Problems with Grub?
Well, I posted a tutorial about clones, and who never forget some steps making a clone? After the end of the cloning process, grub just say “no way” for you. Important: just for cases which grub its installed on MBR.
There are many websites talking about specific errors, but I will give some hints which helped me sometimes.
Frequent Error: its the “Error 2″ on the stage 1.5 of grub loading. When this error occurs, please check your HDD configuration on FSTAB and MTAB. Normally when we change some old machines which use PATA HDDs to new SATA HDDs, Grub get confused with these devices. After check FSTAB(/etc/fstab) and MTAB(/etc/mtab) after a successful clone process, please pay attention on file device.map, usually at /boot/grub.
If you can’t find it, run grub-install with the option –recheck:
grub-install –recheck /dev/sda
When you execute this command and receive an error with device “hdaxx”, you have to check the configurations on /etc/fstab and /etc/mtab.
Its something simple and appears stupid, but when you are restarting your Linux studies, you lost few hours until discover this kind of problem.
