I am having problems with grub on my pendrive....

Installed DSL (USB-HDD) no problem, under qemu works great ..

Now with bios set to boot USB-HDD (first device)

I get Grub error 15 ???

Wondering ifgrub on my main drive (hda) would affect it ...?

Wiped pendrive & tried to reinstall grub but no go...

My old machine had no problems booting usb, this is first time I have tried on machine just wondering if I need to enable usb-keyboard... if so why?

/me keeps looking for the answer .....

Hmmm. You are right that grub should be on the first boot drive, unless your BIOS is a little screwy and looks first for the MBR on the other drive anyway.

I thought pendrive was wiped clean, that meant it could not boot (unless!!!!)

Could be my grub install on (hda) is out ??

The first line in GRUB should be
default=0
that defines what OS grub boots first (the first one in the list)

What does your menu.lst file for GRUB look like?

You can define boot drives with the GRUB utility like this:

# grub
grub> root (hd0,1)
grub> setup (hd0)
grub> quit

Hi,

I have grub installed on my main system (hda)

Wiped pendrive because of grub error....

Now with USB-HDD set to boot first system locks at grub error 15

If I remove pendrive restart machine system boots fine ...

Now I'm thinking that something on pendrive is preventing system from booting ....

output from cfdisk

Code Sample
                                cfdisk 2.12q

                             Disk Drive: /dev/sda
                        Size: 261881856 bytes, 261 MB
              Heads: 9   Sectors per Track: 56   Cylinders: 1014

   Name        Flags      Part Type  FS Type          [Label]        Size (MB)
------------------------------------------------------------------------------
   sda1        Boot        Primary   Linux ext3       [Pendrive]        261.67



I'm thinking that maybe setting sda1 as bootable is a bad idea ...

I need a way to wipe all pendrove clean any ideas??
