thing in the grub console but i just runt the grub-install command
instead to install the stuff now thing are fine. now i am stuck in
samba and Microsoft activedirectory 2003 integration issue.
ahhh :( paaain.

Only that information was displayed? I'd would have expected more

Good. And what happens now when you try to boot with only one disk
connected? Or have you tried something to check this?
In brief, what I'm trying to say is... what's the problem by now? :-)

Wait, wait... let's try to clear some points first.
1/ Are you using GRUB legacy or GRUB 2? I already asked you this but you
still have not replied to this question (or I don't remember). It is
important to know what's your GRUB's version as both versions differ a
lot.
2/ "update-grub" is not used to upgrade GRUB legacy to GRUB 2, it's a
routine used to reconciliate/populate the changes you've made in your
menu or configuration files (read "man update-grub" if you need detailed
info on what it does).
3/ Are you running Lenny or Squeeze? Lenny is not supported anymore (no
security patches) so installing lenny -unless you have a specific
requirement for doing so- is a bad move and a waste of time... you should
reconsider getting squeeze instead.
4/ You will have to confront GRUB 2 sooner or later :-)

So you're running Lenny... then sir, I'm sorry to say this but you really
should reconsider reinstalling your full system with squeeze (current
Debian stable) and now that you still have not started to install
packages I'd say is the best time for doing it.

Only that information was displayed? I'd would have expected more
("searching for splash image", "searching for kernel"...), but well, at a
first glance looks right to me, no errors at least.
Just in case, try to run "update-grub" and check if that fixes the
booting issue.

If you're using GRUB2 I can't understand why the those commands did not
complain given that partition "0" shouldn't exist :-?

Thank you every one for helping me. actually i followed and read every thing but just "grub install /dev/sdb" alone didn't help i also run some commands in grub as well grub install /dev/sda (not necessary ) grub install /dev/sdb grub grub> root (hd0,0) grub> setup (hd0) grub> root (hd1,0) grub> setup (hd1) grub> quit Thank Camaleón. your links literally helped me a lot. :) Thanks MYK -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

The debian-installer doesn't install grub onto both raid disks. Arguably it should. But it doesn't. Perhaps in a future version this will be fixed. For Squeeze it doesn't. Hopefully in Wheezy. The debian-installer in Squeeze only installs grub on the first disk. Usually that will be /dev/sda. Meaning that /dev/sda will boot okay. Meaning that the second disk /dev/sdb will *not* boot. This is a known deficiency. To correct this issue follow the instructions posted by Tom in his message. You will need to install grub manually to the second drive as Tom example shows. grub-install /dev/sdb After that it should boot from either drive okay.

Re: RAID1 does not boot
Thanks, i found out the problem but still i am confused actually i have disk 1 and disk 2 with same specs like they both are 320 GB and same made. here is my partition flow (because i had tried installation so many times so i change the partition structure) 1. /Boot 1GB (Boot on and on RAID /dev/md0) 2. SWAP 4 GB (RAID /dev/md1) 3, / (remaining space) (RAID /dev/md2) now at the end after installation when system rebooted for the first time i receive "error loading operating system" actually in BIOS boot option i mistakenly selected SATA2 as boot instead of SATA 1. when i shift things back i manage to reach grub menu. now the part where i am confuse is that i believed that the computer should have booted from SATA2 as well because boot partition is also installed over it too. as i have created /boot partiton on RAID which was md0. now for instance if my SATA 1 goes down then i would be handicap as it will not going to boot from SATA2. please suggest me what should i do in this regard. because what i want that, if some thing happen to any of the drive i just have to unplug the bad one and replace it with the new one ofcourse i know i have to make same RAID partition and stuff but what i want is if SATA1 Fails i want SATA 2 to boot with out any complex efforts.

RAID1 does not boot
Dear All, i am a newbie, i tried RAID 1 installation on VM which was working fine. now i tried to install the same scenario on physical machine. i have two 300 GB Hard drives and i want to make a RAID1 every things work perfectly. i created the RAID partition and then RAID device. i created 3 partition on the RAID drive. 1./boot (1GB) 2.SWAP (not on RAID) 3./Root (300 GB) now everything when fine to the end of the installation but the problem is when i restart the machine after installation. it doest boot however in VM machine it didn't happen. but one thing i notice during installation it is giving me the message "the Kernel was unable to re-read the partition table on /dev/md0 (invalid argument) this means Linux won't know anything about the modifications you made until you reboot you should reboot you computer before doing anyting with /dev/md0. i tried Squeez 6.0.4 and Lenny several times and at the end no-success. kindly Help!
