I got a new laptop a little while ago. It came with vista home premium on it. I really don't like vista(even less than xp) so I figured I would setup a dual boot and if I got everything working correctly I was going to remove windows. This is the first time that I have tried to setup a dual boot with debian. I have done it with ubuntu before but not debain.

 

I must have done something wrong during the initial install that completely fubared my MBR.  I don't have a vista restore cd but I have a really old xp cd. I figured that I could get into the restore console with it but I when I do it asks for an Admin password that I don't know. I am the only user on the system and I *know* what my password is but it keeps telling me that it is incorrect. I tried my password, no password and 123456.. None of which worked. So I decided to try to fix it through grub. Below is the process I used:

 

 

I entered the debian dvd and when I got to the network dialog I hit alt f2 which brings up BusyBox(the built in shell). Then I did fdisk -l to see my partitions.

# fdisk -l

Device       Boot       
/dev/sda1                 
/dev/sda2                
/dev/sda3                
/dev/sda4               
/dev/sda5               
/dev/sda6   *          
/dev/sda7            

 

/dev/sda5 is the root partition, /dev/sda6 is the boot partition and /dev/sda7 is swap.

 

From BusyBox I did

 

mount /dev/sda5 /mnt

chroot /mnt

 

Which dropped me into the root for the debian install. I then loaded grub and tried to setup the MBR like this:

 

grub

grub -> root (hd0,5)

grub -> setup (hd0)

 

That completes without any errors but when I reboot I am still unable to get grub to boot. It just searches for other bootable media. I don't have a cd burner on my other system but I am going to go buy a usb flash drive and try http://www.gnu.org/software/grub/manual/html_node/Making-a-GRUB-bootable-CD-ROM.html . I have really bad connection or I would download a live cd. Well, I downloaded the DSL(damn small linux) iso and will try it if the grub booter doesn't work.

 

At this point I am pretty much lost. I don't want to write over the windows install as I have a few things I still need access to. Any other suggestions would be greatly appreciated.

Um... what? I'm pretty sure you mis-read something.

 

And, Tom, when you say that you "loaded grub", what do you mean? And did you have /boot mounted at the time you were running "root (hd0,5)", "setup (hd0)", etc., in grub? If not, I think that might have something to do with it.

by entering "grub" at the command prompt the grub command shell environment will be loaded.

Yes I did.. I left that out last time. Here is what I did

 

mount /dev/sda5 /mnt

mount /dev/sda6 /mnt/boot

chroot mnt

grub

grub>root (hd0,5)  #/dev/sda6

grub>setup (hd0)

grub>quit

exit

then rebooted.

This what what I was reffering to, he said he tried his password, and it didnt work.  I have vista on a laptop, and there must be somethigngwith it that the admin password is not your password.  I had to use the program to be able to install things, and even search Documents and Settings folder for sessions to work on my laptop for development.

after more searching I found a solution and debian now boots

 

From the BusyBox shell in the debian install(alt f4)

mount /dev/sda5 /mnt

mount /dev/sda6 /mnt/boot

chroot /mnt

grub

grub>root (hd0,5)

grub>setup (hd0)

grub>rootnoverify (hd0,0)

grub>makeactive

grub>chainloader +1

grub>boot

exit

then reboot

 

Now grub boots fine
