Default Lousy Lynx

I have a couple of systems that run Ubuntu part-time. *Both dual-boot with Vista because I put them in on Dell machines and had plenty of disk space.To do this, I did a couple of odd things to the partition table. *I took space away from Vista, and added a swap and Linux (sda6 and sda7). This leaves
the partitions out of order, but makes it possible to talk to Dell tech support and not have to mention their presence (there's a weird partition at the end of thedrive whose purpose I don't know, and I did not want to fiddle with it.

I teach computer science in university, and I'm about to be humbled. *Classes start tomorrow, and my laptop Ubuntu is hosed. *It decided yesterday thatit no longer knew anything about its LAN or wireless cards. *I could not figure out the config tools which seemed to need the MAC address (I know what it
means, but I don't know how to find that number on a broken system where 'ifconfig' isn't seeing them). *This makes it hard to work with.
Fortunately, I can boot from floppy. *I expect the Vista system is okay, because it was okay until I changed the Linux paritions' locations because I want
to give a little space back to Vista. * But now grub is hosed, sort of. *The good news is I have a portable 2TB drive with both SATA and USB, so I've beengetting things to the laptop by "sneakernet", and it's pretty quick. *But overall, the machine is useless at the moment.

I've booted from CD, restored a backup, and chrooted to my root partition where things seem okay. *I've run grub-install * * grub-install --root-partition=/mnt/root /dev/sda
and my menu.lst looks okay. *Problem is that on reboot, I just get the grub shell and I don't know how to use it. *If I could get to the menu, I'd probably beokay.**I'd even be workable for class tomorrow if I could just boot the vista partition, but I'm not sure how to restore the MS MBR, and I don't think I backed that up.

Final problem: neither the desktop nor the alternative 10.04.1 CD is willing to install on my sda, doubtless because of the funny partition arrangement. *The partition utility sees SDA, but disavows any knowledge of any partitions on it. *My command-line tools work okay, and fdisk does report that partitions are out of order,

but does not otherwise seem to mind.
I'm okay with this eventually, because I know I can install and older Ubuntu on it (I did it once, somehow), and take the upgrade route (I had held off until summer, but didn't get around to it until a couple of weeks ago, so I know this can be done). *I think I have had 8.04 on it, and am sure I had 9.04 and 9.10. *I'm pretty sure I had to use alternate install, but it worked.

Anybody with a quick idea or two? At the moment, I desperately need Vista because it's got my Dreamweaver CS4 on it (which does not virtualize well). *
HELP!

Just to get to Vista (for now) and from your message, I assume it is on
grub-legacy; at grub prompt,
root (hd0,x)
chainload +1
boot

where (hd0,x) is /dev/sda(x+1)
so if Vista is at sda1, it should be (hd0,0).

If it is in fact grub2, see my previous post to Colin.

It seems so completely unlikely that you don't know how to restore a
Microsoft Master Boot Record /and/ aren't able to lay your hands on the
info in seconds that I have trouble believing your first statement.

If true, I pity the youth of today.

From the /very first result/ of a googling for, "restore vista mbr":
http://forums.techarena.in/vista-help/691963.htm

----------
How to Repair or Fix a broken Vista MBR:

To Restore Vista MBR, please use the following simple solution.

1. Start your computer from the Windows Vista Installation DVD
2. Press a key when prompted to continue
3. Choose your language, time, keyboard and click Next:

Select language and preferences
4. Next, click "Repair your Computer":

Repair your computer
5. Now, from the System Recovery Options dialog, select the "Operating
System" you want to repair, then click Next:

System recovery options, choosing your Operating system
6. From the "Choose a Recovery Tool" dialog menu, select "Command
Prompt":

Recovery Tool Command Prompt
7. Type the following into the "Command Prompt Window":

bootrec.exe /fixmbr
bootrec.exe /fixboot

8. Remove the Vista Installation DVD and restart your PC.

If all goes well, this process should have enabled you to restore your
Vista MBR and you should now be able to boot back into your Windows
Vista Operating system.
---------

As I have no MS anything, I HTH, but YMMV.

Cybe, relational databases, not operating systems. My doctor don't know
a thing about fuel pumps and my mechanic don't know a thing about
incisors. But doctors, mechanics and dentists make more money than you
or I (okay, me) because we are generalists and they specialize.

I used to be a specialist in the metabolic crystalline combinatorics of
the endocrine secretions of salivary glands of the mongolian tsetze fly
but there was no market for my expertise. And I don't know a thing
about locusts.

So be nice to specialists. They may be unemployed one day. Like when
databases use discrete hexadecamicals instead.

Take care, and without malice - Goh Lip

agreed. sounds much more like someone on an ego boosting trip that hasnt

doesnt get much simpler than booting your windows install disc, choosing
your install, and typing fixmbr. I think i taught my 17 yr old son that
about 10 years ago. thank (insert your favorite higher power of choice lol)

I've been monitoring the list for a week or so, thinking of converting
to Ubuntu. I was impressed by the quality and helpfulness of the list,
and the lack of personal attacks. But, it seems that there are folks
here who get their kicks by ranting on and on about how someone else
is a complete idiot for asking what that knows-everything person has
deemed a silly question. Too bad - it diminishes the quality of the
list, especially for beginners.

Since you knew the answer, it would have been much better, and MUCH
nicer, to have simply responded with JUST the answer. Saved you some
typing, too. :-) Would have kept up the list quality, and left a much
better impression of you as well...

there's also the SuperGrub disk that does a good job, at least the few
times I've used it. The OP seemed more interested in getting into
Vista by re-enabling the MBR of Winduhs, though.

Interesting, will this RedoMBR bring back or set back the original grub
and set that to mbr (sda)? Even if the grub is from Ubuntu and there is
no PCLinux on the hard drive?

Anyway, to set back the original grub from Cybe's method, booting up
Ubuntu livecd and then
sudo grub-install --root-directory=/path_to_Ubuntu/partition /dev/sda
Or simply use a grub-rescue cd that you made beforehand.
Or a more complicated chroot from the livecd as mentioned in Ubuntu's
documentation.

Assuming all that works, you now have to get back your Linux system(s).
On the live version of the PCLINUXOS CD, when you get into the
GUI, there's More Applications>Configuration>RedoMBR.
When it asks, tell it OK. Hopefully this will bring back your Linux(s),
assuming they booted from grub in the first place.
