[SOLVED] Dual boot and GRUB woes

I want a dual boot system with Arch and Windows running on the same disk. My partition table looks like this:

hda1 = Windows XP, ntfs, 7,7 GB (boot)
hda2 = /, ext3, ~7,2 GB
hda5 = swap, 500 MB
hda6 = /home, ~13 GB

(The drive is only 30 GB in total, it's an old laptop.)

My problem is that after installation, GRUB always fails to load. This last time I reinstalled Windows, reformatted the rest of the partitions, installed Arch, and put GRUB on the / partition (hda2). Result: no GRUB, Windows is loaded directly.

My questions are:

- Would it help to install GRUB on a separate /boot partition?
- Which of the partitions are supposed to be bootable, primary and secondary?
- What if I install GRUB on the MBR instead? Wouldn't that cause the Windows bootloader to fail?
- Am I even asking the right questions? (If not, how would you do this?)

I'm not a complete beginner but I think I need some help here.

Put grub on the MBR and make an entry in the menu.lst for WIndows.  Easy.

Re: [SOLVED] Dual boot and GRUB woes

It worked, thanks! I had tried it before of course but forgotten to uncomment the Windows part in menu.lst. Where's the wallbanger smiley when you need it?

Anyway, now I have another problem, possibly more serious. When I try to boot into Arch, it gives me an error:

FILESYSTEM CHECK FAILED

/dev/hda2 The superblock could not be read.

Then it mounts the disks as read-only and lets me choose between entering a maintenance shell or reboot.

I've tried issuing the command it recommends, "e2fsck -b 8193 /dev/sda2" (as the partition now seems to be called), but it doesn't help. I've also tried "e2fsck -p /dev/sda2" as someone recommended in another thread, but the problem persists.

Any more ideas?

Re: [SOLVED] Dual boot and GRUB woes

Can you post your /etc/fstab?

It looks like this:

#
# /etc/fstab: static file system information
#
# <file system>                     <dir>                 <type>                <options>      <dump>   <pass>
devpts                              /dev/pts               devpts                  defaults      0         0
shm                                 /dev/shm               tmpfs                   nodev,nosuid  0         0

#/dev/fd0                           /media/fl         auto          user,noauto                 0         0

/dev/hda2 / ext3 defaults 0 1
/dev/hda5 swap swap defaults 0 0
/dev/hda6 /home / defaults 0 1

Re: [SOLVED] Dual boot and GRUB woes

Not sure, but a couple things:

1] Have you tried booting a live disk to run the fsck?

2] You could try using UID= instead of /dev/hda in the fstab. I was having a similar problem if my partition booted in the wrong order, which went away when I used UID. The blkd command will tell you the UUID of a drive. Then, instead of /dev/hda2, you would put in UUID=

# blkid
/dev/sdb4: UUID="303889b7-ae78-436f-85ac-da95b2280596" TYPE="ext3"

So it would be:

UUID="303889b7-ae78-436f-85ac-da95b2280596" / ext3 defaults 0 1

Surprisingly, the UUID trick worked. Thank you very much!

I'm doing the rest of the install process now. I'll let you know if I bump into any more problems that I can't solve by myself.

Re: [SOLVED] Dual boot and GRUB woes

Good to hear! You should change the topic to [solved] in that case.

All right! Everything worked out fine in the end. Typing this now from my new Arch Linux setup. Really impressed by the community so far. Thanks a lot!
