Hi Luv' ers I am having a grub install problem. I installed 13.10 and in the process destroyed grub and I can't boot anymore. I can however boot using supergrub2 cd. (..so no panic!) If I boot from hard drive, I get error: dev with UUID xxxx... can't be found. (..something to that effect) I know that, because UUID xxxx... is now UUID yyyy .... I changed all reference to xxxx... to yyyy... in all grub.cfg files. (this box has 3 versions of Ubuntu) When I try to reinstall grub with grub-install /dev/sdb (note: boot HD is second one, but even if I select sda, I get same error) I get errors as follows: /usr/sbin/grub-bios-setup: warning: your core.img is unusually large. It won't fit in the embedding area. /usr/sbin/grub-bios-setup: error: embedding is not possible, but this is required for RAID and LVM install. Even if I try force option (--f), I still get above error. (Yes, this box has LVM) Any ideas? Cheers, Daniel.
