hi, �橇�
Thanks a lot for your help :)
You are right, my usb disk is (hd0,1) if I choose boot from USB Hard
Disk in BIOS. If I choose to boot from hard disk, the usb disk is
(hd1,1). The grub.cfg in usb disk has:
set root=(hd0,1)
search --no-floppy --fs-uuid --set 119b5aaf-7d23-45d7-bcb8-b6b94a5eb238
May I ask what env variable root is used for by grub?
I tried these commands in grub command line after booting from usb disk:
grub>echo $root
hd1,8
grub>set root=(hd0,1)
grub>ls /
boot, grub, ...
It shows that after executing command 'set root=(hd0,1)', root
directory '/' is set to disk (hd0,1). But in this disk, I just create
a folder 'boot', why a folder named 'grub' is created here?
As for the grub-mkrescue command, the syntax may be in Grub 1.97beta:
grub-mkrescue grub-rescue.iso :)
NOTE:
commands used to install grub to usb disk:
$ sudo grub-install /dev/sdb1
$ mount /dev/sdb1 /media/usb01
$ cd /media/usb01
$ mkdir -p ./boot/grub
$ cp -dpR /boot/grub/* ./boot/grub
(edit /media/usb01/boot/grub/grub.cfg as mentioned above)
