GRUB install problems... (post windows install on ubuntu)
sorry if this is in the wrong forum...
Hey guys. Fairly new user to Ubuntu though I've used it a few times over the years to save my data from Windows crashes.
Have been using latest Ubuntu build (8.10) exclusively for 3 weeks. Till I just reinstalled Windows XP...
Lost GRUB, so I can't boot into Ubuntu. I'm posting this off my Live! CD (Ubuntu 8.10). Followed the first two sets of instructions at:
But couldn't get either to work. I've included the terminal outputs below. Any help would be sooo appreciated. Thanks.
using the 1st method given:
grub> find /boot/grub/stage1
grub> root (hd0,7)
grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 16 sectors are embedded.
Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p (hd0,7)/boot/grub/stage2 /bo
Error 22: No such partition
so I tried the 2nd method offered on the page. using the second method (I used >>> to include my commentary):
ubuntu@ubuntu:~$ sudo -i
root@ubuntu:~# fdisk -l
omitting empty partition (5)
Disk /dev/sda: 100.0 GB, 100030242816 bytes
255 heads, 63 sectors/track, 12161 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x14cb14cb
Device Boot Start End Blocks Id System
/dev/sda1 * 1 146 1172713+ 7 HPFS/NTFS
/dev/sda2 147 12161 96510487+ f W95 Ext'd (LBA)

/dev/sda7 11024 12161 9140953+ 83 Linux
>>>ok, so my Linux partition root is on sda7 and my boot is sda1. Does it matter that the tutorial has the boot partition as Linux while mine is NTFS? Moving on...
root@ubuntu:~# mount -t ext3 /dev/sda7 /mnt/root
mount: /dev/sda7 already mounted or /mnt/root busy
mount: according to mtab, /dev/sda7 is already mounted on /mnt/root
>>> I already mounted the root drive in an earlier attempt. So this is fine.
root@ubuntu:~# ls /mnt/root
bin dev home lib mnt root sys var
boot etc initrd.img lost+found opt sbin tmp vmlinuz
cdrom grub initrd.img.old media proc srv usr vmlinuz.old
>>> just proving all is well
root@ubuntu:~# mount -t ext3 /dev/sda1 /mnt/root/boot
mount: /dev/sda1 already mounted or /mnt/root/boot busy
mount: according to mtab, /dev/sda1 is mounted on /media/disk
>>> I already mounted the boot drive in an earlier attempt. So this is fine.
root@ubuntu:~# ls /mnt/root/boot
>>> just proving that all is well
root@ubuntu:~# sudo grub-install --root-directory=/mnt/root /dev/sda
The file /mnt/root/boot/grub/stage1 not read correctly.
>>> now, should sda have been hda there? What is wrong with this stage1 file that it fails in both the methods? I even downloaded the grub installer and manually put stage1 and stage 2 into the root folder of the boot partition, but it still doesn't work. I'm baffled.
Like I said, any insight would be so appreciated. Thanks, guys.
grub> find /boot/grub/stage2
grub> find /boot/grub/menu.lst
to verify these files locations as well.
The find command output below does not look right. Your fdisk output only shows partitions up to sda7 which would be (hd0,6) in Grub.
You don't have a boot partition, you only have one Linux partition which is the root partition on sda7. You don't have any boot files on sda1, you should have stage1 of Grub in the mbr of sda which is not on a partition.
The change above should work if you have posted correct info from fdisk.
hey guys. thanks for the replies. since my issue was time-pressing, i tried tons of solutions. eventually i was booting with the super grub disc, which yielded some bootup issues in linux. but when i removed the disc, Grub opened beautifully, and all OSes loaded perfectly.... super grub ftw.
nevertheless, i super appreciate your help, and i definitely learned a bit reading them. see ya 'round the forums.
