Hi everyone!
bit of a noob round here so please go easy on me:)
Yesterday i installed ubuntu 8, i had to manually edit the partitions as i have 5 hard disks - 3 sata and 1 ide, my windows drive is a sata and was plugged into sata2 on my motherboard so it was not the default drive for the partition tool to auto edit during install.
so i reduced the windows partition and set up an ext filesystem and a swap area, installed ubuntu with no further errors.
However grub didn't pick up the windows partition and when i manually edited it to point toward where the windows partition should be it has "Error 12: invalid device requested" i was a bit upset about this obviously as i can no longer boot into windows!!! i have unplugged all other drives except the main drive and plugged it into sata1 on the motherboard, so now i can boot into Ubuntu no problems but still no windows!
ok i ran the windows install disk and went to recovery mode, the diskpart tool there gave me this:
-:partition1 (windowsxp fault tolera)
c:partition2
f:partition3
chkdsk sais "volume appears to contain one or more unrecoverable problems"
and fixboot gives BSOD!!
then, i boot into ubuntu and run the following disk looky at type commands i've picked out of other posts:

Gparted shows the first partition as having an unknown filesystem and the partition is inaccssable through ubuntu either?!? it is unable to mount:
dan@dans-ubuntu:~$ sudo mount /dev/sda1
NTFS signature is missing.
Failed to mount '/dev/sda1': Invalid argument
The device '/dev/sda1' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
dan@dans-ubuntu:~$
i really am not sure what i can do about this? i don't really understand all this output but from what i can gather somehow the disk label for partition 1 is corrupted? or missing?
any and all opinions and ideas encouraged:)
thanx! dan
