Debian on USB HDD GRUB problem

[larret]

Hi guys. I got same problem while a little different configuration with Debian.

# /etc/fstab: static file system information.
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sdb1       /               ext3    defaults,errors=remount-ro 0       1
/dev/sdb6       /home           ext3    defaults        0       2
/dev/sdb5       none            swap    sw              0       0
/dev/hdc        /media/cdrom0   iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0

I got winXp on SATA installed, and now I try to boot Debian from USB-HDD propely.

title		Debian GNU/Linux, kernel 2.4.27-speakup 
root		(hd1,0)
kernel		/boot/vmlinuz-2.4.27-speakup root=/dev/sdb1 ro 
initrd		/boot/initrd.img-2.4.27-speakup
savedefault
boot

title		Microsoft Windows XP Professional
root		(hd0,0)
savedefault
chainloader	+1

What is interesting - it can't boot Debian from usb-hdd sdb(hd1,0), i got to change GRUBs entry to sda(hd0,0) which really is internal SATA with winXp...
i tryed to unmount SATA... still problem isn't solved.

where did you install GRUB? if you select 'boot up from External Drive', BIOS assigns device name sda to external driver.
