I have googled a lot for this problem.
I found this,
but it didn't solve my problem.
Other solutions suggest me to reinstall grub (run grub-install), which didn't help neither.

Here is what I am doing: (my grub version is 2.02)

1. I use grub2-mkrescue to make my X.iso


2. I boot a VMWareWorkstation virtual machine, which has a 1.0GB SATA disk, from X.iso


3. I install X.iso on disk, the details are:

3.1. erase /dev/sda in case there are old partitions on it:
dd if=/dev/zero of=/dev/sda bs=1M count=1
3.2. Create 3 primary partitions on /dev/sda as dev/sda1,sda2,sda3 (the size is 100M, 30M and 70M),
and toggle sda1 to be bootable

Disk /dev/sda: 1024 MB, 1073741824 bytes, 2097152 sectors

130 cylinders, 255 heads, 63 sectors/track

Units: sectors of 1 * 512 = 512 bytes



Device  Boot StartCHS    EndCHS        StartLBA     EndLBA    Sectors  Size Id Type

/dev/sda1 *  0,1,1       12,191,50           63     204862     204800  100M 83 Linux

/dev/sda2    12,191,51   16,147,2        204863     266302      61440 30.0M 83 Linux

/dev/sda3    16,147,3    25,127,37       266303     409662     143360 70.0M 83 Linux

3.3. Format the 3 partitions as ext2, and mount /dev/sda1

mkfs.ext2 /dev/sda1

mkfs.ext2 /dev/sda2

mkfs.ext2 /dev/sda3

ROOTFS_PATH=/var/.rootfs

mkdir $ROOTFS_PATH

mount /dev/sda1 $ROOTFS_PATH

3.4 copy files...

for i in bzImage initrd.img vmlinuz-*; do

    cp -rf /boot/$i $ROOTFS_PATH/boot

done

cp -f /boot/grub/device.map $ROOTFS_PATH/boot/grub/device.map

for i in init linuxrc; do

    cp -rf /$i $ROOTFS_PATH

done

for i in bin etc lib sbin share usr; do

    cp -a /$i $ROOTFS_PATH

done

for i in dev var proc sys tmp data log; do

    mkdir -p $ROOTFS_PATH/$i

done

3.5 Install grub and make grub config file

chroot $ROOTFS_PATH <<EOF

mount -a

mdev -s

grub-install $tdisk

grub-install --recheck $tdisk

grub-mkconfig -o /boot/grub/grub.cfg

exit

EOF

4. reboot

It says:

.

error: disk 'hd0,msdos1' not found

Entering rescue mode...

grub rescue>

And the most strange thing is that ls command shows nothing in grub-rescue cli
---- as someone says, it should show disk list.

Could anyone help me to get over this? Any suggestion may be help.
