Major install problem - need some urgent help please

[Diss]

Hi all

I have a dual boot linux (dapper/xp)

i have just tried installing Edgy from the live cd by installing it over my existing dapper partitions.

I have a dual-boot Dapper/WinXP setup with 3 hard drives
hda - old 40 gig IDE
sda - 250 gig non boot drive
sdb - 200 gig dual boot drive

This was the insatll options i chose:
/media/hda1 (my IDE data disk)
/media/sdb1 (my winXP NTFS partition).............1st SATA drive
/boot (sdb2)..REFORMAT SET TO YES...........1st SATA drive
/ (sdb4)..REFORMAT SET TO YES...........1st SATA drive
swap (my swap file)..REFORMAT SET TO YES....1st SATA drive
/media/sda5 (my 2nd sata 'data' disk)

GRUB went on the default choice of (hd0)

However when i restarted i got the GRUB boot menu but i get these errors

For Edgy:
Error 22 - No such partition

For WinXP
Error 12
Invalid device requested

What is also worrying is that the /mnt and /media directories show as empty.

I think this could be sorted out by GRUB??? Any idea's what to do here?

many thanks

Diss


Edit : Are there any commands i can run from my live CD that will help diagnose stuff here?

Hi

I booted from a Knoppix live CD and can now see all my drives.

My menu.lst file looks like this:
================================================== ========
title Ubuntu, kernel 2.6.17-10-generic
root (hd2,1)
kernel /vmlinuz-2.6.17-10-generic root=/dev/sdb4 ro quiet splash
initrd /initrd.img-2.6.17-10-generic
quiet
savedefault
boot

title Ubuntu, kernel 2.6.17-10-generic (single-user mode)
root (hd2,1)
kernel /vmlinuz-2.6.17-10-generic root=/dev/sdb4 ro single
initrd /initrd.img-2.6.17-10-generic
boot

title Ubuntu, memtest86+
root (hd2,1)
kernel /memtest86+.bin
quiet
boot

### END DEBIAN AUTOMAGIC KERNELS LIST

# This is a divider, added to separate the menu items below from the Debian
# ones.

# This entry automatically added by the Debian installer for a non-linux OS

================================================== ==========
device.map is:
(hd0) /dev/hda
(hd1) /dev/sda
(hd2) /dev/sdb
================================================== ==========

There seems to be some mapping there that i don't recall from previous Dapper installation. In Dapper i had changed the mapping but i assume this was overwritten with the new install so that something else must be causing it. Any idea what?

I think that for Linux to boot it should show as:
root (hd0,1) and NOT (hd2,1)

and for WinXP
root (hd0,0) and NOT (hd2,0)

I could edit the menu.lst but am unsure about why the mapping is taking place.

Any thoughts on this?

Thanks

Doc

for info:
sdb2 = /boot partition
sdb4 = / partition
sdb1 = winXP partition
The /boot folder on sdb4 is empty

my advice would be to edit the mapping and try, got nothing to lose
