May just want to skip to the bottom of the article to the TipsAndTricks/ReinstallGRUB link. :-)

Hard to say without knowing what error you got. Did you do the chroot first?

No-one is going to be able to help you without knowing the exact commands that you issued and the exact error message(s) that you received. If you cannot remember them then you will need to repeat the process and write it all down and then post it.

Are you sure you want to install to /dev/sda1 and not to /dev/sda so it goes to the MBR? Might want to try

Code: Select all

grub-install --recheck /dev/sda

If more help is needed then please enable networking in rescue mode and show the results of

Code: Select all

fdisk -l
blkid | sort
