However, the install succeeded only for the sixth time. It took me 3 times to install Gentoo from a stage 1 and I was not getting any overheating problems with my PC. If you try to install it on a laptop, or a PC which is has cooling fans covered in fluff and dust in the middle of the summer, you may well be experiencing overheating problems. > 'Now' the main problem is that GRUB returns with error code 15.

Grub error 15 means that the drive and partition are correct, but the file in question (your kernel image) is not found. In the first instance I can think of two possibilities: 1. You've made a typographic error when you entered the name of your kernel (kernel-genkernel-x86-2.6.19-gentoo-r5) in grub.conf. This is easy to check. Mount boot with a live CD and ls the contents of it. Then check the name of the kernel character-by-character. 2. When you installed your kernel (copied your kernel image in /boot) you had not mounted your /boot partition. This means that all your /boot fs has been installed in your / partition. It is also easy to check. Unmount /boot and then ls the contents of it. If you can see a kernel image then this is your problem. Mount /dev/sdb5 on a different mount point (e.g. mkdir /mnt/test) and then cp -a /boot /mnt/test. List everything under /mnt/test and compare with all files and directories under /boot. As long as access rights are correct for each file and directory you can rm -Rf /boot/* > I have got two HDD-s with SATA interface.

If Grub is in the MBR of sdb then it must be chainloaded from the MBR of sda, or assuming that you have Grub also installed in the MBR of sda then copy your grub.conf entry to the /boot filesystem that the MBR of sda boots from. > grub.conf: > > default 0 > timeout 30 > splashimage=(hd1,4)/grub/splash.xpm.gz > title=Gentoo Linux > root (hd1,4) > kernel /kernel-genkernel-x86-2.6.19-gentoo-r5 root=/dev/ram0 init=/linuxrc > ramdisk=8192 real_root=/dev/sdb6 doscsi > initrd /initramfs-genkernel-x86-2.6.19-gentoo-r5 > > > Everything looks to be good, but I have no idea what does > root=/dev/ram0 init=/linuxrc ramdisk=8192 > mean and why appears 'ramdisk'.

You'll realise how fine it is when you learn how to fix it without reinstalling. Gentoo has (almost) self-healing properties . . . :-) > I'm now totally depressed....

You can try info grub - it is a bit more condensed (but I am not sure if it is up to date). Hope this helps. -- Regards, Mick
