[gentoo-user] Grub problem. Gentoo doesn't boot. VFS Cannot start...

[Isern Palaus Montasell]

Hello all,

This is the first time I install Gentoo Linux. This is my grub.conf file:

> default 0
> timeout 10
> splashimage=(hd0,2)/boot/grub/splash.xpm.gz
>

> boot
>
> #Windows XP Profesional
> title=Windows XP Profesional
> rootnoverify (hd0,0)
> chainloader +1


Windows XP boots well but Gentoo Linux no. Start booting but prints this:

> [...]

I don't know where is the problem, here is my /etc/fstab file configuration:

/dev/hda1 is a Windows Partition
/dev/hda3 is a Linux Partition for boot
/dev/hda4 is a Linux Partition for root
/dev/hda4 is a Linux Partition for swap.

Thanks in advance and sorry for my school English.

Hi,
i don't think that grub is your problem but the kernel config. Ensure
that your (S)ATA-Controller is supported by your kernel

Re: [gentoo-user] Grub problem. Gentoo doesn't boot. VFS Cannotstart...

[millerhe1]

Sorry for top post but if /dev/hda4. If root can't be swap also check cfdisk and if roots not /dev/hda5.

Re: [gentoo-user] Grub problem. Gentoo doesn't boot. VFS Cannot start...

[Jon M]

Hi Isern,

I actually have the exact same problem, and someone was kind enough to 
help me so I'll pass on the same info.  Basically my problem was that I 
hadn't enabled the proper IDE Chipset (or SCSI if you use S-ATA) in the 
kernel.  When I booted off my Gentoo install cd, I can 'lspci -v' which 
showed me what type of chipset I was looking for to enable in the 
kernel.  Give that a try and it should solve your problem.

I second this one. Exact same problem initially. Someone here helped -
ensure the necessary drivers are compiled into the kernel (not modules). It
took me several trials to get the right driver. Once I got the right one,
life got better.
