| Post subject: | ubuntu upgrade gone catastrophically wrong |
Hi all, was dual booting XP and ubuntu netbook remix fine for ages on my Samsung NC10. Yesterday pressed the upgrade to 10.whatever in Ubuntu and it didn't work. Booted and did a restore packages. Now when I start it just has a command line prompt with "grub rescue". If I hold down F4 when I restart, it won't take me to the Samsung bit, so I can't even get to the recovery partition. Anyone got any ideas? |

I don't know anything about grub, so if it were me I would put the Windows disk in and do a fixmbr so you can boot into the Windows partition again. I don't know if/how the Ubuntu install is recoverable, but in the worst case scenario you could probably use a LiveCD to get access to the data on the Ubuntu installation and save it somewhere before a re-install. Hopefully someone with some knowledge of Grub will be able to suggest how to recover it? |

My 10.04 upgrade went wrong too. It seems to come from the new GRUB. Halfway through the upgrade I had a message asking what drives I wanted to install new GRUB onto, so picked the one with Ubuntu installed onto, but on restart it never booted again. I was going to do a clean install at some point anyway, so it kinda forced my hand and I never figured out how to fix it. Did you get this message:

Certainly something similar. In the end I downloaded the latest NetBook Remix, booted it on a flash drive, formatted the partition with Ubuntu on it, and reinstalled. It now works fine, except that grub loads twice and I have to select which OS I want twice. |

That is of some use, thanks. It looks like Grub was installed on the MBR of the hard disk with the upgrade and it's in the Windows partition from the old install. As I'm unsure of how to remove the second one and it only comes in if you boot in windows and it defaults to Windows anyway, I won't bother! |
