Subject: How to load Linux from GRUB? 2005-11-05 - By Steven J. Yellin
Back
One other comment: if all that has happened is you've destroyed your
partition table, leaving all data otherwise intact, it may be possible to
recover by using fdisk to reconstruct the partition table EXACTLY as it
was before. But you may not be able to figure out the exact size and
number of your partitions before the problem, or other data may have been
wiped out, or maybe this method won't work for some other reason -- I've
never tried it and hope I'll never have to. But just in case, the output
of "fdisk -l" on my computer is saved on another computer and the output
of "fdisk -l" on the other computer is saved on my computer.
