Just make sure the first partition starts at sector 63 like any normal partioning tool does. I don't know sfdisk but I doubt it wouldn't be possible with it, else you couldn't even create a proper 2nd partition probable. > > grub-legacy should tell you too that it can't embed stage1.5 just not > > that visible. > > It has however never shown any unreliability in years on hundreds of > hosts. grub 2 says it won't function properly. With grub-legacy it's exactly the same. We just decided to make it more clear in grub2 that blocklists aren't that great. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
