How to add entry to GRUB2 with 2 hard disks
 

I am a newbie !
I have two ide hard disks.
One with windows and other with ubuntu 10.04.
i want both windows and ubuntu in grub menu so what should i do ?
thanks in advance!!

1. plug in both hard drives.
2. it would be better if linux boots up, because linux use grub where you can add another OS
3. this another OS - windows is added to grub by selecting boot command and hard drive where os is located

edit as superuser:/boot/grub

my advice:try to sitck to single-OS as newbie as it is easier

http://www.gnu.org/manual/

http://www.gnu.org/software/grub/manual/

Basically it depends. Is grub currently installed? Which OS does it currently boot / not boot? What distro? And other factors.

Technically speaking, the device has to appear in:
/boot/grub/device.map

And an entry for the bootable item in:
/boot/grub/grub.cfg

How you get there from here and how that looks varies. Could be as simple as:
# dpkg-reconfigure grub2

Or something less cordial. If grub / grub2 is not currently installed, it gets even more tricky. More details would helps us help you.

Stay far away from Grub 2!!
 

I'v spent waaaaaay too much time trying to get grub 2 to work.

So I am just waiting until they get a decent version out finally.

Meanwhile, I'd just use the original grub (legacy) ver. 0.97-61

It does everything you want..

If you are using ext4 on any of your bootable partitions.. then you need to have a separate partition for grub files (kernels, initrds also).. which is an ext3 file system.

Either way, lettuce know :)
