Dual boot with XP 64-bit Problem [Solved]

[godv2]

Hey guys,

a few days ago i downloaded Sabayon 4.1, the KDE one, and i've been very impressed with it so far

anyways, i tried to boot back into windows (XP 64-bit) for the first time since, and a problem came up:

i selected it at the GRUB menu, and it gave the following message:

root (hd1,0)
filesystem type unknown partition type 0x7
chainloader +1
savedefault


then it sits at that screen and doesn't respond to anything until i reboot and it does it again.

I have 2 hard drives, Windows and Sabayon are both on the first and the second is for storage.

any ideas how to get back into windows?

Cheers, TJ

The grub convention for drives and partitions is as follows:

(hd<d>,<p>)

Drive
sda => make <d> 0
sdb => make <d> 1
sdc => make <d> 2
etc.

Partition
1 => make <p> 0
2 => make <p> 1
3 => make <p> 2
etc.

Thus e.g. /dev/sda5 would be (hd0,4)

To configure grub, run it as root in a Terminal window:

a) If you have, or want, grub installed in the MBR then do the following:

# grub
grub> root (hd0,2) <-- specify partition where grub is to reside (sda3 in this example)
grub> setup (hd0,0) <-- install grub in MBR (sda1 in this example)
grub> quit


b) If you have, or want, grub installed in a Linux partition rather than the MBR then do the following:

# grub
grub> root (hd0,2) <-- specify where partition containing /boot resides (sda3 in this example)
grub> setup (hd0,2) <-- install grub in /boot (sda3 in this example)
grub> quit

My /boot/grub/grub.conf file corresponding the (b) above looks like this:

Code: Select all

# grub.conf generated by the Sabayon Linux Installer
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,2)
#          kernel /kernel-genkernel real_root=/dev/sda6
#          initrd /initramfs-genkernel
#boot=sda3
default=0
timeout=10
splashimage=(hd0,2)/grub/splash.xpm.gz
password --md5 $1$s0K6ZclI$MTvmWuyvIPrzYz2npKAix/

        rootnoverify (hd0,1)
        chainloader +1

Notice that the rootnoverify command for the Grub Windows XP menu entry is hd0,1 = sda2, i.e. my Windows XP partition to boot is sda2, which happens to be my Windows XP C: drive.

Maybe you just need to boot a LiveDVD/CD and edit your /boot/grub/grub.conf to point to the correct partition.

Thanks!

I changed it to (hd0,0) and it worked straight away
