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:

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
