Posted: Wed Jan 08, 2014 6:26 am Post subject: Grub doesn't detect Gentoo |
|
|
I have Ubuntu 13.10 on /dev/sda1, which also contains Grub2
I just installed Gentoo on /dev/sdb1, and installed the kernel is 3.10.25-gentoo
Running 'update-grub' doesn't detect the Gentoo system.
How can I add Gentoo to the existing Grub? |

Do you have os-prober installed?
If you do not have it, install it and re-run grub configuration command |

install and run os-prober and then update grub in ubuntu if os-prober has found gentoo; I'm thinking: In order for grub-mkconfig to detect your Linux kernel(s), they must be named vmlinuz-version or kernel-version _________________ Defund the FCC. |

I just decided to install Grub on the Gentoo disk instead. |

Same:
Upgraded linux mint 17
poof gentoo entry gone
typed by reading my second box
os-prober
/dev/sda6:Gentoo Base System release 2.2: and so on
grub-mkconfig
Big wall of text and in section 30_os-prober
found gentoo base system and so on
no boot entry, sigh
I really hate those automated scribts and those noobish ubuntu / mint peeps, they just erased another grub config without backup of the previous File. Are they nuts on deleting a system file without backup? size below 7kb. I am not sure if I added in the custom section or not though.
I will later generate the coresponding entry again, but just annoying such "auto scripts" of htose noobish binary distros. without confirmation or anything, graphical GUI updater of linux mint ruined it in the first place. They just replace that file and thats it
kinda annoying now i get a kernel panic with teh kernel which worked before i updated linux-mint. sigh. |
