boot failure after install

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Dear P.,

Yes, this has happened EVERY time I have installed CentOS 4.0 (the only 
version I have ever installed). I also boot up into rescue mode and then 
issue just one grub command,

grub-install /dev/i2o/hda (or whatever your device is called)

This fixes the problem permanently.
