seems to work. I spoke with some people who said that if I have the backup cd's I made from the service partition, then I really don't need it anymore anyway, so there's no need to go through all this hassle to try and make a separate /boot partition instead of overwriting the mbr (since the only reason I was doing this was to maintain access to the service partition). Anyway, after running through the install again and installing one or two recommended drivers (for the discrete graphics and trackpoint scrolling features) everything seems to be working fine. I just switched the order of my titles in the menu.lst file and so even configured the grub menu with the correct default OS (windows) and my preferred order in the menu. So I guess that's that.

Again, thanks to everyone who helped. It was a frustrating couple of days (more like a week I guess) but I learned a lot about what goes on when you boot a computer and what goes into installing Linux, so hopefully that will help me along the way. Take care.
