Grub and NTFS File system

[Claude GERBAUD]

Apparently GRUB is unable to boot windoze NT from a NTFS partition:

-> File system type unknown, partition type 0x7

I have a box with an adaptec 2940U2W controller an a 9 Go ultra-wide disk for Window NT And Linux . I have also a slow 30 Go IDE drive for stocking a lot of thinks !

Actually Nt boot from MBR of hd1, linux from floppy with either lilo or GRUB.
Grub is faster and it is usually used for booting linux.

Here is the fdisk report:

Disque /dev/sda : 255 têtes, 63 secteurs, 1106 cylindres
Unités = cylindres sur 16065 * 512 octets

Périphérique Amorce    Début       Fin    Blocs   Id  Système
/dev/sda1   *         1       522   4192933+   7  HPFS/NTFS
/dev/sda2           523      1106   4690980    5  Etendue
/dev/sda5           523       547    200781   82  Echange Linux

/dev/sda7           739      1005   2144646   83  Linux
/dev/sda8          1006      1106    811251   83  Linux

Disque /dev/hdc : 240 têtes, 63 secteurs, 3953 cylindres
Unités = cylindres sur 15120 * 512 octets

Périphérique Amorce    Début       Fin    Blocs   Id  Système
/dev/hdc1   *         1       542   4097488+   6  FAT16
/dev/hdc2           543      3953  25787160    f  Win95 Etdue (LBA)
/dev/hdc5           543      3953  25787128+   7  HPFS/NTFS

Here is the Grub report

grub> root (hd0,
 Possible partitions are:
   Partition num: 0,  Filesystem type is fat, partition type 0x6
   Partition num: 4,  Filesystem type unknown, partition type 0x7
 
grub> root (hd1,
 Possible partitions are:
   Partition num: 0,  Filesystem type unknown, partition type 0x7
   Partition num: 4,  Filesystem type unknown, partition type 0x82
   Partition num: 5,  Filesystem type is ext2fs, partition type 0x83
   Partition num: 6,  Filesystem type is ext2fs, partition type 0x83
   Partition num: 7,  Filesystem type is ext2fs, partition type 0x83 

As lilo cannot boot from the second disk hd0 (see: Linux+windowsNt mini-HOWTO)
I cannot use neither:
Dos MBR -> Nt
                -> Lilo as c:\bootsect.dos
Nt boot but linux does not (lilo stopped after “LI”).
Nor:
Lilo MBR        -> Nt
                -> Lilo
neither NT nor linux boot, (lilo stopped after “LI”).

When I try to boot NT from grub on disquette, I get:
-> File system type unknown, partition type 0x7
the Nt entry in the menu.lst on the floppy is:

# Entry 2: chainloaded OS.
title   Windows Nt
root    (hd1,0)
makeactive
# Chainload from the first sector
chainloader +1


Obviously as NTFS is unknown for grub I do not tried GRUB on MBR.

It Grub was able to recognize NTS would be GR...eat !!!

Any idea to solve the problem  (repartionning hd1 is not one and I must have NT)

Thanks a lot for your work
