Grub menu not coming; XP & RHEL Dual boot
Hi All,
I have installed XP & RHEL 5. I had absolutely no problems in it, but suddenly my grub menu disappeared and I was not able to boot either of them. I managed to run my XP then by booting it by CD and run FIXMBR. But now only XP boots directly without the GRUB menu. I had run Linux Rescue at prompt. Now, my menu.lst is located at /mnt/sysimage/boot/grub/menu.lst Pls help !!! Thanks in adv, Vikas |

Now, I have tried running these commands chroot /mnt/sysimage grub-install /dev/sda I am getting GRUB menu now (not colored like before), BUT RHEL still doesnt boots. I am getting these errors root (hd0,5) Filesystem type unknown, partition type 0x82 kernel /boot/vmnlinuz-2.6.18.el5 ro root=LABEL=/ rhgb quiet crashkernel=128@16M Error 17: Cannot mount selected partition Press any key to continue I have tried upgrading my existing installation in Rescue Mode but it doesnt helps. Also, I have tried upgrading or again creating the bootloader, but still all went in vain. Here is the output of fdisk -l Device Boot Start End Blocks Id System /dev/sda1 * 1 2611 c W95 FAT32 (LBA) /dev/sda2 2612 17902 f W95 Ext'd (LBA) /dev/sda3 17903 19457 12 Compaq Diagnostics /dev/sda5 2612 15291 b W95 FAT32 /dev/sda6 15292 15552 82 Linux Swap / Solaris /dev/sda7 15593 17902 83 Linux Hope it Helps |
I'm no expert but they will probably want your grub menu list also.

You might try booting the SuperGrub CD and using it to restore Grub/dual booting. Its not RHEL 5 specific like I assume Linux Rescue is, which has both advantages and disadvantages.

Here is the output of fdisk -l
Device Boot Start End Blocks Id System /dev/sda1 * 1 2611 c W95 FAT32 (LBA) /dev/sda2 2612 17902 f W95 Ext'd (LBA) /dev/sda3 17903 19457 12 Compaq Diagnostics /dev/sda5 2612 15291 b W95 FAT32 /dev/sda6 15292 15552 82 Linux Swap / Solaris /dev/sda7 15593 17902 83 Linux from your output of fdisk -l , it refers that you are having 2 filesystem for linux. /dev/sda6 --- swap /dev/sda7 --- root you do not have seperate filesystem of boot. so boot files are in root file system itself so you follow the step given below boot into sytem using cdrom with rescue boot: linux rescue after logining in chroot /mnt/sysimage (hopefully this is right) then go to the file /boot/grub/grub.conf and edit the following enties in that file title ............. root (hd0,6) // this is one specfying the boot file in MBR kernel ................. ro root = /dev/sda7 ........ selvaraju http://linuxmonk.blogspot.com |
