Re: Newbie question about amd64 Xen Dom0

Hi Manuel and Geert:

I was not successful installing Grub on my real box :(

This is my environment:

I have an amd64 athlon x2 with 4Gb RAM,
my motherboard is an ASUS M2NPV
I have a 230 Gb SATA disk and this is the disk layout:

[I am using the entire disk for NetBSD]:

wd1a /               (32)
wd1b swap        (4Gb)
wd1e /partition2 (40Gb)
wd1f  /partition3 (70Gb)
wd1g /partition4 (80Gb)

I installed NetBSD successfully and followed all steps described in the HOWTO,
anyway, when I try to run

grub-install I get a:

The file /grub/stage1 not read correctly.

and if I try running

grub
--> root (hd0,0,a)
--> setup (hd0)

I get:

grub> setup (hd0)
 Checking if "/boot/grub/stage1" exists... no
 Checking if "/grub/stage1" exists... no

Error 25: Disk read error

As you know, grub has autocompletion when you press the TAB key; I
realized that the autocompletion with /etc [by example] works
perfectly, but with /grub it does not. With /etc/[TAB], the
autocompletion shows all the files inside /etc; but with /grub/[TAB],
an "Error 25: Disk read error" is shown.

/grub/ exists, contains all the *stage* files and is in the same partition to /.

I have also compared the owner, group and permissions on all the
files, and there is no difference with the files stored in /etc.

I do not know how to deal with this problem,

any help will be very useful.

Best regards,


Ernesto
