broken stage1 file from grub, cant boot ubuntu

Asked by trylik

hi

i have a serious problem now

i installed MS Vista and in order to have 13G (sic!) of free space i deleted SWAP partition

when i used grub-rescue CD i've got my grub back, but when i tried to choose on of ubuntu, there was an error, that files were not found (or something like this)

i think this might be caused by broke stage1 and stage2 files,

(here is stage1)

(EOF stage1)

i tried to install a new grub, but when i type "find .../stage1" htere isan error -"file not found"

i also tred to install from liveCD by grub-install

here is what i got:
root@ubuntu:/home/ubuntu# grub-install --root-directory=/bott /dev/hda
Due to a bug in xfs_freeze, the following command might produce a segmentation
fault when /bott/boot/grub is not in an XFS filesystem. This error is harmless and
can be ignored.
xfs_freeze: specified file ["/bott/boot/grub"] is not on an XFS filesystem
Installation finished. No error reported.
This is the contents of the device map /bott/boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

I believe you basically need to have a swap partition for ubuntu to work. Good thing you have added it. However, you might have problems still if it's UUID changed. If so, you will probably still have problem with mounting the swap partition. I'm not sure how to fix that without just installing again so you might want to post a new question if you seem to still have swap problems.

In order to fix grub you might want to check http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_restore_GRUB_menu_after_Windows_installation

I suggest using the method where you boot your feisty live CD.

I'm not sure your stage1 is corrupted. Since it isn't a text file you can't just open and view it so looking like that might be normal. If the steps in ubuntuguide don't fix this post back and we can try again.

Hope that helps.

Can you help with this problem?
