After installing Mandriva 2009, won't boot!

[Guest guepe65]

Hi all ! I succesfully installed mandriva 2009 on a laptop, grub seems ok, windows booting also.

When trying to boot on mandriva, i got some messages very quickly, like :

Setting up other filesystems
Setting up new root fs
setuproot: moving /dev failed: No such file or directory
no fstab.sys, mounting internal defaults
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Switching to new root and running init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
usb 2-6: configuration #1 chosen from 1 choice
switchroot: mount failed: No such file or directory
Booting has failed

 

This is completely similar to this topic but different for one important thing : there is _no_ RAID on this laptop.

The only thing is, gub is installed on (hd0,4) (and not (hd0,0)) because it has a restore partition where the MBR was previously. I suppose grub detected it, and placed boot sector to this partition.

 

Moreover, I tried reinstalling grub, which gave me the same (installed with the mandrive one 2009 live cd, which was the one for installation). All grub config. seems ok, installation of linux s made on the second partition (/) then a 1GB swap, then restore. Windows is at the beginning, in brief something very, very standard by these days.

 

Do you have _any_ recommandation on what to test ?

 

Thanks a lot
