My new installation is running well, in particular it boots fine. However the grub2-mkconfig seems odd.
It finds linux (all kernels) and the stub windows partition. But then I get messages that both ext4-fs and FAT-fs have trouble with /dev/sda4, which is the extended partition. Perhaps the fact that the windows partitions sda[23] don't really have windows on them yet is part of the answer?? Has anyone else seen something like this? thanks, allan
