grub is gone
Message 1 in thread
Hello i have a problem my grub is gone. I have try to install Winsows and this
has killed grub. So now the only way to run linx is booting via PXE. I have
try to run groub-install /dev/sda1 but i will not work. When i try to boot
then via the hdd, i get the error 22 from grub. What can i do?
The FC2 installation is on /dev/sdd2.

Yes, as you can read in the documentation:
QActionGroup::~QActionGroup ()
Destroys the object and frees allocated resources.
void QActionGroup::add ( QAction * action )
Adds action action to this group.
Normally an action is added to a group by creating it with the group as parent, so this function is not usually used.
See also addTo().
This has to do with your question the same as your question with this list!
Regards!

Not sure why you cross posted this to the Qt list but I'll try to help. The
Windows installation program overwrites the primary hard drive boot sector
(even if the installation is aborted!) so your grub info is gone.
IIRC you can use a recovery disk to boot into linux. Then uninstall the grub
rpm and re-install it. This should re-install grub to the boot sector. The
only other alternative I know of is to re-install linux. I've learned the
hard way that on dual boot systems you always install Windows first.

Read the grub manpage. When you run the grub program, you can use the
"setup" command to write your boot sector. It would look something
like this:
grub> root (hd0,0) (Specify where your /boot partition resides)
grub> setup (hd0) (Install GRUB in the MBR)
grub> quit (Exit the GRUB shell)
(Be sure to remember that grub numbers the drives and partitions a bit
different than usual. The first disk is 0, and the first partition is
0.)
Reinstalling grub would probably not do this for you.

Ahh, this is good to know. Note to self: Read the grub man page _before_ you
hose your system. :-)

There's no need for any recovery disks or whatever. Just make a grub floppy
first, see: info grub, info:/grub.
Boot from grub floppy and *ONLY THEN*, while you're in grub's command line,
install grub on your hard drive. That's the only sure way. From under unices
it sometimes works sometimes doesn't as grub has to guess how the BIOS views
the disks available under unix.
This method has never failed me and IIRC it's the method recommended in the
info page.
