Public bug reported:
Binary package hint: grub2
I have a SATA drive with the following partitions:
sda1 - (hd0,1) - ext4 with /boot from Ubuntu 9.10 Beta
sda2 - (hd0,2) - encrypted (Luks) LVM with swap, / and /home (both ext4)
sda3 - (hd0,3) - NTFS with Windows 7 Professional
Grub2 is installed in the MBR.
The Windows 7 bootloader is installed in sda3.
/boot/grub/grub.cfg is attached.
---
Ok, so Windows 7 can't be started from GRUB.
If I start the automatically added entry:
--->
menuentry "Windows 7 (loader) (on /dev/sda3)" {
insmod ntfs
set root=(hd0,3)
search --no-floppy --fs-uuid --set aeccf515ccf4d893
chainloader +1
}
<---
then grub displays: "error: no such device aeccf515ccf4d893" (triggered by the
search line)
and i can get back into the menu.
If I start my custom entry:
--->
menuentry "Windows 7 Professional" {
insmod ntfs
set root=(hd0,3)
chainloader +1
}
<---
then grub says: "error: out of disk" (triggered by the chainloader line)
Here I can also get back to the menu. So this should be errors from grub and
not from the Win7 bootloader.
Grub gives me a "Filesystem is unknown" if I type "root (hd0,3)" in the command
line at boot.
For "ls -l" I get: (don't know the exact wording as I can't reboot now)
--->
Device hd0: Partition table
Partition hd0,1: Filesystem type ext2, UUID
24ce5eb7-90b3-4051-a0b0-93a280060964
Partition hd0,2: Unknown filesystem
Partition hd0,3: Unknown filesystem
<---
Btw, the module NTFS is loaded (It is listed by lsmod).
I don't really care why there is "ext2" in the first line. Ubuntu boots. No
problem with that.
Second line is expected, because it's en encrypted partition.
But why isn't hd0,3 recognized as ntfs?
The same command in "grub-emu" running in Ubuntu:
--->
sh:grub> ls -l
Device host: Filesystem type hostfs
Device hd0: Partition table
Partition hd0,3: Filesystem type ntfs, UUID aeccf515ccf4d893
Partition hd0,2: Unknown filesystem
Partition hd0,1: Filesystem type ext2, Last modification time

I've found a bug in the Grub bugtracker that could be related to this one:
http://savannah.gnu.org/bugs/?27069
No comments on that report yet.
http://savannah.gnu.org/bugs/?8252 could also be related. I'm not sure.
I'm posting this bug here (and not in the Grub bugtracker), because this
way the chances that this bug gets fixed before 9.10 ships are better.
