Locked out of vista! (can you change config from outside OS?)

I must have deleted my entry for Vista when I was mucking around with a fresh easyBCD install. I installed neoGRUB, but before I had a chance to configure it, I logged out to boot into Mandriva (to copy my menu.lst configurations), so now when I log back in, it's at a GRUB prompt (since I never changed the config) and I can't boot into Vista at all! :S

Is there a way to change configurations or settings from outside the OS?

Or is there a command from the neoGRUB prompt that will let me boot Vista? (at hd0,1)

I only need to get back in once, but when I try to set root/kernel/chainloader, it just boots back to the same GRUB prompt.

I've even restored a Vista bootloader from UBCD4Win, but it's just back to the GRUB prompt.

Please help! Is there anything I can do? :scared:

Addendum:

Update: so I managed, with the help of ntfs-3g to find and edit the menu.lst file in C:\NST, but I'm having trouble making setting it up to boot Vista.

I tried copying and pasting /boot/grub/menu.lst, and that will let me load mandriva, but no Vista.

Code:

color black/cyan yellow/cyan
gfxmenu (hd0,4)/boot/gfxmenu
default 0

title Mandriva
kernel (hd0,4)/boot/vmlinuz BOOT_IMAGE=1337 root=/dev/sda5 resume=/dev/sda6 splash=verbose vga=791
initrd (hd0,4)/boot/initrd.img

title Vista
root (hd0,0)
makeactive
chainloader +1

title BT2
root (hd0,10)
kernel /boot/vmlinuz rw root=/dev/sda11

What do I need to do in menu.lst to start Vista (located on the first partition of the drive)?

 

Wouldn't restoring a Vista bootloader with UBCD4Win pretty much be doing the same thing?

I overwrote the graphical GRUB bootloader that's native to my Mandriva install, and rewrote a Vista MBR with it (UBCD), but since it's been altered by easyBCD, it's just loading an unconfigured neoGRUB...again.

Well actually since I found I can edit NST/menu.lst, I can use it to boot into Mandriva and BT2, but when I try to load Vista I get told to run fdisk, and after a few errors it winds up going back to the neoGRUB selection.

I'll reload the Vista MBR with the .iso you provided, but what I really need is help configuring NST/menu.lst to make it boot Vista, I can fix it if I can get into it even once and run the easyBCD GUI.

 

Done and back in Vista. :happy:

Vista was constantly overwriting GRUB when I'd run certain apps (without fail every time I ran a CS3 app...it was the strangest thing), and I was consistently having to whip out my superGRUB disc. It will be great if this stands up to Vista's wacky MBR overwriting.

Now if only I could figure out a way to give neoGRUB a graphic background like GRUB had..is that even possible?

ps: thanks a ton for the support and quick help! I can think of quite a few companies that could stand to take a que from you guys in service.

 

Uh oh. :scared::x:scared:

I fixed deletion of the Vista entry with the iso provided, but since I have neoGRUB as default with time of "0", I basically locked myself out of vista again!

Is there a text config file for easyBCD that I can change the default load time on from outside of Vista, or is there a key I can press that will stop neoGRUB from loading??

....again, I just need to get into Vista once, to undo my mistake, and I'll be ok.



edit: this time I'll leave it the fsck alone, I swear!
