GRUB2: booting Linux

GRUB2: booting Linux

[Sergey Matveychuk]

OK. I've fixed my problem with dd. GRUB2 boots well. But how can I boot 
Linux now? There is no 'kernel' command. And 'load' command too.

chainloader +1 said:
error: invalid signature

With chainloader I can boot only WinXP. Nether Linux nor FreeBSD.

There is the "linux" command.  You just have to build in the loader.
And of course you need rescue mode, just like you used it for the
chainloader.

I can't see it on the 'help' command.
But what with a 'kernel' command?
And why 'chainloader +1' says "invalid signature"?

It is weird that it does not show up in the help.  I will have a look
at that really soon.

I do not remember any problem with the chainloader.  From what I can
derive from the sourcecode, it checks if the block is a valid block
with bootcode.  It seems to be possible to use --force to ignore the
result of this test.

I assume you understand that --force can lead to unpredictable
results.

Yes. Really unpredictable results. My hard disk data is complete broken :(
