my computer fails the booting of fedora since I had installed it

mcferry · 03-04-2006, 12:44 PM

Hi!

This noon I wrote a threads but I understand it wasn't very clear and so I retry.
I have a HP Pavilion and so there is a bootloader for windows xp and the system recovery.
After having installed fedora on an external HD and as default grub on the internal HD, I had reboot nand fedora didn't start.
the message was "error loading operating system" and the only thig I can do is ctrl+alt+can and boot windows.
what can I do? I had wrong installing grub in the other HD? if it is so, how can I do?

Thanks

Try to repair with the installation disk, i not shure that works, but you can try anyway

I tried again twice, it didn't work. It is possible that ther are problem between HP bootloader and Grub?

Is this on a single hard drive on dual?
How did you configure GRUB during the Install?

mcferry · 03-05-2006, 05:24 AM

it is on a dual and I configure it as default

have ran checkmbr on the Windows cmd prompt?

No, I don't know what it is, can you explain me better what I have to do?

In Windows bring up a Command Prompt then type checkmbr and load the display of that to here.

I have tried in this way, I suppose that there is something wrong

Can you boot you system from a floppy disk? If so, consider making a GRUB boot floppy to see if you can boot your Fedora from it.

Do you have the Fedora "Linux Rescue" CD? Can you boot from that CD, and does it find your new Fedora on the external HD? If it does, try the suggested "chroot" command, and look at "info grub" for instruction on how to re-install and verify GRUB on you internal HD, paying particular attention to the device map section.

Thanks, I'll try

Sorry my mistake, I had my head up my A.., the correct command is FDISK/mbr from the command prompt in Windows. That command will rebuild (or should) rebuild the MBR for you.
