endless GRUB loop while booting

[Sir Gawain]

Hi people!

Today i changed my partitions a little bit. i removed a logical 
partition and created a new primary one. so the numbers of the 
partitions in grub werent valid anymore. so i updated, the menu.lst and 
installed grub again. but after that, the only thing grub do is to print 
"GRUB" in an endless loop to the console...

here is my setup:

/boot/grub/device.map:
(fd0)   /dev/fd0
(hd0)   /dev/hda
(hd1)   /dev/sda

/boot/grub/menu.lst
default 0
timeout 10
fallback 1
title  Debian Linux
root (hd1,7)
kernel (hd1,7)/boot/vmlinuz root=/dev/sda8 vga=1
title  Debian Linux Backup
kernel (hd1,7)/boot/vmlinuz.old root=/dev/sda8 vga=1
title  Debian Linux Single
kernel (hd1,7)/boot/vmlinuz root=/dev/sda8 vga=1 single
title Windows 2000
root        (hd1,0)
makeactive
chainloader +1
title MemTest86
kernel (hd1,7)/boot/memtest86.bin

all stages are under /boot/grub

grub> geometry (hd0) /*-- a ide disc --*/
drive 0x80: C/H/S = 4982/255/63, The number of sectors = 80043264, /dev/hda
   Partition num: 4,  Filesystem type is fat, partition type 0xc
   Partition num: 5,  Filesystem type is fat, partition type 0xc
   Partition num: 6,  Filesystem type is fat, partition type 0xb
   Partition num: 7,  Filesystem type unknown, partition type 0x82
/*linux swap*/

grub> geometry (hd1) /*-- a scsi disk --*/
drive 0x81: C/H/S = 1116/255/63, The number of sectors = 17942584, /dev/sda
   Partition num: 0,  Filesystem type unknown, partition type 0x7 /*ntfs*/
   Partition num: 2,  Filesystem type unknown, partition type 0x7
   Partition num: 4,  Filesystem type is fat, partition type 0xb
   Partition num: 5,  Filesystem type is fat, partition type 0xb
   Partition num: 6,  Filesystem type is ext2fs, partition type 0x83
   Partition num: 7,  Filesystem type is ext2fs, partition type 0x83
/*root of my debian-install*/

(hd1,0) is marked as bootable
i installed grub in (hd1) with the commands:

root (hd1,7)
setup (hd1)

there are no errors shown during setup...
grub> setup (hd1)
 Checking if "/boot/grub/stage1" exists... yes
 Checking if "/boot/grub/stage2" exists... yes
 Checking if "/boot/grub/e2fs_stage1_5" exists... yes
 Running "embed /boot/grub/e2fs_stage1_5 (hd1)"...  16 sectors are 
embedded.
succeeded
 Running "install /boot/grub/stage1 d (hd1) (hd1)1+16 p 
(hd1,7)/boot/grub/stage
2 /boot/grub/menu.lst"... succeeded
Done.

i tried with 0.5.96cvs20010530, 0.90-4 from debian and the cvs of
today. in all versions the same problem.
i use debian unstable.

please answer also to me, because i'm not on the list...
