Bootloader problem Grub.
Bootloader problem Grub. Hello,

I have some questions about my Mandriva Linux. My father died last year and so I got automatically forced to use Linux (master computer). I have become a little bit known with it, had to reset the root password via command lines etc. But I have some problems I can't solve on my own.
In this topic I will ask my first problem:

The Grub bootloader doesn't open Windows when clicking on it. Sometimes it just reboots and you get the Grub bootloader again, sometimes when I messed with some things it says something like this:

Quote:
Booting 'windows'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
map (0x80) (0x83)
map (0x83) (0x80)
makeactive
chainloader +1

Error 13: Invalid or unsupported executable format

Press any key to continue..._
I have tried everything I thought that could help, placing the boatloader in another disk (which made me use the rescue cd, because nothing would startup anymore Image), placed the bootloader back, using the other bootloader Lilo which didn't work well and so on.

I have changed the link in the bootloader from sdb1 (Windows was given that command automatically at installation) to sdc1 because at the diskpartition the windows C stands at sdc1. But nothing changes. Images:

Who can help me. I can reach the windows files via /mnt but not just how it has to work. Deleting windows or Linux is no option, there are too many important files on both.

Bij voorbaat dank as we say here...

From a root console, do fdisk -l and show me what it prints.

Also, please post the contents of /boot/grub/grub.conf

It's in dutch, if you don't know what some word means I will hear it from you.

The second one, I can't find the grub.conf in the /boot/grub map...I am searching it, and I will post it in a following message. Thank you both for the fast responses.

You've got a lot of disks in there! Smilie

It's a bit plainer what the problem is now, hd0 is the wrong drive. grub doesn't use anything like sda, it just uses drives hd0,hd1,etc numbered in the order the BIOS reports them. It might be hd2, assuming the windows you want is the NTFS partitions and not the FAT32 ones. I have no idea how windows will react to being the third drive in the system though! Smilie (That might be what those map lines are to fix, not sure.) It might blow its little mind, or it might pretend the other drives don't exist since it can't read their partitions...

I can't find grub.conf. I found out via google that you might need menu.lst from that map.

Good, that's it.

Have you added any disks lately, or done anything that'd change the order of drives as the BIOS reports them? Those map lines may be incorrect now.. Try commenting them out and doing
Code:
map (hd2) (hd0)
map (hd0) (hd2)

instead.
