Hi,
I have just started to get the hang of linux, im using Fedora Core 4, and i get a really wierd problem, i have grub set up to dual boot Windows xp (hdb) and Fedora (hda), both work, but once i boot into windows, then restart or shutdown, then when the grub screen with the menu should load it just goes to a grub> console. After lots of attempted fixes i found that grub could not see the boot partition on linux, i ran fdisk (after loading the rescue disk) and it had changed the boot partition type to:

93 Amoeba

and if i change this to:

83 Linux

and then reboot the grub menu returns and works as normal until i load windows then it starts all over again and i have to boot into rescue mode just to change the partition type, is this some sort of windows fault or is there something else going on here

Is it maybe to do with the fact that i have tried accessing the linux partition through windows using some various programs, and it could only see the boot partition and now windows keeps changing the partition type so that it can read it?

Hey, I'm a relative Linux newbie too...but just a quick question. How did you figure out that it was changing the partition type??? I had this same problem! I didn't know what to do, and I formatted my FC3 partition, installed FC4 over it, and now GRUB wont even load correctly. Maybe it's due to the fact that I installed GRUB over an existing installation of itself... It just hangs there like this:
GRUB _ (the underscore being the blinking cursor)




Got any idea what to do??

hi,

after a lot of googleing i found out that someone had a similar problem except that his was fine, mine wasnt and its a pain to keep using the linux rescue each time because the partition type changes.

I had that to, im guessing that you have windows on a hard drive aswel and you installed fedora after and it wont load grub, the way that i fixed it was to:
1. disconnect my windows hard drive
2. put my other hard drive as master (the one that your going to put linux on)
3. install linux again and put grub on the MBR (master boot record)
4. make sure that it loads like normal
5. reconnect your windows hard drive as slave
6. now it should auto load linux fine, now you can either live with changeing the bios to boot windows or linux or:
edit the grub.conf, my setup is:
master hard drive has fedora core 4
slave hard drive has windows xp and this is my grub conf:

This works fine except if i load windows it messes with the partition table and i cant find out why. But i hope this helps.

Well i've fixed it, unintentionally, but hey, all i did was remove the line:

hide (hd0,0)

from grub.conf and it worked, which was rather odd and i dont know why that did what it did but its fixed, thats all that matters
