Cannot boot Fedora core 5 from /dev/sda2

[nigelc]

Hi,
This might have been covered before, but. I have a system with 2 drives. Windows on the first, Fedora core 5 on the 2nd. Windows on /dev/sda1 Linux on /dev/sbd3 which I think is called /dev/VolGroup00/LogVol00
I had a virus on the windows partition could not get rid it. Re formated c: /dev/sda1 reinstalled windows xp. Made a copy or the mbr using dd , but it was corrupt. It just kept saying grub all over the screen. Have now installed fedora and re-formated the partition, but it now boots straight into windows. I remember there were some kernel parameters for grub but cannot remember what they were. Have installed fedora several times, but still the same.

thanks nigelc

This article will help you solve your problem. Basically you need to boot from your Fedora Core installation disc, get into rescue mode, access your Fedora installation and reinstall grub to /dev/sda.

in two Harddisks Dual Boot setup, i wont suggest you to install GRUB in MBR of Windows Harddisk. GRUB doesn't work properly in many cases and its hard to fix Windows like as in your case.
Plug-in Fedora's HardDisk as Primary and install GRUB in its MBR. Plug-in Windows Harddisk as Secondry. add an entry for windows in GRUB. follow instructions from here.
in this method, both Harddisk would be bootable separately and in case, anything goes, wrong with Windows, unplug Linux Disk, fix windows and plug-in Linux disk back. nothing to change in GRUB. it works perfectly.

I did a grub-install, it almost works, cannot boot. The splashimage does not work
it just comes up with grub prompt I can boot windows xp typing in the commands rootnoverify (hd0,0) chainloader +1

Here is a copy of grub.conf there is something still not right

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd1,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5

as i mentioned earlier, GRUB doesn't work properly if you install it in MBR of Windows Harddisk. i tried a lot of workarounds in this kind of setup but it worked in 20% cases only.

you should install GRUB in MBR of Linux Harddisk coz GRUB always work in this setup and there are a lot of benefits. read my last post.

i hope someone will chime in and suggest you correct and working solution in this kind of setup.





Good Luck !

Hi,
The system now boots Fedora & Windows. It was the grub.conf file and the way I was trying to install grub. But now there is a problem with the screen resolution. When I run system-config-display it shows the correct video card, but can only get 2 resolutions 640 x 480 or 800 x 600.
Do I have to edit that xorg.conf file ?

check the Monitor's Manual for supported VertiRefresh and HorizSync rates. edit xorg.conf file and correct the refresh rates. execute 'system-config-display' command again. in case, it doesn't work, select 'Generic Monitor' in Monitors List.

Hello,
Tried to edit xorg.conf several times. Then went System>Administration>Display
Tried a few different monitor types. MIne is a ViewSonic VA902 and found one ViewSonic VG191 now there are lots of resolutions.I should of made a note of what it was before.
