My FC6 / XP dual boot to FC10 / XP dual boot upgrade plan... is this sane?
 
Hi all

I currently dual boot FC6 and XP quite happily.

I've just got FC10, but I don't want to reformat my entire HDD and reinstall XP, and then install FC10.

I do not want to attempt any "upgrade" of FC6 to FC10.

What I'm planning to do is to fully format the current FC6 partitions with FC10's installer as ext4 partitions, and then fresh-install FC10, and have FC10 put "its" GRUB in the MBR.

I'm assuming this will work...? Any logic holes? I just want to totally format / overwrite the entire FC6 instance I currently have, and replace it with FC10, leaving XP alone on its partition, and have the "new" GRUB still detect XP and the new FC10 install for booting purposes.

Likely to work? Any pitfalls to avoid?

Thanks!

Just to make sure: you now boot using GRUB, which is invoked from MBR, don't you?
I know nothing about FC, but currently boot many partition/systems with GRUB with no problems. I would just back up current /boot/grub/menu.lst just in case the installer doesn't recognize all your systems from current menu. Then all you have to do is to restore the section booting WindowsXP to your new menu.lst and it spares you from searching man grub :).
As long as you do not damage your XP partition there is nothing to be afraid of.

Good luck.

Hmm, to do this I boot off my FC6 rescue CD, change to /boot/grub and then do

Code:

# grub

Grub> root hd0,1
Grub> setup hd0

This usually copies the GRUB bootloader back into the MBR. I usually do this after I had to reinstall Windows on my dual-boot system and in doing so had Windows' installer overwrite GRUB's bootloader. This then re-overwrites the Windows bootloader and allows me to choose if I want Windows or Linux started when the PC it turned on.

i've tried to this command grub-install /dev/sda sda for my prime sata disck but it didn't work and i don't want to reinstall FC10.

Any output/error messages?
Hint: check permissions / execute grub as root (sorry if I'm too trivial)

i'll post today any error with grub-install script i'0ve just finished to downlad the DVD iso of fc10.
