John and others,

My configuration is different from yours but similar.
I have a 3 hard disk system
One drive is 60% for backup, 40% for Fedora
One drive 190gigs is split with Windows 7 and Windows XP
The third drive was for Debian.

Here is a nasty.  All drives are SATA.
With a debian boot dvd, the drives appear in one sequence (sda, sdb, sdc for the 3 hard disks)
With Fedora boot dvd, the drives appear in another sequence (sda, sdb, sdc, but different hard disks than for Debian).
All the installers are short on words about what they mean or want to do.

Today I have to rebuild the XP and W7 drive, since sda changed.  
One installer uses the physical hard drive sequence as plugged into the mother board.
One installer uses the logical sequence as I chose for the order that I wanted.

There is an excellent gui program called gparted.  It shows you the partitions and what you have.
It would be wonderful, if that kind of gui representation for the installer was a clickable gui,
to allow me to specify where I want the "lvm partition", where I want the "boot to be installed" and where I want the
swap partition to be installed, or shared. (I do not run Fedora if I run Debian).

Then as you, Debian has grub, its installed clobbered Windows, and I have the similar problem
Grub2 should know and be able to convert grub configuration files.

Debian Squeeze is not for software developers.  Last night, I dropped it completely and
installed Mint 12.  I have the 4 desktops, grub2, and I hope today, with some tweaking
to have it and Fedora in a common boot menu.  Again, I fear that we may be facing
different grub2 versions. (yes, there are differences and some keywords are not recognized in one
that are in the other).

I develop software and need multiple versions, without the VM concept.



Mr. Leslie Satenstein
50 years in IT and going strong.
Yesterday was a good day, today is a better day,
and tomorrow will be even better.

@Debian:~$ dpkg -l | grep grub
ii  grub                                 0.97-64                           GRand Unified Bootloader (dummy package)
ii  grub-common                          1.98+20100804-14+squeeze1         GRand Unified Bootloader, version 2 (common files)
ii  grub-pc                              1.98+20100804-14+squeeze1         GRand Unified Bootloader, version 2 (PC/BIOS version)
Grub2 is apparently installed.  I intend to apt-get purge grub-common and grub-pc and then apt-get install the
packages again.  Unless someone tells me not to do this.
I understand that the installation scripts should then give me the option to chainload grub2.
I am somewhat concerned that grub is now a dummy package.  Is it possible that if I purge grub I will not be
able to reboot?

dist-upgraded - sounds more or less like it didn't install the new grub and grub config at all. You might try loading the system in rescue mode and doing the install the packages manually.

I think the chain loading might have been referring to noticing the NTFS partition and wanting to know if you wanted to include "chain loading" to windows.

These are all assumptions I an in no way a expert. Sounds interesting though. I'd like to read the solution.

Does the location of the grub.cfg and grub files change from being stored in the /boot/grub directory between grub and grub 1.99?

I have a dual boot computer with Vista on one disk and Debian on the other.
I recently dist-upgraded from Lenny to Squeeze. The configuration
script asked if I wanted to chainload grub and I chose not to chainload.
Now I see that it was a mistake to choose not to chainload because
legacy grub only has the older kernels in the menu and now the system
is not really working properly.
So how do I set up the system as if I chose to chainload when I dist-upgraded to Squeeze?
