Hi there...It's a big chance I DO love challenges :lol: cause installing Gentoo AND being a noob in the Linux world is a REAL challenge. I got through almost all my problems but one last ( I hope!) is remaining at bootup. Here's the error:

sh-2021: reiserfs_read_super: can not find reiserfs on ide0(3,5)
XFS: bad magic number
XFS: SB validate failed
Kernel Panic: VFS: Unable to mount root fs on 03:05


some info: (I did a Stage1 installation following the Installation guide. I got an Athlon-XP-Barton 2800+, 2*512mb ram (I enabled "4GB RAM" in genkernel --config)

/etc/fstab
Code:

/dev/hda6                 /boot           ext2       noauto,noatime 1 2
/dev/hda8                 /                 reiserfs   noatime,notail   0 1
/dev/hda7                 none           swap       sw                   0 0
/dev/cdroms/cdrom0 /mnt/cdrom  iso9660   noauto,ro,user 0 0
none                        /proc            proc       defaults            0 0
none                        /dev/shm      tmpfs     defaults            0 0

grub.conf
Code:

default 0
timeout 30
splashtime=(hd0,5)/boot/grub/splash.xpm.gz

title=Gentoo
root (hd0,5)
kernel (hd0,5)/boot/kernel-2.4.22-gentoo-r2 root=/dev/hda7
initrd (hd0,5)/boot/initrd-2.4.22-gentoo-r2

title=M$ Windows 2000
root (hd0,0)
chainloader (hd0,0)+1

fdisk /dev/hda
Code:

hda1     *     1        1275      c     win95     FAT32(LBA)
hda2            1276   9729      f     win95     Ext'd  (LBA)
hda5            1276   3825     c     win95      FAT32(LBA)
hda6     *     3826    3830    83    Linux     
hda7            3831    3953    82    Linux
hda8            3954    9729    83    Linux


So as you see I'm dualbooting with Windows 2000, no problem here, I can boot in Windows from Grub without any problem. But when I wanna start my Gentoo, I get that error, almost at the end of bootingup... :cry: Oh yha! when I reboot with the installation cd, I can mount /dev/hda7 /mnt/tempo and read (list) what's in there so the partition is accessible.

I searched to recompile my kernel but I just dunno where to go to do it

So if u have any tips on why I can't get to the end of my boot pls tell me cause I know I'm very near to make it work. I'm new in your world guys so please be precise in your answer. Thx in advance, Peace!

See it already ?

You're trying to mount your swap partition as root filesystem - not gonna happen ;-)

In your Grub.conf
root=/dev/hda8

because it's your swap partition in /dev/hda7
:wink:

I receive the same error message, but unless my eyes are crossing, its not the same error

Here is my fstab

/dev/sda1 /boot
/dev/sda5 /
/dev/sda6 /usr
/dev/sda7 /home
/dev/sda2 none

Here is my grub.conf

default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz

title=Gentoo Linux 2.6.13
root(hd0,0)
kernel /kernel-genkernel-x86_64-2.6.13-gentoo-r5 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda5 udev initrd /initramfs-genkernel-x86_64-2.6.1

I think that I have everything done correctly, although I don't understand the ramdisk portion. I had to use genkernel because I couldn't get my kernel to compile correctly. Any suggestions on how to get past the error? Thanks.

I removed the real_root and the ramdisk part. It now boots. Unsure why it is in the manual like that. Anyone have any ideas?
