ntfs partition no more visible from windows after linux install

Hi all,
I have been installing linux twice (Mdk, Suse) on a XP system and had twice the same pb. I lost visibility on a non bootable partition from windows.

Initial configuration is the following:
1st hd - two partitions, FAT32 and NTFS
2nd hd - one NTFS partition and free space

I let the installer partition the disk for install on the second disk. Once installation is done, everything works fine with linux. But I can't access the NTFS partition on the second disk from windows anymore :confused: XP states that this partition is MBR and needs to be formated :mad:

Running cfdisk does not show anything weird. Types seems correct but as far as I can tell.

First time I had the problem, I tried to fix the boot sector with the windows console ... but it ended in a big mess, a reformat and restore of the files :D

Does anyone have a clue?

Thanks for the help

PS: may be it is more a windows issue but I really want to go for linux - hope this will give me some credit
:rolleyes:

can you give some details of your fdisk/cfdisk result?
can you mount the partition from Linux?

yes I can mount the partition from linux. This is how I retrieved windows data I had not backuped yet.
outcome of fdisk/cfdisk is the following - sorry it is in french :study: )
Amorce = boot
Début = Begin
Fin = End
tete = head
Aucun = none
libre = free
I guess that the other terms are undestandable for english spoken people.

Code:

fdisk -l

cfdisk gives similar display, except that it mentions that hdb1 has a label (no clear text : "[^O]" without the quotes)
I add a print of the partition table in raw format and in sector order format (no idea if this is useful to put both :confused: )

I can't see anything weird. What has changed that causes XP to see a bootable partion where linux doesn't see any??

Last action was too check with XP console utility diskpart. No more hope, windows does simply not recognize my partition. Reformat is threatening :p
What surprises me is that I seem to be rather alone to have the problem. May be related to my configuration and/or NTFS? Did anyone experience something similar or at least have an opinion about it?

You could mount it & bckup? it should be ok then....
are you sure your XP didn't recognize it?
try to see it from Computer Management Console
Start --> Run --> compmgmt.msc....
you should find the storage section....
and find partitions there.........
try to find your missing partition there, try to change its drive letters
hope it works....
