Ok. So you need a partition table indeed (and give (hd0,0) as root to
grub). Please also give root=device:hd0s1 as parameter to gnumach...

No, because this partition table will live within hda10 only.

Creating a partition table at the beginning of a table never destroys
data, because filesystems like ext2 reserve the beginning of the
partition just for this.
Something that might be important too: in expert mode in fdisk, your
partition should look like
Nr AF Hd Sec Cyl Hd Sec Cyl Start Size ID
1 00 0 1 0 254 63 242 0 3919792 83
Note that Hd is 0, not 1. You may need to type your partition geometry
