I have installed Ubuntu 10.10 on my system. However, I need to install Windows 7 back, and I expect that it would alter GRUB and it did.
Right now, my partition on my Software RAID 0 looks like this:
nvidia_acajefec1 is Ubuntu 10.10 and nvidia_acajefec3 is Windows 7.
I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content.
I've tried running:
sudo grub > root (hd0,0)
GRUB complains it couldn't find my hard disk. So I tried:
And it complains that it couldn't find anything.
So I tried:
It said "file not found".
Here's the text from the console:
ubuntu@ubuntu:~$ grub Probing devices to guess BIOS drives. This may take a long time. [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) root (hd0,0) Error 21: Selected disk does not exist grub> find /boot/grub/stage1 find /boot/grub/stage1 Error 15: File not found
**Fortunately, I got one person suggesting that what I've been trying to do is for GRUB Legacy, not GRUB2. So I went to the suggested website, (http://grub.enbug.org/Grub2LiveCdInstallGuide) try to look around, and try:
ubuntu@ubuntu:~$ sudo fdisk -l Unable to seek on /dev/sda
This is just the step 2 of the instruction in the http://grub.enbug.org/Grub2LiveCdInstallGuide and I cannot proceed because it cannot seek /dev/sda.
ubuntu@ubuntu:~$ sudo dmraid -r /dev/sdb: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0
So what now? Do you have an idea for how to make fdisk see my RAID array on live cd (Ubuntu 10.10)? Honestly, I am lost, very lost in trying to restore GRUB2 on this software RAID 0 system right now.
