I am using debian-5.0.0(lenny) . I installed windows xp(a hacked version) on a usb stick. this stick works perfectly well and boots off a windows system successfully.
but on linux it is finding problems to do so.
So I finally decided to put a grub entry to boot off the usb HDD.
So here are the short details . Please have a look.
My menu.lst
Code:
title Debian GNU/Linux, kernel 2.6.26-2-686
root (hd0,0)
kernel /vmlinuz-2.6.26-2-686 root=/dev/sda3 ro
initrd /initrd.img-2.6.26-2-686

well so after choosing Windows XP at the grub menu, it prints this to the console
Code:
Booting WINDOWS XP
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
makeactive
chainloader +1
and then halts . apparently not responding at all.
the same usb hdd boots successfully off a windows system but its facing some problem off this.
My bios perfectly supports usb boot as I have installed debian over the usb through netinstall-iso image and unetbootin.
I am using dell-1520 notebook.
If anyone faced a similar situation, Please let me know.

Hello,
I tried that, but I am at the same position.
but I feel too that it wont cause any difference because if you enter the grub shell ( by typing grub ) and you enter the directives one my one like root (hdx,y) , map (hda,b) (hdc,d), chainloader +1 etc etc and then boot. So it takes in all the commands at once and resolves them before booting them. Kind of Two-Pass Assembler.
One further thing to check: when booting, enter the GRUB shell from the menu (by pressing 'e'), and try to verify that the system can see the USB disk. Because a BIOS being able to boot off an USB drive doesn't mean that the bootloader can see it too, or even at the same location as the booted system.

I don't mean the device map, as that is generated with a running system, mapping the devices by whatever way Linux maps them. If you generate it another time, with another external disc connected, it might well be that your Windows disc is suddenly /dev/sdc or hd2. So the interesting part would be what GRUB itself sees it as.
Background: I've had a SATA disc identified as /dev/sda or hd0 with Linux running, but couldn't boot from it as GRUB saw it after an IDE disk at hd1. So none of the entries matched anymore.
This sounds complicated. If thts true, then its probably impossible to figure out what grub sees sdb as. But I feel the most obvious is that the first external disk is detected as sdb and grub sees it most likely as (hd1) afaik. The rest follows as sdc sdd.and so on.

what was /dev/sda mapped to in device.map ? was it hd0 and still grub saw it as hd1?
