GRUB2 can't boot FreeBSD, neither directly nor via the loader
Only chainloading works. Here is part of my grub.cfg, first entry (chainloader) works, second (BSD loader) and third (BSD kernel) don't work:
Code:
### BEGIN /etc/grub.d/54_FreeBSD-9.1-chainloader+1 ### Selecting the third entry shows some colorful spots on the screen and then reboots after 5 seconds or so. What could be wrong? |
try insmod bsd
But grub2 is supposed to auto-detect freebsd. Is grub2 properly installed with all parts? do it manually to check. |

So I created the necessary files in /etc/grub.d/ by hand to get the grub.cfg from which I showed a snippet in my first post. Which fails ignominiously. I suppose GRUB2 is properly installed, it boots uncomplainingly openSuSE 12.2, Ubuntu 12.04, Fedora 17, Mint 14 and chainloads the FreeBSD-loader. Exactly how would I check whether it is properly installed? |
You can try compiling grub2 first from source
Check grub-mkconfig remove existing grub Install |
Well, no, this would be just fishing in muddy waters. As stated in my second post GRUB2 boots 4 Linux distributions and successfully chainloads the FreeBSD-loader. Just direct loading is botched. I suspect a wrong syntax (or parameterizatiion) in the grub.cfg but I have no clue where to set it straight.

Okay, I found out why it won't work. First, though, I have to amdend this:

Launching "grub2-mkconfig" and scanning the output revealed: Code:
Found FreeBSD on /dev/sda3 Thanks for your support, amani :). |

Hi JZL240I-U,
Sorry off topic here. I read you mentioned about "one had to change the values of the bits five to seven times to make it forensically impossible to reconstruct the contents of the disk." Where did you read that? |
That is not from this thread. When you have questions like these I'd suggest you open your own new thread or mail the member in question (currently me ;)). Anyhow, I don't exactly remember where I read that, but I can offer some links, where you might find more information:
