 |
|
Hi all
Its me again 
I successfully installed grub now, and it works (wow).
I can boot Windows without problems.
But.....
When I boot linux theres a problem.
below
>> Mounting filesystems...
mount: Mounting devfs on /dev failed: No such device
Error opening file: ".defsd" No such file or directory
>> Determining root device ...
>> Block device /dev/hda2 is not a valid root device...
>> The root block device is unspecified or not detected.
Please specify a device to boot, or "shell" for a shell.
[Inputfield]
Ow, and in loading modules theres after every module a "module not found" 
I used Genkernel with Gentoo 2004.1, gentoo-dev-sources 2.6.8-r4 on AMD64

Could you post your /etc/fstab and grub.conf, please?

Your fstab needs a few extra lines:
| Code: |
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0

It sounds like you may not have devfs support enabled in the kernel. To check, do:
| Code: |
gunzip -c /proc/config.gz | grep DEVFS
|
If it's off, you should try recompiling the kernel with devfs support enabled.
