Hi,

Somewhere during the end of the installation there is a question
Continue without installing (yes/no)
This I assume is if I choose 'Yes' then Grub will not be installed and
when i choose 'No' grub will be installed. But when i choose no, the
installer keeps asking the saem question again and again. May be this
question needs to be re-phrased as "Install grub (y/n)" ?

And no error message? Check also the console (Ctrl+Alt+F4), use Alt+F5
to return to the install.

Hi,
yes there seems to be a problem. But you may still say yes and after the
reboot, just enter into the rescue mode by booting from the installation
CD,then after opening a root shell, run update-grub command.It will
configure grub, then you may reboot and will see the grub screen.

The console at F4 does not show error per-say but says that grub is not
installed and pressing yes does the trick and installs it. But I jut
wanted to point out that the question asked and task performed are not in
sync. Either the yes/no must be toggled of their tasks or the question
must be re-phrased.

I think I understand now what you mean, but can't be 100% sure (I'm
looking at the translation files). It would help if you could post a
screenshot and mention if there were any special steps to get there (for
context).

I had a similar problem recently where some package failed to install,
which caused grub to fail as well. Switching to a console and issuing
aptitude install grub did the trick.

I think the original post was about an event that was happening during
a fresh new install of Debian OS. At that point, I doubt if screen
capture feature is up and running. Maybe I'm wrong. Is there a way to
invoke screen capture during install of Debian? (not merely during
install of a package while running aptitude or apt-get under a fully
functioning Debian host system)

I have seen what seems to me is the phenomenon OP is talking
about. Being under the impression that I could not do a screen
capture, I never really complained about it because I could not figure
out a way to offer evidence that it was just an hallucinating user.

What happened to me seemed to be explained by assuming that grub2 was
actually installed in spite of the fact that there was this error
message claiming that it wasn't. What DIDN'T get installed was any
lines in /boot/grub/grug.cfg that mentioned other OSes that were
already present on the computer. So on reboot, there was only the new
install mention as an option. This is scary, because the new system
might not actually work, but if it does, running grub-install under
the new system brings into play a better version of grub.cfg that does
have lines for the other OSes on the computer. When I discovered this,
I stopped worrying that I was not helping squash a bug. But what I
saw, really was pretty bad, at least cosmetically, since it will be a
part of the first experience of Debian by every future new user.

And then again, maybe I'm wrong, and it really is a recurring
hallucination.

Additionally, maybe significant: All my work was done using
the businesscard CD, squeeze version, which seems to have been
unchanged for a very long time.

I had a different problem, not sure it should have been.

Installed Debian from 5.06 netinst using ssh.

Setup RAID6 over 6 drives (single partition on each drive), lvm2 of that
and there was no way I could install grub [lilo failed, but I didn't
want lilo anyway].

Dropped back to allocating 2 partitions per drive and using the smaller
one as a 6 way RAID1 mirror for /boot -- then RAID6 for the large
partitions with lvm2 covering root and other areas; then I could install
grub.

Cheers

"/boot" can only be on raid1 because the bootloaders need to access
before mdadm assembles the array and, with raid1, the bootloaders can
access one of the submirrors.

I had that several times recently. The sequence of (2?) questions was
messed up. It actually installed Grub even though the questions implied
Grub would not be installed.

I thought Grub2 was going to be able to handle (at least) RAID 5. In theory,
grub2 should be able to support all raid layouts that mdadm does, but it would
require someone porting the relevant code from kernel-space to bootloader-
space.

In the graphical installer the "Screenshot" button is available from the
beginning. I'm now running an installation in VirtualBox to find that
message, but it will be a while...

I can't reproduce this in a VirtualBox install.

Can you please give more details, like what image you used and
preferably the exact and complete text of the message? If you do a
graphical install you can even make screenshots, which you can post
somewhere on the web for us to see.

That's what I thought last December and I tried with raid5 but
couldn't get it to work.

You've now motivated me to try again...

GRUB2 doesn't know what the heck is going on. It goes BACK a step going
"Cool I should install GRUB!"... Previous step says "I've been here" and
we get a loop.

Sorry, I mispoke. I must have made some mistake/mistakes last December
or grub2 wasn't up to the task yet.

I've tried installing Squeeze in a VBox with one partition (just "/"
and no swap) with 3-disk raid5, 4-disk raid6, and 6-disk raid6.

The 6-disk failed; I was dumped to the grub rescue prompt and couldn't
go further because I could only list the raid device and four of the
six disks with "ls"... I have no idea whether it is a VBox limitation
or a grub one; I think that it must be VBox but it's just a more or
less educated guess.

The other two booted up OK.

Going back to the OP, are you using partitioned arrays? (If, yes, FYI
I've tried twice to install grub2 on that type of device and failed;
it could be a PEBKAC though...).

Once the GUI is up, down-left on every screen is a big button that says
"Screenshot" ;)
