Dual boot problem w/ Sabayon
Here's the problem: I have sda, which has Windows XP on it and sdb, which has Sabayon installed on it. I installed GRUB to the MBR on sdb and switched the driver order in the BIOS. I've never had a problem making this work before, but I can't seem to boot to Windows now. Here's the menu.lst that Sabayon generated at installation time:
Code:
# grub.conf generated by anaconda |
title windows
rootnoverify (hdx,x) map (hd1) (hd0) <----------- vital! map (hd0) (hd1) <----------- vital! chainloader +1 |
Tried that... All I get is:
Code:
Booting... 'Windows x86_64' |
OK, then use
title windows rootnoverify (hd1,4) makeactive map (hd0) (hd1) map (hd1) (hd0) chainloader +1 |
Code:
Error 12: Invalid Device. |
That is a weird layout you have. Is your windows really on the fifth partition of the second drive. If so, it shouldn't be too difficult to see why it fails to boot:
- either XP is not on that fifth partition and you need to adjust GRUB to reflect its actual location - or it really is in the fifth partition, which by definition is not a primary but a logical partition - and windows needs to be on a primary partition if it is to boot at all. Solution: move XP to a primary partition. I don't know what happened. Did you edit the root statements for both operating systems? |
For some stupid reason, XP decided to create an extended partition at the beginning of the drive. I don't know what the deal is with that. I've done this before using 'map', but it doesn't want to work now. Perhaps, I will try to (ughhh) reinstall Windows.

hey Y do u want to re-install windows
just change drive order.. & then change GRUB to be in the MBR of hda or sda in ur case.. |
The reason I switched the drive order is because Windows can overwrite the MBR on the drive. I know I could just reinstall GRUB in that case, but I also know that I've made it work with my current configuration before.
|
Are you sure that you left a space between the (hd) parts of the map statemenets? I remember one occasion where I didn't and XP wouldn't boot either. Little things like these are easily overlooked but they can have some nasty consequences.
|
Yeah, I've actually had that problem in the past too, so I don't make that mistake any more.
|
So could this be an issue with the Sabayon bootloader? Have you tried booting windows from a livecd?
|
It worked fine with Gentoo, but I haven't tried with a LiveCD.

Knoppix rescue to avoid reinstall on Windows XP
I had the same problem with Sabayon with the same configuration on the hard drives finally rebooted with Knoppix 5.1.1 which often seems to work as a rescue disc. Let me know if you come up with another solution to mounting the Sabayon.
