Backtrack 5, Persistence, Grub

[CrazZziK]

Hello everyone,

This is not your regular DUAL BOOT thread.

I've got a netbook that has Win 7 as main system and only 32 gigs of NAND storage. This is why keeping linux on different media is a better solution for me. I've also installed Backtrack 5 r2 on an 8 gig class 10 sd card, works fairly well.

My booting process looks like this:
POST -> GRUB menu on SD card -> Persistence mode Backtrack.

What I need (I would like Win 7 to load by default):
POST -> GRUB menu on SD card -> Windows 7 (boot from first HDD)

Technically, all I need to do is to change GRUB_DEFAULT to X (7 in my case) and run "sudo update-grub" but I get an error message:

/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).

SD card created with unetbootin.

sudo mount
aufs on / type aufs (rw)

Looking for any advice

some advice:
- Kali Linux has replaced BackTrack
- try posting the whole config file, or at least the windows menuentry section, and possibly more details
- isn't better removing the sd card to boot directly in windows? The card probably have no use under windows and being not connected can make it live longer perhaps.
- maybe it's unetbootin fault. I remember that some years ago a writable device with ubuntu live on it (using ubuntu tool and not unetbootin) can save user data. Being backtrack based on ubuntu, have it the same behavior?

Will check it out.

Not in my case.

I've tried LILI. That one is even worse because it does not handle rebooting at all.
