Using Windows Xp Professional on Compaq Presario C700,and i installed RHEL v5.2 on it,GRUB installed on First Sector of boot Partition of RHEL.The problem is am not able to find Boot Menu of Windows & Linux,where i can only boot from Grub i.e.. Linux not Windows Xp.I even Fix MBR by using Bootable XP CD (fixmbr) in repair mode,now windows Xp is booting (From HDD) but booting from Linux is not possible,as Boot Menu is not appearing.

Please suggest exact solution by depicting step by step to get display of Boot Menu at start-up,as i want to use Windows & RHEL5 on my Laptop.Thanks

boot of the redhat install cd.

type linux rescue

to go through the options it will ask you to mount your drive, make sure you select to mount as read/write, (dont mount it as read only)

pick all the defaults for everything else.

from the command line run
chroot /mnt/sysimage

run
grub-install

All this will get your grub menu back.

----
exit and reboot
----

boot in to linux  via grub prompt

after your all the way up add the following to the end of /etc/grub.conf

-
title Windows
rootnoverify (hd0,0)
chainloader +1
---


reboot you should be able to select windows or linux.

same error -  "/usr/src/grub/i386-redhat/stage1: Not found". when trying the command "grub-install  /dev/sda " as my Hard Drive is SCSI.
strange did you run the chroot /mnt/sysimage ? where there any errors when the rescue cd mounted your drives?

Author

Commented:
Yes i run, i will explian you clearly what i given commands in rescue mode  

1) mount
2) chroot /mnt/sysimage ( with No Errors )
3) grub-install /dev/sda

At this command getting display of   "/usr/src/grub/i386-redhat/stage1: Not found".
Do you see kernels in /boot? can you post the output of ls /boot and ls /boot/grub



Try running this instead.
grub-install --root-directory=/boot /dev/sda

all the above should be done after the chroot.

Just after searcing RHEL Installation getting an error " An error occured trying to mount some or all of your system.Some of it may be mounted under /mnt/sysimage.Press to get a shell.The system will reboot automatcally when you exit from the shell."

when i try to list the files in /boot it list nothing & showing empty as "total 0"
ya it did not mount /boot thats what that error you saw was about. Can you post the output of
fdisk -l

Author

Commented:
"fdisk -l" displays " cannot open /proc/partitions "
ok exit the chroot. then run fdisk -l. if you have typed chroot a few times you will need to keep typing exit. run fdisk each time and stop when you get output that is not an error.
typing "exit" will exit the shell.

Can any one give response quick

Author

Actually i sort out the problem by insatlling RHEL 5.0 again with giving space to GRUB in MBR which is already exist of a Boot Loader of Windows and after booting to Linux i just change boot time delay to 30 sec & Default boot to Windows in grub.conf file in /etc/.Now i can able to see the Boot Menu at Boot Time.
 
Thanks Mr.Martin to your quick replies.
