GRUB is not booting the correct partition in a dual drives system
 
I have a system with two hard drives.
On the first hard drive I have windows as the first partition, ubuntu on the second. On the second drive (which is sata) I have a windows partition. After installing ubuntu It would boot the windows partition on the second hard drive not the first. I could get windows to boot on the second drive by using (hd1,0) to try and get windows running on the first drive I have tried (hd0,0) and that does not work. (hd0,1) boots into linux. and linux recognizes the windows partition I want to boot as hda5.

The only solution I can think of at this time are either restoring the windows MBR (which I really don't want to do), or reload ubuntu which would mean I have wasted alot of time setting it up .

Any help would be appreciated,


oh, here is my menu.lst

Remove the two 'map' lines from your Windows entry and add another matching Windows entry (XP on hda5) except instead of hd(0,0) -- which is your first drive -- use hd(1,0). The map entries are sort of redirecting your grub to the other drive. That should do it. However, if the first drive has Windows on the 5th partition, hda5, you will need to use hd(0,4) instead of hd(0,0).

Since your XP Pro on the SATA boots, why not just add the other Windows system to that one's boot.ini file? You'd have to let GRUB boot the SATA system, but that would just show you the Windows boot menu, and you could select the other XP system from there.

You say you've tried (hd0,0). Did your enry look like this:
Code:

title Microsoft Windows XP Professional on hd0,0
rootnoverify (hd0,0)
chainloader +1

If not, try it. It might work . . .

<edit>
Per Mr. Vega's entry, you may need {hd0,4) in the above snippet if your hd0 has xp in partition 5.

Vincent_Vega 01-11-2007 08:28 AM

Yes, that suggestion should definitely work. You could have one XP entry in grub which would direct you to, instead of XP itself, just the Windows boot menu and from there you could select which XP installation you wanted to load.
Either one will do the job.

Thank you Mr.Vega and Mr.Trenholme. I am getting rid of xp on the second drive anyways, and I kinda like grub. I wish it looked a little nicer, maybe a frontend? I have tried hd0,4 but without the rootnoverify, I will see tonight.

Thanks again
