[SOLVED]the grub doesn't work

hi.. firstly sorry for my english.. ok when I finish the installation of archlinux x86_64 I reboot and then when the grub screen appeared I select achlinux and i get something like "the filesystem cannot be mounted". my question is ¿what is the version of the grub that i installed from the archlinux cd? but I believe that the problem may be the ext4 filesystem.. ¿may I install archlinux in a ext4 filesystem?

thank you and sorry for my english .. I hope you understand me.

Re: [SOLVED]the grub doesn't work

From what you are saying, I surmise that you do not have a seperate /boot filesystem - or if you do - that is also ext4.
Legacy grub does not support ext4 - which a quick search would have told you ...

Re: [SOLVED]the grub doesn't work

You should reinstall archlinux and this time choose another filesystem type for your boot partition , for example ext2

Re: [SOLVED]the grub doesn't work

exactly.. I suposed that.. thank you.. then merely I have to separate BOOT in other partition and put it in ext3.. rather.. I going to partitionate my disk like this:

/=ext4
/home=ext4
/boot=ext3
swap

correct?

Re: [SOLVED]the grub doesn't work

huh? o.o maybe you've done something wrong with partition phase in the installation

I didnt separate /boot partition, whole root directory / is ext4 an its working perfectly, just I must to add /boot to the kernel line in the menu.lst
like this:

kernel /boot/vmlinuz26 root=/dev/sda3 ro vga=773
initrd /boot/kernel26.img 

else if i separate /boot partition, no need to add /boot to menu.lst

i've installed Arch, using lastest iso image (# Current Release: 2010.05 # Included Kernel: 2.6.33.4) and no problems.

Re: [SOLVED]the grub doesn't work

bad news.. the solution in http://wiki.archlinux.org/index.php/Grub#GRUB_Error_17 doesn't work for me..
I've tried format the partition /boot with ext3 and ext2 and others partition with ext4 and ext3 but it doesn't work..

may be the MBR?...

note: i have another HD (hda) with windows 7.. maybe do I have to install grub in hda, mandatory?
thank you!! I hope you understand me!

Re: [SOLVED]the grub doesn't work

Where did you install grub ??
You said you have another hard disk, and you identified it as hda. 

Please verify whether you've one or two disks.

Did the system used to boot Windows 7? Does It still boot?

Is it your intention to dual boot Windows 7 and Arch Linux, installed on different disks from Grub?

Alternately, are you telling your BIOS from which hard disk to boot -- With the Windows boot loader on one and Grub on the other?

Re: [SOLVED]the grub doesn't work

*in hda, i have windows 7 and i'm trying to install arch linux in my new HD (hdb)

*my sistem boot windows 7, but i have to change ther order in the bios or select the disk in the popup menu. but it still boot windows 7
*yes it is
*yes i am but when i install arch linux and try to boot it from the grub i get the message..

Filesystem type unknown,
partition type 0x6
kernel /vmlinuz26 root=/dev/sdb1 ro
Error 17: cannot mount select partition

previously i had windows 7 and archlinux installed in my sistem in diferrent disks, but in that time i (accidentally) installed the grub in the MBR of hda (in the disk that has windows 7)

Re: [SOLVED]the grub doesn't work

If you've changed the order in the BIOS, then the drive identification might have changed. You could try changing

kernel /vmlinuz26 root=/dev/sdb1 ro

to

kernel /vmlinuz26 root=/dev/sda1 ro

Re: [SOLVED]the grub doesn't work

Okay, I think the problem is the order of the drives.  When you change the order in the BIOS, I think the system maps the boot drive to sda.  Mind you, I am not an expert in Grub by any stretch of the imagination.

If you notice, it is complaining that it does not know what I partition type 06 is.  06 is a FAT partition.  I'll bet the other disk has a FAT partition in that partition.

Try changing your command line in grub to refer to sda rather than sdb.   If that does not work, you may need to go in an change your /etc/fstab in your new Arch build.
