Remove Grub and Fedora - Install Windows

Hey, I got some tips this time for you. Many of you like using Fedora, for its ease of access for various tools, functionalities and the high processing performance output. However, it fails miserably sometimes, as in my case, while installing and will return a kernel panic error.

Kernel panic: VFS: Unable to mount root fs

which can be solved by checking the root partitions

kernel (hd0,0)/boot/bzImage-2.6.1-rc2-gentoo-1 root=/dev/hde2

and looking for

CONFIG_BLK_DEV_IDE and CONFIG_BLK_DEV_IDEDISK entries.

by changing the entry from

root (hd1,0)
kernel /2.6.5/bzImage ro root=LABEL=/ hdb=ide-scsi

to
root (hd1,0)
kernel /2.6.5/bzImage


the problem can be solved easily. If the problem persists, uninstall of Fedora is needed. Even then the grub would load every time u boot the system.

grub>

Everyone knows grub has great advantage of choosing between the Operating systems when there are more than 1 in your system. Hence, without removing grub, we can automatically load windows if installed by

Assuming Windows is present in HDD 1 and partition 1.

grub> rootnoverify (hd0,0)

grub> makeactive

grub> chainloader +1

grub> boot

If Windows is not installed, create a new partition by loading Linux DVD.

  • Load the DVD
  • Open the partition manager
  • Delete all previous partitions
  • Create free partition with vfat filesystem
  • Remember to remove swap partition

Then the problem is very simple,

  • Insert Windows DVD
  • Install by normal process

Even after this, if the Grub loads again, and you are not feeling like having it in your system, then To start your system from the Windows DVD and select the 'repair' option, and then type

grub> fixboot c:

grub> fixmbr

grub> bootcfg /rebuild

to alter the master boot record and will remove the grub which is installed. For Windows NT, boot with the grub by directing the GRUB to load NTLoader.
