I prefer to keep Windows on the MBR. So I install grub to a separate partition. I then allow the Windows Loader to chainload grub (example).
I noticed a problem with the Fedora 12 Anaconda Installer. If I chose to install grub to the First sector of boot partition instead of the MBR, I get an un-bootable system.
It is easy to see the problem if you compare fdisk output. (I reduced the output for clarity)
Before I installed Fedora 12 32-bit to /dev/sda10
Device Boot Start End Blocks Id System /dev/sda1 * 1 2089 16779861 7 HPFS/NTFS /dev/sda4 6268 36479 242677890 f W95 Ext'd (LBA) /dev/sda10 23762 25589 14683378+ 83 Linux /dev/sda14 34076 36192 17004771 83 Linux /dev/sda15 36193 36478 2297263+ 82 Linux swap / Solaris
After I installed Fedora 12:
Device Boot Start End Blocks Id System /dev/sda1 1 2089 16779861 7 HPFS/NTFS /dev/sda4 6268 36479 242677890 f W95 Ext'd (LBA) /dev/sda10 * 23762 25589 14683378+ 83 Linux /dev/sda14 34076 36192 17004771 83 Linux /dev/sda15 36193 36478 2297263+ 82 Linux swap / Solaris
The boot flag is set to the wrong partition.
To fix this problem
Just boot with a CD/DVD, choose “Rescue” mode and run fdisk at the shell to change the boot flag. If you need more help, details follow:
- Boot with the system using your Fedora DVD or CD#1.
- Select “Rescue installed system”. (Select the proper settings, networking is not necessary)
At the “Rescue” screen, you can “Skip” the mounting of your installed system.
At the “First Aid Kit quickstart” menu, Select “shell”.
- At the shell prompt, use fdisk (BE CAREFUL!)
bash-4.0# fdisk /dev/sda Command (m for help): a (toggle bootable flag) Partition number (1-15): 10 (the partition you installed Fedora) Command (m for help): a (command needs to be run twice) Partition number (1-15): 1 (the partition with MBR) Command (m for help): p (verify everything looks correct) Command (m for help): w (write table to disk and exit) The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disk.
I doubt this will affect many people since most people choose to install Fedora directly to the MBR. However I am reporting here in case someone else might find this useful. I noticed this a few days ago on Fedora 12-Beta 64-bit, but I had been too busy to check the bug reports. Will do that soon.
If you run into this problem (or similar) please leave a comment or contact me.
UPDATE: Should be fixed for Fedora 13. Bug 533658
It’s that time of year again, the Fedora Project announced the release of Fedora 12.
This release has received a great deal of polish, and with that plenty of media and documentation to go along with it.
Please see what’s new in Fedora 12. Some of the highlights include:
- Optimized performance – The 32-bit packages have been compiled for i686 systems
- Faster updates – The yum-presto plugin is default and RPM has updated its compression format
- More comprehensive networking and broadband support
- Next-generation (Ogg) Theora video
- Bluetooth on-demand
- Moblin graphical interface for netbooks
- Gnome 2.28
- KDE 4.3 (with updated “Air” theme)
- Better webcam support
- Better tablet support
- Improvements to Virtualization
When reading through all the information and documentation, it is easy to tell that a great deal of polish went into this release! Happy installing.
This post really has no purpose other than just a snapshot for me.
My current c:\boot.ini:
[boot loader] timeout=15 default=c:\linux3.bin [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /noexecute=optin /fastdetect multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect c:\linux1.bin="[ sda7] Fedora 11 (32) [06/2009]" c:\linux2.bin="[ sda8] Fedora 9 (32) [05/2008]" c:\linux3.bin="[ sda9] Fedora 11 (64) [06/2009]" c:\linux4.bin="[sda10] Fedora 10 (32) [11/2008]" c:\linux5.bin="[sda11] CentOS 5.3 (32) [07/2009]" c:\linux6.bin="[sda12] OpenSuSe 11 (32) [10/2008]"
That F9 and F10 will be replaced with F12 (beta at the moment). I might even drop in a Ubuntu Karmic Koala in there somewhere (if I get the time).
I know, I really need to retire my Windows 2000!
I think I also need to repartition that system!
Or best idea: I should get a new computer that supports KVM and switch to virtualization instead of this octuple-boot nightmare !!!
Time to start saving …
