dualboot windows F12

[lemtree]

I have installed F12 on the remaining space on my disk and now Windows does not boot anymore.

I get to Grub and choose windows and then just get black screen with flashing cursor.

Am I or have I done something wrong?:confused:

The boot loader is probably trying to boot Windows off of the wrong partition. Can you post the output of
su
/sbin/fdisk -l
cat /boot/grub/menu.lst

Try this change and see if Windows boots, assuming that /dev/sda is not disconnected from the system board.
title Windows
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd0,0)
chainloader +1

Additionally, there is a thread here, http://forums.fedoraforum.org/showthread.php?t=236689, about dual booting. Slowjet, a very knowledgable member here, suggests a slightly different way of handling drive mapping. He's probably a lot more accurate than I so if what I've suggested doesn't work try using his method which includes makeactive and boot.

I tried your amendment and I get Error 13 when I chose to boot Windows.

I will follow the link you provided.

Thank you.

title Windows
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd0,0)
chainloader +1

Try this simple change to your lines

title Windows
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

Note that on the rootnoverify line I changed hd0 to hd1 which is where windows should show up. This worked for me in the past.

[lemtree]

Thanks that did the trick.

[JK3MP]

Note that most computers windows is on hd1 b/c hd0 is usually the factory image and/or restore partition. =) Glad to hear you fixed your issue.

Thanks lemtree for letting us know it worked.
