Hey everybody,

I just installed Win Xp pro 64 on my new machine and then wanted to install Ubuntu 9.04 64 bit in dual boot - as I have done so many times before with win xp home 32 and Ubuntu - but this time after the install was complete and grub was about to be installed I got the error that grub could not be installed to hd0.

When I installed Ubuntu I chose manual install - as I use to do - to make a ext3 partition (located first on the free space) mounted at / and a swap partition (located last on the free space).

I have searched these forums and the net and tried various guides e.g. this (http://ubuntuforums.org/archive/index.php/t-24113.html) and this (http://ubuntuforums.org/showthread.php?t=224351) but with no luck :(.

Anybody have some ideas? Is because I installed win xp pro 64 instead of the usual win xp home 32, or what? I don not get it :(

Why not install 9.04 64-bit?

As grub is not installed I am not able to boot Ubuntu so I cannot do what you ask. But when booting the live cd I can perform the first command which gives


ubuntu@ubuntu:~$ sudo fdisk -l

Disk /dev/sda: 1500.3 GB, 1500301910016 bytes
255 heads, 63 sectors/track, 182401 cylinders

/dev/sda6 176385 182401 48331521 83 Linux
ubuntu@ubuntu:~$


the second command cannot be run from the live cd.

As you can see my layout is

You should be able to mount your ubuntu partition by clicking on it in nautilus.

If so, then you can try to install grub:


sudo grub
root (hd0,5)
setup (hd0)
quit

and restart to see if the menu comes up.

Ahh, ok. I can see that the file does not exist :(, that is I mounted /media/disk (my ubuntu partition), and here /media/disk/boot/grub/menu.lst does not exist :(

ok, this goes wrong here

sudo grub
root (hd0,5)

I get


ubuntu@ubuntu:~$ sudo grub
Probing devices to guess BIOS drives. This may take a long time.

[ Minimal BASH-like line editing is supported. For
the first word, TAB lists possible command

completions of a device/filename. ]
grub> root (hd0,5)
root (hd0,5)

Error 18: Selected cylinder exceeds maximum supported by BIOS
grub>

I do not get this last part, I can see the whole disk in my BIOS and in windows, so that error 18 is a little misleading.

Scroll down about 3/4.

I have a Asus M4N82 Deluxe motherboard, and it should should support 1.5 TB disks (I can see it correctly in the BIOS and in windows), don't you agree?

As I can see from you link (http://members.iinet.net.au/~herman546/p15.html) I should make a special boot partition with mount-point /boot right? But it appears to me that the error only occurs with legacy hardware, and I have just bought this system :S, or what?

I wil give it a try, using the Super Grub Disk mentioned in you link.

In theory, it should work fine. But since it is not, it might not hurt to try the separate /boot partition.

You also might try mounting your ubuntu partition again, and trying:


sudo grub-install --root-directory=/media/disk Another option is to try supergrub:
