Disk Read Error with Dual Boot Sled 10 & XP


Hi,

I installed Sled 10 over the weekend and while Linux is working fine, when I attempt toDual Boot XP I get the following error:

Chainloader (hd0,0)+1
A Disk Read Error Occured
Press Ctrl + Alt + Del

I presume the problems something to do with the partition but don't have enough experience with Linux to fix it.

If anyone can advise it would be great, if you need any info just let me know what you need.

Thanks in advance!

From a terminal session in Linux, enter the following command and post (all of) the output
Code:
fdisk -l
(that's a lower case ell).
If nothing comes back, try "sudo fdisk -l" instead.

Nothing there stands out - does the NTFS partition mount o.k. in Suse, and can you navigate the files ???. Also let's see the grub conf
Code:
cat /boot/grub/menu.lst

There is a file called "/etc/fstab". You can look in that file to find the "mount point" of the NTFS partition. It is "/windows/C", or something like that. Suse should be mounting it. Open Konquerer, or file manager, and type "file:/" "Enter", and look for a directory that says windows and click on it. If there is anything inside, like a directory called "C", the volume is mounted. Otherwise, try "mount /mount_point. Mount point is the mount point from "etc/fstab", which is just a plain old directory. In Linux drives are mounted to directories, and drives also contain directories. The other thing is, SuSE adopted the insidious policy of installing the grub boot loader in the first partition instead of the MBR. So, you can put the SuSE CD in the drive, boot, act like you are going to install, but when it gets to the screen that says "new installation", click "other" and choose "repair installed system". When you get the repair screen, click on manual repair. Uncheck everything besides reinstall boot loader, and make sure it goes in the MBR. This is another terrible thing about SuSE, if you don't click "next" on the very same screen you check the MBR box, but instead go to another screen and then come back to the same screen you were on, your setting to install the boot loader to the MBR will be changed to "other". So, leave everything else the way it is, check the MBR box for where to install grub, and reinstall it. Then everything should work.

I suspect that the install to the MBR is o.k. - else highroller_100 wouldn't be able to boot Suse either.
No repair needed.

However if the boot sector of the XP partition did get trashed things are grim. highroller_100 enter the following from a terminal - it'll show us what that partition looks like
Code:
dd if=/dev/hda1 bs=512 count=1 | hexdump -C
There'll be a bit of output, just post it here - use sudo if needed.
