Kernel Must Be Loaded Before Booting Windows 7
must be loaded before booting" error Hi all! I just installed fedora 10 using the GUI install, and when I try to boot, it gets me to the grub command line grub> when i enter 'boot', it gives me grub error 8: kernel must be loaded before booting. Not sure how to fix this, any help is appreciated. (I'm pretty new to linux). Also, I used to have fedora 9, and i had an option to boot fedora or 'other', which is kernel must be loaded before booting red hat windows. How do I go about setting up something similar in this case? EDIT: Also, when I type root, it tells me that the partition (hd2,0) (i assume the one i installed FC10: 3rd hdd, first partition) is an unspecified file system ... I think something happened to grub when it removed my old partition with FC9...

It sounds like you may have upgrade-installed from Fedora 9. Anyway, it happens often enough. I agree with your desire to manually boot the system from that grub> prompt, but you can't just enter "boot" as you found out. You must do that after a couple of other commands (e.g., root, kernel, and initrd). For example, starting with the root command at the grub> prompt... Code: grub> root (hdx,y) You change x & y to the drive & partition of your boot partition where the kernels, initial ramdisks, and GRUB files are located. If you aren't sure of it, then you can find it like this... Code: grub> find /grub/stage1 grub> find /boot/grub/stage1 Do both. One will produce an error, and the other will identify your boot partition. Use that in your root command. Continuing on... Next is

I've never used Grub before but did some digging online. Looks like I have to run the kernel command before I can boot the system. However, the kernel command is http://unix.stackexchange.com/questions/31226/trouble-booting-server-from-grub-prompt not running. As I installed the OS I checked the box that said something like "Install boot loader on /dev/sda". The following is what I've done: grub> find /vmlinuz-2.6.32-220.el6.x86_64 (hd1,0) grub> root (hd1,0) grub> kernel /vmlinuz-2.6.32-220.el6.x86_64 root=/dev/sda1 Error 27: Unrecognized command I've tried it with and without the root=/dev/sda1, just /dev/sda, also tried a ro inserted in the middle but nothing works. I've read the docs but at a bit of a loss.

This is due to a missing file, a corrupt package or corrupt media. Please verify your installation source. If you exit, your system will be left in an inconsistent state that will likely require reinstallation.
