Grub2 in usb stick

Hi!
I installed GRUB2 on a usb stick with:

Code:

---

sudo grub-install --boot-directory=/mnt/lfs/boot /dev/sdb

---

down here you can see how is the usb mounted:

Code:

---

/dev/sdb1 on /mnt/lfs type ext2 (rw)

---

The installation process finished successfully.
Then I edited grub.cfg in /mnt/lfs/boot/grub to the following:

Code:

---

set default=0
set timeout=5

insmod ext2
set root=(hd1,1)

menuentry "LFS test" {
 linux /boot/vmlinuz root=/dev/sdb1 ro
}

---

When I restart the system booting from usb it results in a blank screen with the cursor blinking after 4-5 empty lines. Any idea why it's not showing the boot menu?

Try replacing root entries from sdb to sda in grub.cfg

Code:

---

set root=(hd0,1)

linux /boot/vmlinuz root=dev/sda1 ro

---

I'm trying it right now. The strange thing is that if I enter the grub shell and try to set the root in linux /boot/vmlinuz root=...
it doesnt recognize any sd... device?!

no results

If I enter the grub shell my usb stick is recognized as (hd1,gpt1) (?), which is quite new naming for me.

Post the partition structure of stick. Why do you want to manually install GRUB2 in stick. There are a lot of packages available for GRUB install.

I switched to a HDD partition for now. I created a partition in my HDD (/dev/sda3) and trying to boot the system from there. In the grub shell I write

Code:

---

set default=0
set timeout=5
insmod ext2
set root=(hd0, msdos3)
linux        /boot/vmlinuz root=/dev ro
boot

---

The strange things is that in root=/ if I press <tab> it gives me as possibilities only dev and console! Where are the other partitions?
It start decompressing the kernel and it stops after a while with a Kernel panic fatal exception!
