The first instinct might be... "OMG! REINSTALL!"
But that's a Windows
instinct. This is Linux
Here's what to do. Ask yourself how
you managed to make Windows go-away from the boot menu. What changed recently? Is there a backup-file handy?
Okay, let's suppose there isn't. The next question is: are you using grub
as your bootloader, or LILO
? In Linux, look for a directory called /boot/grub
. That is, from the topmost directory, look for "boot" and within that look for a folder, "grub." If so, you'll find a grub.conf
file in that folder, and the command info grub
will tell you all about it... with examples.
If, on the other hand, you see a /boot/map
file, and a file /etc/lilo.conf
, you're probably using LILO. Once again, man lilo
will tell you all about it. A little bit more complicated but it'll get you on the right track.
In both cases you do need to know where
the Windows operating-system is: on which drive, and which partition.
"Simply scrambling for a reinstall disk" is not
the right thing to do.
It will only make things needlessly
worse... Now that you find yourself unexpectedly thrust into this situation
... work your way out of it
as you go. These woods will never be so dark-and-scary again.
