I started Grub 1.99-4 from a live cd (grml 2011.05, 64-bit PC) to boot
Windows from disk. Booting Windows failed, no partition was found.
Partitions as listed by sfdisk:

I tried some commands in command mode:
ls listed two devices: (cd) (hd0)
No partition was listed.
ls (cd) listed the top level directory
ls (hd0,1) - error: no such partition.
Same result for the other partitions.
Repeated after insmod ntfs, insmod ext2 - same results as before.
hdparm -i (hd0) - error: ATA pass through not available
Same after insmod biosdisk
probe -p (hd0) - none
probe -d (hd0) - biosdisk
probe (hd0,1) - error: couldn't open device
grub-legacy found all partitions.
Under grml-linux grub-probe identified the partition without problems.
The table list the output of grub-probe /dev/sdan for different targets
(fs, fs_label, fs_uuid, device, partype):
/dev/sda1 : ntfs 74D05028D04FEF44 (hd0,msdos1) msdos
/dev/sda3 : grub-probe: error: cannot find a GRUB drive for /dev/sda3.
Check your device.map.
/dev/sda4 : ext2 bootundlfs dd3379c0-aefe-4381-b6ad-26e5e3934db3

/dev/sda5 : grub-probe: error: unknown filesystem.

Result of grub-mkdevicemap:

Finally the MBR and the partition boot records in raw format
as displayed by cfdisk -r (Windows7 MBR):
